In this video we go over Regulated Voltage Control/ ECM Controlled/ PCM Controlled charging systems, typically found in many post 2000 GM vehicles. There are other manufacturers that use a logic system to change voltage output of the alternator depending on conditions but we are focusing on General Motors.
We discuss you components to the system and different charging modes you may encounter on your daily commute.

AnthonyJ350 hey again! Sorry for the off topic, Hey again! I’m trying to reach out to you on your latest KZfaq video and here hoping you could save me once again My 350z 2004’s stayed unused around 20 days under temperature ranging from 10 to -2*C since the last ignition I tried to start it yesterday and today, but the battery seems to have died even though it’s 6 months old A shop nearby used an amplifier to keep the battery running, but we couldn’t start the car, though fuel pump seems to work properly, as everything else I’m thinking it’s Alarm/NATS because the red light above the wheel is constant when the key is in ON mode, when it’s in ACC, the light is flashing Could you confirm that when the red light is constant in ON mode, the car will never start. Or would it stay constantly red in ON mode because it’s usually so? Thank you greatly for any reply, I’m quite desperate right now

I just bought a 2013 chevy Tahoe LTZ. I ran a 0 gauge ground from battery to fender and another 0 gauge to the alternator bracket. I also ran two 0 gauge positive to the rear for a 2nd battery. I was looking at the factory ground to the engine block that had that sensor. That ground engine block wire look big enough look like almost 0 gauge but I think it's 2 gauge. Will it's be ok to run it like that, I have factory alternator. Will upgrade to mechman later.

Although this was posted 5 years ago, a BIG thanks for it. I was scratching my hair out, wondering why my voltage gauge in my 2008 Chevy Avalanche is dropping down to about 13V and, at random times, going up to about 14.6V. I decided to check on this when I noticed the Current Loop sensor on my ground wire from the battery while cleaning up and replacing rotten wire covers. Thanks for the information as I am from the old school that thinks that alternators put out a constant 14.x volts. Here is how I now think I got to this point and maybe others can relate to this - My voltage gauge was always showing over 14V because my previous battery was getting bad and was not reaching a proper SOC. It was when it got noticeably bad where my truck started to struggle to crank that I decided it is time to change the battery. I replaced it with an Optima Yellow top and that is when the voltage gauge started to read below 14V at random times. What made it complicated was that I was also tracing down a misfire issue (#6 Cyl) and started to think that the misfire issue was related to the battery voltage, not knowing what I know now. Thank you for this video.

That's the problem I've been having with my 2011 CTS with a Mechman 240 amp alt. I have a 4000 RMS amp on 2 -12'" and 1200 RMS 4 ch amp when I start jamming certain songs like the song named Previously by PAYROLL GIOVANNI&CARDO the alt starts to ramp up to 15.7+ the service power steering and traction control message pop up but it's fine after it goes back below 15.7 volts. I bought an SMD VM-1 and connected the ground and constant directly to the sub amp to get a more accurate reading. All this time I thought something was wrong with the alternator so I need an external RVC. Thanks for making this video.

Finaly... the information i've been lQQking for, i just picked up a used 2005 GMC Sierra 1500(single cab/shortbed/4.3L v6/automatic/181k original miles), my first truck ever, it has the same guage cluster shown in this video, and im from the USA btw. Just after starting the truck, the factory voltmeter guage would be at 14v, then after driving around for around for a few minutes, the voltmeter would start to go downwards, showing less voltage, and this is during daylight hours, but when its dark out, like heading off to work in the early morning, the voltmeter guage stays at a constant 14v like normal. Now knowing what GM has installed on most of its newer vehicles, the clamp meter on the negative cable side of the battery, this all makes sense to me because of its design, i have a brand new battery thats within 2weeks old, it starts up fine, and honestly, i was ready to pull the alternator out to have it checked, now i see i dont have too, everything appears a-ok. FYI, i happen to have a "ScanGuage" device that you can mount on the dash, by velcro, in front of the factory guage cluster, or elsewhere if you prefer, and it connects directly to the OBDII port, you can check all sorts of vital information with it that the PCM sees. I set the scanguage device to the voltmeter function and watch it as im driving, after starting the vehicle, the display shows 14.4v, and dips down as low as 12.6v after driving around for a few minutes, and that is during daylight hours, again, when running in the early morning hours when its still dark out, the display shows a constant 14.4v for miles on end, no doubt because of the electrical load from the headlights, driving lights and tail lights that automaticall come on with no other accessories in use, other than listening to radio/cd player at low volume, other than that, the truck is factory stock.

@@williamgonzalez7167 Theres no problem, its completely normal.... look for a device thats attached to the negative battery cable near the negative side of the battery, it senses the battery voltage. As the alternator charges up the battery after starting the vehicle, the instrument cluster guage will typically read +14.4v at first, then slowly drops down as the battery is being charged back up to its nominal voltage of +12.6, its GMs way of not overcharging the battery and shortening its life and/or cause it to swell up prematurely, smart charging basically.

Started driving again and about 75 miles into my trip the voltage drops again. I am Like WTF! so at this point I decided to just keep going and get home. But then from time to time the voltage would come back up and then drop again. I asked the service dept at Chevy what the deal is and they said that this was the way the new ones are designed! WTF! Wish I knew that! Would have saved me $175 on a alternator! Wish they would inform people of this when they buy these vehicles! Not to mention this just does not seem normal to me. Voltage drops I automatically assume charging system is not working.

Great video. Very informative. I have a 08 suburban LT. Been having some weird electrical issues. Started with locks clicking up and down and speedo and tach going crazy. Other messages on DIC like stabilitrack. Replaced alternator and everything seemed fine. Then started having an issue where I'd park the truck and turn off. Come back out to start up and nothing happens. No key fab unlock, no lights on dash when I put key into ignition. Truck wouldn't turn over or anything. I'd jump it and it would turn on. So after all this I replaced the alternator and battery. Not the top of the line battery and 160 amp new alternator. Had the same thing happen, voltage dropped real low, parked it and turned it off and had nothing when I tried to start it. Called AAA and by the time the tow truck got there, about an hour, I tried starting it and it started up. I exchanged the alternator again and so far it's been ok. I do watch the dash more carefully. It does fluctuate but seems to run real similar to your video. The lowest voltage I'd see was around 13.2 volts. I left a multimeter hooked up and turned the truck off and saw voltage go down to about 12.79 volts and stayed there. Started the truck and it went to about 14.78. Crossing my fingers! I love my grocery getter.

Thanks for this video. I have a 2000 Silverado 1500 LT loaded except no OnStar. I also have a 600 watt amp. I don’t see the clamp for PCM controlled voltage. My battery at rest today was 11.8V. After running it shows 12.6V. My issue is my volt meter (dash) at start has a rapid bounce between 14-17V. As soon as the idle lowers below 1000rpm it sit at 14+. When I drive, the same thing happens above 1000rpm, then come to a stop and it’s steady 14+. I noticed you changed the normal small alt to junction block wire to a large gauge wire. Could it be that small wire (fusible link) causing this? I’ve been chasing bad grounds but I’m stumped to the cause. Please help if you can.

The problem was running thicker gauge wire from my stock alternator straight to the battery. This was keeping my battery charged 15+ volts for longer periods of time and with playing my sound system loud it would cause my abs light to come on. I got better voltage regulation with running the 0 gauge wire from the alternator to the red box. I figured that if I run a thicker wire from the alternator to the red box the regulated voltage control would work properly. Now my alternator doesn’t charge the battery past 14.8 volts and after my truck runs for awhile it will drop down and hold at about 14.1 volts

@robbob1693 5 жыл бұрын

In actual fact the ceiling of 75-80% SOC is not to prolong the life of the battery because it wont, it is limited to that soc by the engine management unit from engine driven charging only, the other 25% space in the battery is left for high voltage intermittent charging from regeneration which if that occurs takes the battery SOC to around 100%. A lead acid battery whether flooded or glass mat needs to be fully charged on a regular basis for longevity. The main reason for the high percentage of failing batteries in modern vehicles is stop/start and smart charging. The fuel gain from these two systems is marginal and the AGM batteries needed for this system cost at least twice the price of flooded and have a considerably shorter life. Anyone that hates the stop/start system can deactivat it simply be disconnecting the sensor attached to the negative lead of the starter batter, see video. I have done this on two late model Merc`s, there are NO issues, NO CEL on dash and both passed the UK MOT with sensor disconnected, Google ( AGM AFTERMARKET FALTERS AS DRIVERS DISABLE START-STOP FUNCTION ).

My Ford does the same thing, if I want to really bump I turn up the fan lol. An Adjustable Us Alternators pcm is on it’s way to me as we speak. My 2014 edge can handle up to 16v, but my 4K rms sundown amp can only handle up to 15.5. the main thing I want to stop is when it drops to 12.9v without having to increase fan speed. That’s a big difference in sound output from 14.4. I figure I’ll set it around 14.8-15v. Singer 270a alt, Xs power d6500 under hood, sky high 1/0 throughout. I do however still need to upgrade the two smaller wires going through the ring sensor thing just before the negative terminal plate on the battery.

When I turn the truck off with the headlights still on the pulsating stops and the lights are steady. The battery is about a year old and good quality and the cable connections clean. The alternator was replaced 7 months ago with a remanufactured alternator.

Great video, I did not know about the Battery Current Sensor or the RVC system. I'm currently running a AGM 12V 1000 watt 18 ah Power Cell as a secondary for my Class D amp in my 2010 awd Escalade Luxury. I have my main 0 aught wire connected to the main battery under my hood in the engine compartment. I'm running that 0aught wire back to my power cell in the back and then I grounded to the back floor panel (grinded the area down to bare metal first). Would I need to somehow run a ground through the BCS for my amp? I got my new Sensor a few days ago, so I'm looking for your opinion on how to disconnect and reconnect the BCS Sensor.

Problem is my current sensor floats between 12.5-13 so my smart isolator doesn’t kick in and charge my 2nd battery. The current sensor just bounces between 12.5-13, and when my regulator does bump up voltage past 13.2, my second battery kicks in and causes the sensor to bump the voltage back down under 13.2. And just cycles that over and over. Any suggestions? The one thing I’ve done that makes the dual battery set up work perfectly is unplugging the sensor. When I do that my system stays at a steady 14.3 while engine is running

I got a 400amp alternator for my 08 trailblazer has 3 batteries and a 8000 watt rms amp……I just got a voltage regulator that’s higher 15v it should still sit around the normal 14.7-8 I’d say…….doc you think this is a good move ?

I would want the voltage to be at 14.5V - 14.8V

Possibly, your car is under warranty still. Did you try bringing it to the dealership?

I have a 2500 same gen as you and the volt gage on the cluster fluctuates back and forth every second, but the voltmeter says its far more steady. Any ideas?

At 14v

It's possible the stepper motor in the gauge cluster is faulty, it's a common thing to happen on these trucks.

My 2018 Chevy Malibu has the Regulated Voltage Control System and I have an amp and sub. 600 watt RMS at 1 ohm single 12" subwoofer with a 800 watt RMS at 1 ohm mono amp. And in the first time I start the car and go to work at 12 pm my voltmeter goes to 15 volts for a while even with the radio. Do I need a battery upgrade to keep up with my power hungry equipment.

I would upgrade the grounds and it doesn't hurt to put a Northstar Battery in.

i would like to know how to bypass the pcm so i can do the big 3, i have a 2011 impala with the sensor on top but its just too small to run 0 gauge through it

You can get an external voltage regulator to work with your aftermarket alternator.

So a big 3 upgrade wont work on a car that has a regulator ???
