@jptrucker29 Yes, you can do it checking amps directly. This method does it indirectly by measuring voltage with that resistor in place. I use this because direct amp measuring can easily burn out your meter since all the current has to run through it. That resistor I used got so hot during filming I burned my finger. I'd rather mess with a two dollar resistor than a five hundred dollar meter system that I use. Scotty Kilmer

I can see where a current measurement and/or voltage drop would be very accurate but I find that a test light shows enough even on newer vehicles since a test light bulb will only glow a little from minimal current flow. (Clock light, computer, etc.) A glove box light or any similar draw that is enough to kill a battery overnight (or sometimes two nights) will cause a test light bulb to glow brightly. I can see though that on occasion there is cause to need numbers, but I have not seen that yet. Keep up the good work Scotty, your advice is good.

I like the resistor test lead idea with the parallel volt meter. I used the Amperage function of my multimeter hooked in series with the negative terminal. You have to make sure all high amperage accessories are off or your draw may cook the meter (heated seats, fan, radio, dome light door override, etc..). My parasitic drain came from a faulty overhead DVD player wired to an always-on 12v outlet circuit.

Depending on your multi-meter You could actually just place your multimeter in sequence with your negative battery terminal and negative batt cable. Then just wait 30 mins and check to see what your drain is. After 30 min of waiting for the cars computers to turn off, an acceptable drain would be .003 mv, anything more, you should test your fuses with your multi meter. That way you dont have to unplug all your fuses.

Hey scotty, heres an easier method to test: disconnect the negative battery terminal, hook a multimeter positive on the negative battery terminal and negative to the negative battery cable, set the multimeter to read amps, take note of the number. Then pull out each fuse one at a time. I would start with the fuses in the cab of the car. Once the amperage drops, thats the component thats causing battery drain.

A cheap meter will not read current (amps) at all, or will burn out immediately if the current jumps too high even for a millisecond. Reading the voltage across a one ohm resistor is an excellent idea.

That's a whole lot for this video! One of our work vehicles has had a drain for more than a year. We have to start it up and take if for a drive every three to four days or it won't start. It has a new battery, that I recently had tested along with the alternator. There must be something draining. Now I'll be able to check for the drain, while avoiding an expensive auto electrician.

Nice guide as always. It's a good idea to lock the car, including the hood lock and let it rest for 10-20 minutes for all of the computers to shut down. There are always some computers that stay on for a while after the vehicle has been locked. These will give faulty readings. I usually let the cars I work on 30-40 minutes just to be sure.

Scotty, I've always enjoyed your vids and you totally threw me through a loop on this one. I've always checked for parasitic draw by connecting an ammeter in series, and I am also familiar with checking for draw through fuses. I put my meter on the test ports of each individual fuse and look for a voltage drop, which would indicate that "juice" is flowing through it, since all fuses inherently have a resistance value. Are you doing the same thing here, just at the battery? also, your meter is impressive but a bit intimidating, I understood the Mv readings but maybe scale it down to a laymans meter so other guys can get in on the action too.
@mmpiforall5913
@mmpiforall5913 8 жыл бұрын
+jheetman Actually Scotty should have mentioned the "35 millivolts" is equal to 35 milli-amps ( mA) when a 1 ohm resistor is used. However if you have meter like the one he used, they have a Amps function and you can set the range to measure the current directly - no need for a resistor - so I'm surprised he made the Vid he did.
@excavatoree
@excavatoree 8 жыл бұрын
+jheetman Yes, he's measuring the voltage drip across the resistor like you measure it across the fuses. The voltage drop is directly proportional to the current draw, so it's just as good as measuring current with an ammeter. Because it's a 1 ohm resistor, 1 millivolt across it means 1 milliamp, one volt across it means one amp, etc. I=E/R, and R=1.

The idea is to measure the current draining. In this case since Scotty has voltmeter, he can only measure the voltage across the resistor. He used 1 ohm resistor, so basically the amount of voltage he measured is the same amount of current draining. (V = I R) But if you have multimeter, meaning you can measure both current and voltage, you don't need the resistor, just put the multimeter in current setting and connect it in series.
@excavatoree
@excavatoree 8 жыл бұрын
you might want to mention that the current draw is really in amperes or milliampers, but you are measuring it indirectly by measuring the voltage across the 1 ohm resistor, which conveniently gives you a 1:1 correspondence. (1v = 1 A, 1 millivolt = 1 milliamp, etc.)

@ Tim McQuate - When you find the drain, why not make a video and help people who didn't get helped from Scotty's videos. I am not holding my breath over your video coming up anytime soon.

Hey Tim - Here's the technique to answer your question. First test using the 1ohm, 1000W resistor like Scott said in the video. He said up to about 35mV across the resistor is acceptable. So if you read 35mV, you know you have 35mA of drain current by ohms law. See my previous comment if you need that explained. At this point you know you have a leak, you just don't know where. So start pulling fuses to try and make the current flow stop like in the video. If that does not stop the current, then it should be leaking back through the diodes in the alternator or the problem is between the battery and the fuses that you were pulling. So, disconnect the alternator wires going to the battery to test the diodes. Otherwise, you have a skinned wire shorting to the chassis between the battery and the fuses. You called it a bad ground. The easies way I know from here is to get a DC current clamp and start testing each wire as is splits off from the battery on the way to the fuse boxes. Hope that helps.

newer models have extra drain, find out what it is for your particular car if it shows larger drains.

@MAIMPORT all batteries come with dates stamped on them. If you suspect one, check the date. Or have it checked with a battery checker, I use a midtronics MD 500 tester. Scotty

@paulhunter123 it doesn't override anything, it just takes the load of any power drain so nothing melts when testing.

that means a relay is turning on and off, so check that first, though some cars will blink for a few minutes then stop, and that's normal for them

@rosmob719 you have a massive short, first unplug every wire from the battery and fuse box. When it has no drain, slowly put em back one at a time until it gets hot again.

@winglajones the resistor cost 2 bucks at radio shack, use one for testing. Now if you remove a fuse and the drain goes away, that stops the drain. IF it runs a device that you don't need, like overhead lights, you can drive it that way and it would be fixed. BUT, if it runs something like the ignition system, then removing it will not let the car run at all, so it wouldn't be very useful to do that. Scotty
