I have a 2020 JGC with a 320 alternator for my system… during the summer it will dip down like 12.8 unless I give it some gas and it will rise to like 14… will this help keep the voltage stable?

@ianmurphy989 Жыл бұрын

Possibly if not upgrade alternator wire which sounds like may have been done. Will help with power drop in the heat. Also with that alternator I'm sure your system is rather large, run a capacitor. It will help stabilize your voltage womt increase just help keep It the same and healthy.

Hi, can the opposite happen. That is the amps are lower voltage is around 13.6 v. I have a Merc W204. Red battery light comes on. When I check on the cluster, I have voltage at around 13.6 v and the IB moves between -50 to about 30.

I replaced my battery, replaced my alternator, and thereafter my headlights (low beams) got fried because of the PCM/EXU on my '02 Mazda Protegé5 is faulty. The voltage regulator is inside of the brains. So I gotta replace and check to see if that fixes my high rpm sending an overcharge throughout the car.

I have a 2013 Cadillac CTS Performance. On mine sometimes when I start the car the voltage will read 14.9 or 14.8 never higher than that, when I drive it goes down to 14.4 then 14.5 and may stay constant at 14.4 again. Im not sure if this is normal. It is a new alternator and battery is fine. Is this normal?

If voltage increase amperage decrease

@zmillm9916 Ай бұрын

No it doesn’t… V=IR where V is Potential difference (measured in voltage) I is current (measured in amps) and R is resistance (measured in ohms) therefore V is directly proportional to I, meaning that as voltage increases so does current.

@RJLenny00 8 күн бұрын

For the power to stay the same, if voltage increases amperage decreases. P = V x I If they both increase, wattage goes up as well Pretty sure that’s what the comment was referring to

hey brother plz reply back , i am having ford fiesta diesel , whenever i start the car battery warning light comes on the dash but if i revv the car till 4k rpm it disappears , and wont come back till i turn off the car , what is the issue

@easyautofix 3 ай бұрын

It sounds like the alternator isn't putting out the correct voltage at idle. Revving the engine increases the alternator's output, which can temporarily raise the voltage and turn off the warning light. Using a multimeter what is the voltage of the battery when the car is idling? Also, what is the voltage of the battery with the vehicle off?

@motologist1917 3 ай бұрын

@@easyautofix when the car is on ignition it is 11.6 but when i start it is still 11.6 to 11.4 , but if i rev it will be 14.2

@easyautofix 3 ай бұрын

@@motologist1917 Thank you for providing the voltage readings. Based on the information provided, it appears that the alternator is not adequately charging the battery when the engine is idling. A healthy charging system should typically produce a voltage of around 13.5 to 15 volts when the engine is running. The fact that the voltage remains low (11.4 to 11.6 volts) even when the engine is running indicates a problem with the alternator's output at idle. The increase in voltage to 14.2 volts when you rev the engine suggests that the alternator is capable of producing the correct voltage under higher RPM conditions. Given these findings, it's likely that there is an issue with the alternator itself or its associated components such as the voltage regulator.

Funny, I found out newer vehicles, a failure of this regulator is bad, though older ones it is not as serious depending on your customization. I thought I could let this go, but since this is newer it is even worse. Correct me if I am wrong, but it seems things changes in recent times. I am no mechanic, just doing research. Though as we know, Google is not a 100% accurate source of information. The battery cell went bad so we replaced the battery, we do not use amps or speakers ect, but it seems this does not matter on the newer vehicles. So I guess I was wrong, possibly could be wrong about this as well.

I have an external voltage regulator and I can get power from fuse box that turns on when the key is on. It should work but it's not Alternator is new and checked and voltage regulator is new too.

@@LubaLuba1 Have you checked the decoupler pulley? Think of it like a clutch for the alternator - it lets it spin freely in certain situations. If this pulley isn't working right, it could mess up how the alternator charges the battery. kzfaq.info/get/bejne/m52JZpOLs7Ldn6M.html&ab_channel=Anttiajt Additionally, have you checked the alternator fuse? A blown fuse can disrupt the flow of electricity to the alternator, preventing it from charging the battery effectively. Lastly, ensure all wiring and connectors are tight, especially those connecting the battery and alternator. Loose or corroded connections can impede the flow of electricity and cause charging problems.
