battery/alternator gauge...

[bolden3]

does any one know why under acceleration my gauge jitters between 14 and 15 volts?

as long as you are charging 14 volts and up dont worry abou it. alernating current is never a constant number

mine goes all the way into the yellow when i am heavy in the throttle and high in the rpm ranges why would it do that?

I notice mine hovers around 13 when i'm cruising with the a/c on. Sometimes at red lights it'll drop right to the edge of the yellow, but them move back up to 13 when i start moving. it's only at 14 for about 5 minutes when i first start it. Is this a sign it may be going out?

Alternating Current is pretty much everything in your house. Your Computer will change the alternating to direct current. Anything that runs on a battery is also direct current. Even cars that have alternators.

In short, All cars are direct current.

Ok? If you disconnect the battery on a car after it's been started, it will keep running off the alternator. I don't care if you want to call that power A/C or D/C, but it's usually around 14 volts and mine is typically at 13 and sometimes into the 12's under load from the air conditioner and fans. Is this a sign of the alternator starting to go out?

Exactly what mine does, dunno if it's normal or not though, I really only started paying much attention to it after I dropped in a new red top a few days ago.

My LT1 Camaro was always at 14, so that's why I was wondering if this is normal for LS1's or something?

I guess with A/C on (with fan on max), headlights, radio, and then you come to a stop (brake lights) and then if it's just above the yellow, it's probably all good.

The way I'll know for sure if the alternator is bad is if I go the start it and the battery is dead...so far so good, but I would feel a lot better if the gauge read higher under full load.

I guess we would need a higher output alternator for that.

[p_funk22]

Yeah. Every car I've owned has had the alternator go out. Luckily it's not too expensive and I can do it myself. If it does go out, I'll just get a heavy duty one.

There ya go, then you can get a more powerful stereo, and have it happen all over again.

your car doesnt run off your battery, you can disconnect your battery and itll run unless your alternator is kaput or you have put such a huge electrical drain

DUH.

I never said the car ran off the battery.
