what voltage should i be running at idle?
i havfe an autometer voltmeter, and it says that i have aroun 10 or 1q1q volts when the lkey is in the on posi tion, but then when i get i;t stzarted and the motor idles, it goes to about 13 or 142. is this acceptable?

yeah, 142 would a lil much i guess. lol what do you get when you put the key in the ignition and turn to the on position?
|
Ok I went and checked for you(aren't I nice lol) and I get 12.4 with the key to the on position. Turned the headlights on with the car off and it dropped to 12.1. I do have a brand new battery though. All that shows you is that my battery is stronger than yours. How old is yours anyways?
|
A brand new battery with no draw should be resting at 12.6 volts.
The car running to charge that battery you would need 13.2 volts minumum, preferably 13.6 volts +. A new or rebuilt alt should have the voltage at 14.4 to 14.6 volts. Anything under 12.6 volts while running and you're draining the battery. above 15 volts is bad! |
You should have at least 12V with the ignition on, and then ~14V with the engine running. Much less and I'd get your alternator check out.

well, i just got a new battery, it is one of the optime gel packs. it was donated to me. so you are saying that i may have a ground problem or an alternator problem? easiest way to test alternator? any usual ground problem culprits?
|
I always get 13-14 when idle, 12 when startup. But that is reading w/ a stock gauge....
|
i am not reading with a stock gauge. and also, i have 3 autometer gauges and the electric fan pulling power as soon as i turn the ley to the on position. coild that be part of the problem?

I would be checking the alt before anything else. |
Optimally, it should be around 13.9-14.2 with the car running and no load on the electrical system. Anything under 13 and you need to look at the alternator circuit. The ECU is designed to run within a certain voltage, not enough and shes not happy.

the gauges have lights and they are electricla gauges, so are they not pulling power? and as for the fan, i am going to rememdy that problem as soon as possible
