voltage

Postby burntice51 » Tue Aug 10, 2010 9:07 am



I have an 83 Aspencade that is charging but is only running at freeway speed between 12.2 and 13.0 volts. Can anyone give me any ideas ? The stator is working because the volts are changing while driving but they are not as high as they should be.

Are you running any extra lights or electronics? The stator is sized to provide just enough power. If you want to run extra lights etc switching to LEDs helps.

Next you should check the condition of your battery. A battery that is dieing sometimes won't take a charge as well. I noticed with my new battery the voltage would quickly go up to 14.5 and stay up there. Now that it has about a year on it it doesn't charge up so easily. It was a cheap battery and I knew it at the time. I am thinking of getting one of those maintenance free / sealed batterie next time.

Yes it does have extra lighting but set on a toggle swith and I don't run them all the time. When I do put them on the voltage does drop even further. The battery is brand new and is filled with fluid and was trickle charged to full capacity. I am stummped here !!!!

Charging between 12.2 and 13 ... with varying rpm? What about your meter is it accurate? If your battery is new and it doesn't show 12.4 or more at rest with engine off then it would seem that your stator is shot imo. Even if you are getting a reading if it's not enough to keep your battery charged it is worthless, assuming you have not overlooked some other electrical load.

If there is a connector along the 3 wires from the alternator (normally yellow I believe) then you can disconnect and check for continuity on each wire to ground. If there is any non zero reading your stator is bad. If the connector has been removed and wires hardwired together you will have to cut the wires to check continuity.
