Overcharging problem help!
The car is so close to being done! But now, I get to work the bugs out of it, the kind that only show up when you start driving the car. I've been cruising up and down my road with it to see what works/ doesn't work. So far, I've found the tailpipes are hitting the rear diff, the brake light on the dash comes on periodically.
But, my question. With the car idling, the amp gauge hovers just on the charging side, like it should. As soon as you rev the car up, the gauge basically spikes over to 40A and stays there till the revs come down. I put a volt meter on the battery, and at idle, it's around 13volts (perfect!) but when you rev it up, it goes up as high as 17volts. That's way to high for my liking. Almost everything on this car is new (doesn't mean it's good though!). It does have the original voltage regulator. I've read several posts on here about this problem, and I still believe the voltage regulator is the problem. I've read that it was a common practice way back when, to adjust them to produce more voltage, for brighter lights, etc? If so, perhaps I can simply re-adjust to a lower voltage? I just wanted to run this problem past you folks, before I tackle it.
