Amp gauge reading 25 amps charging

[Kurt S]

Ignore the gauge. Get the voltage from the alternator right first.
The system is pretty simple - we're missing something.

I went back to the voltage regulator, and replaced the old style Delco Remy points style with the newer style from the parts store. With the car cold and with the battery charging I have 14.6 volts coming from the alternator. I drove the car approximately 7 miles and checked the voltage at the alternator. I had 13.5 volts coming from the alternator. Seems ok now. Of course the gauge is still off.

My temp gauge is still reading slightly higher than it should...like I have an over charge issue. I confirmed the temp is ok with a heat gun. I have 170* at the thermostat neck. When I run the car at a higher rpm but still in the City the gauge will go up. At idle the temp gauge comes back down. My lower radiator hose is new with a spring inside it. My water pump is new, the anti-freeze is new, the radiator looks ok. I have cleaned both ground wires on the radiator support. I have not gotten the car in the air to double confirm the starter wire hook ups. But I can see from under the hood that the purple wire is connected to the inboard connector.

Maybe the sending unit is wrong? It is new but who knows the calibration?

Thanks

One more note that I did not mention. Not sure it is relevant, but I always seem to get a light electrical shock when I tough the door handle. I am guessing this is due to a bad ground?

The static shock you are getting is due to the compounds used to make tires today and the static charges don't leak off to the road like they did with the older tire compounds. Has nothing to do with the car electrical system. It gets worse in the winter when the humidity gets lower too.....

Could be, but the tires on the car are 1972 Good Year Polyglas and my other cars don't do this?

Thanks

Different clothes and seat cover fabric contribute significantly to static electric shocks. When I wear my Flowmaster fleece jacket on dry winter days, I get a big snap when I touch any metal surface, also when putting my hand near the cruise control button on my DD's steering wheel. If I'm wearing my normal heavy winter jacket, I get nothing. Lots of possibilities on your static problem, but none of then are the fault of grounds in the electrical circuits of the car. As to different static problems, we first noticed them around 1969 or 1970 when I was working as a mechanic. Had quite a few complaints after selling customers new tires. The tire company we used had a rep that said the problem was caused by companies using less carbon in the construction of their tires. Much of the carbon was replaced with silicone products to give tires less rolling resistance. Can't comment on your exact tires, but that possibility also exists.

Thanks John.
