Ok so today I took the car out for a good 20 mile run to shake it down. I noticed when I started it the red light did not come on. When I got home the starter was dragging like the battery was dead. So I check voltage and I am at 10.4 volts with both a new starter and battery. I was not happy with the connections on the postive side of the battery so I reconnected them with a new clamp. Get in the car and turn the key and the red alternator light came on. I let it run and charge up and go in the house. I just went back out there and no red altenator light at start up. The bulb is good and I am getting a voltage drop with it running if I turn on the lights.
I pulled the motor a ocuple of months ago to fix some leaks and for a full paint job. I checked and I have a solid connection at the starter for the altenator. The 3 prong plug is solid on the fuse box. Any thoughts? The Altenator has never gave me any trouble while I have had the car.
Thanks

go and get a new regulator. There cheap. It may fix the problem. Also check your grounds. Might be a bad ground.

Ok I did some checks after searching on here. Most people have problems of the light never going out. When Mine lite up it was on to abotu 1500 and went out.
I did this as suggested on the board. "You can also do what is called a "full field" test. Jump the field wire to the battery positive. The voltmeter should show about 15v like this. If that is the case, then replace the voltage regulator. "
When I jumped the wire the engine bogged down a little and the voltage on my voltmeter climbed from 12.4 to 15.2 and I took it off. Did it again and same result. Sound like voltage regulator? I am going to grab one at lunch and hope that cures it.
Thanks for the help

I bought the replacement from AA that goes right on the panel. Clicked it on, held breathe, turned key and woot woot red light on dash. Car is charging at 13.5 at the batter on my meter so it appears that was the culprit. Fingers crossed.
Thanks

How long has it been since you replaced the ignition switch? I had this problem in my 75 1.8 and was solved by replacing the switch. Good luck.

Check the bulb, it will not charge if the bulb is burned out or if it is not the larger 2w bulb. Don't just throw parts at it.

Thanks for the added troubleshooting tips but it was the VR. I did test the bulb and did a test to see that the Alt was working before I got the VR.
