Electrical Gremlins- 69 Camaro

[g356gear]

I have been working on a car that was restored in 89 and has been sitting since....only 250 miles in 20 years. I am having the following issues....

1. Amp gauge is fine when car is idling. Turn on running lights and the amperage is fine. Turn on headlights and amperage drops. Ideas why? Maybe regulator or faulty alternator?

2. Signals are not working. I am thinking a ground somewhere for this problem since the dash was out to replace the tach that was sticking.

My turnsignals stoped blinking in the dash, but still worked outside the car, after swapinmg hte curcit board on the back of the guage cluster. I took some emry cloth and scuffed the copper where the harness connects to the circut board and where the lights contacted the copper on the curcit board. That fixed my problem.

Make sure you have the ground hooked up to the back of the guage cluster as well. If you wanna make sure you are getting juice to the turn signal lamps in the guage cluster you can use a test light. Ground the light and touch each side of the copper where the light makes contact with the curcit board. One side or the other will make the test light blink. If the test light doesn't blink then test at the turn signal contact on the wiring harness connector.
