I have a 79 SA that i just purchased, I got itrunning but it doesnt seem to charge the battery, and the GEN light and Oil, lights are on.. i tried a new voltage regulator but that didnt do anything, but now when I unplugg the voltage regulator the lights seem to go off, can I get some help?

 

I had that problem last year and i goggled "checking the alternator"
and found some interesting info

 

Check the ground wire
