Recently had the dash out of my 69. Now after it's all back together the gen light is on. All other gauges and lights are working properly so I'm thinking ground is not the prob. The odd thing is when I turn the key to the on position it does not light up. Only after the car is started. I pulled the cable off the battery last night while it was running and it continued to run so I'm pretty sure the alt and reg are working. Any ideas?
