I bought an 86 IROC Z28 that had the orginal motor removed and a carburated 350 in it's place. Engine management removed as well. Problems started in the radio with it losing power then 10 seconds later the power returns. Also if the radio is playing and the headlights are turned on the radio loses power for a short while then it comes back on. I swapped out radios but it has the same problem. At times neither the headlights or radio have power to them but left alone for awhile will repair themselves. I played with cars for over 40 years but can't figure this out. Start replaceing circuit breakers is all I have. Anybody care to take a crack at this? Your help will be greatly appreciated.:icon_do h:
