Hey guys. Got a problem here and hoping you can help. I have a '69 Camaro with factory dash harness and M & M engine and front harness. Factory tail light harness. Has an HEI distributor and an electric choke. Harness was designed to take the external voltage regulator out of play and provide proper voltage to HEI. This thing is eating thru batteries! Lights switch not on, no bulb in dome light, etc. I had my Centek charger on it all winter and it stayed charged nicely. I started the car up two weeks ago and took charger off and left it off. Today, dead battery! I have gone thru two optimas and the one in it now is an EXIDE Orbital. What are the steps I need to go thru to figure out where this drain is?
