I was out breaking in my new 5.0 motor when all the gauges in my dash go out. The car still ran OK and I made it back home with no problems.

My 1st thought was it must be the constant voltage unit. I put in a new one then started the motor. Started right up, but the new unit went up in a puff of smoke. The gagues never moved.

I'm now sure I have a short somewhere, but I have no idea on how to find it. Everything is the engine compartment looks right and the ground to the engine is good. I remember hearing that you can trace back a short with a test light and disconnecting the positive cable, but I'm not sure how that works

Any helpful hints would be great. I spent about 10 hours today on this and got nowhere.
