Yesterday I installed my freshly rebuilt 440 in my old charger. As we were trying to get it started, after I cranked on the engine a few times I lost power to pretty much everything. There is power to the starter relay and when the ingition switch is turned on there is power on the out side of the starter relay. However, the engine does not turn over. Also, there is no longer power to the aux circuits like lights and horns and there appears to be no power to the fuse panel under the dash. Any idea what may have happened. Note, I had one of those trigger switches hooked between the battery and starter relay so I could find top dead center but don't see how that could have been the cause of the problem since the switch was not being pressed at the time we were actually trying to start the engine.
Thanks,
