The car is a 1972 Challenger with the original low compression 340. When I put it into storage last November, the car ran perfect. Over the winter, I pulled the battery (which was nearly new), and kept it indoors. Voltage remained at 12.7 V without the use of a tender.
Earlier today, I put the battery back in the car, and attempted to start it. The clock, headlights, and accessories all work fine until I attempt to actually crank. It sounds like the starter wants to to turn over, but before it can (less than a second after turning the ignition switch to start) all electric power is lost. Briefly disconnecting/reconnecting the negative battery lead resets everything, but the same problems persist.
Before I proceed down the path of diagnosis by repair (beginning with the starter solenoid?), I'd *really* appreciate any advice you all could offer.
Thanks!!!
