We recently ran into an electrical issue with our Lingenfelter preped LS-1 engine, that would come and go at random. The engine would start to miss, then quit completely at the track. On another occasion at the races, the engine ran, then died when we pulled into the pits for a flat tire, and would not refire. Later back at the shop, it started with no problem. We ended up tracing and checking all the grounds, and found a loose connection, at the positive side of the battery terminal. The lock nut holding the cable had vibrated loose. It was covered with a plastic terminal cover, and could not be seen until we removed the Optima AGM design battery to check it's status. The cable was still connected, but with no positive force. Always check the basic battery and ground connections with these cars. There is a ground on the back of the right side cylinder head. There are also a series of fuses in the electrical system. Our car has an eight fuse box, located by the driver. Very close to the OBD 2 port. Make sure the battery is on a trickle charger all the time, and stays fully charged, when the car is not in use. For a battery charger, we prefer the C TEK micro processor controled unit, shown below. It is compact, and simple to use, with a easy to read level of charge indicator.
