As regards you "miss", Definately make shure you have a good ground on not only the chrome box, but ANYTHING that grounds to the engine bay after paint. My car did fine after assembly, at first. Then, miles from home, it refused to start. After chasing my tail for several weeks, I put a jumper wire from neg batt to solenoid and WALA! Lesson learned, ALWAYS use star washers beween freshly painted surfaces and ANYTHING that requires a ground.
