I have a restored 1940 w/216 all parts are either used, n.o.s. or rebuilt with new 6v battery on truck. Anyway, I've always had a weak battery after running awhile and wouldn't have alotnof pwer to crank after a drive... It would static charge after a few hours or days and go back to normal but this wkend when I [censored] off the battery is completely dead dosent even click and has not static charged, I'll throw the batt charger onnit tonight but how can I correct this problem?
