Good evening all, we bought a 1955 A1 in fairly good condition, still 24 Volt, and has run great until just recently. It was parked and then somehow the key was left in the on position for probably at least 12 hours. Obviously the batteries were both dead when I found it. I pulled the batteries, charged them and hooked them back up and no power. I thought perhaps the coil or points had scorched, but they look fine. Any assistance would be greatly appreciated - the manual online TM 9 manual was no help.
