Ok but when battery fully charged and you turn key on it does nothing at all. No horn no nothing. only time can get to do something is when charger is put on it. even then the horn barely makes noise and tack stays up at 8000 does not come back to zero. if i unhook the wire from start switch to coil then the tach goes to zero. Have tried 2 different batteries all do the same. I would think that when a new full charge battery is in there and i turn key it should light something or toot horn or something but acts totally dead.
