i went to the customers location this morning the batteries had grease on the terminals ,lots of grease and there was 22 volts measured across the top of the batteries. after cleaning and flushing the battery compartment the case voltage dropped to.224 volts.the pallet jack seems to run normal at this point.i sincerely appreciate the help. it always pays to use the kiss system first.
