Just purchased a cart. 98 EZGO...has HD solinoid, "Beast Motor", Big controller (not sure what size got to remove it and see its not alltrax its a stock big body curtis) lift and a few other accessories on it. Got to replace battery trays, some bushings...but here is my question. Cart was a 48volt. the second owner converted it back to 36volt but he did nothing w/ the charger. The charger is a Powerwise. Outside says its 36volt, but the TXT plug in is painted yellow and has "48 volt" wrote on it w/ a marker. is there a way to tell if it is a 48 or a 36 w/out plugging it up to a cart? o and ive got to replace batteries all are bad and i need to know if i should get 6volt or 8volt
