48 volt three wire charger/2 wire syustem
 

91 club car resistor 36 volt running 48 volts up graded cabling to 2 and 4 gage . a buddy gave me a 48 volt charger but it has the 3 wire set up for a OBC which this cart does not have. I understand that you can jump this sensing circuit out can anyone tell me how

open the charger and remove the 120V wires from the relay and jump these together. This totally bypasses the relay and the OBC wire.

(If charger comes on but the charger ammeter shows 0 amps, check the fuse at the charging receptacle under the clear plastic cover.)

this method should both be temporary measures for troubleshooting, or as an emergency method of charging the batteries when they have been discharged so far that the OBC will not charge them.
if you use your buddys charger you need to ether monitor charge or use a timer to shut off power ... if left unattended it will over charge your batteries
