I have a Club Car DS 48 volt 96 yr. model. cart just died while going down road. My batterys check good. battery pack reads 54.9 volts. Individual batts. read from 9.10 to 9.23 volts. I have tried to check voltage to solenoid and came up with 0 volts between small posts. Neg. side of solenoid to positive on #1 batt. reads 50.8. Pos. side of solenoid to neg. on #6 batt. reads -.758. I dont know what to do next and what would give me such weird readings?
