Hello all: I 'm sorry my posting was incomplete. I contacted HPEVS and they told that under NO circumstances should I use a contactor to interrupt the high voltage supply to the controller . My reason to install the contacter was to provide the Orion BMS2 a means of activating a battery discharge control because I already run some cells too low while trying to discharge for balancing the batteries and I don't want to have the car towed home again. After I installed the contactor and the problems occurred, I removed it and the Curtis controller continues to flash codes 66, 65,56,55, and code 46, which indicates an EEPROM failure . HPEVS told me the Curtis . 1239e will have to come back to them for diagnosis The odd thing is that the car can actually be driven . Is it fixable?
