When the key is turned on I can hear the contactor close and then open. Dash display shows 39L, 39P, 74R. Scan tool says main contactor open for the 39 codes. Code 74R says fault with other controller. I have no troubleshooting info for these codes. My guess is that there a sensor or switch telling the contactor to open, or a problem with the left drive motor. Battery volts are 50. The contactor coil ohms 148. With a volt meter on the wires to the contactor coil I show 46 volts. I think a trouble chart would be necessary.
Thank you for any direction
