3.5 Five Bars - Right Motor Wiring Trip
The right hand motor has a short circuit to a battery connection.
Test Right Motor Short
Check that the batteries are fully charged and in good con- dition, and check all cables and connections. Check the connections to the right motor, look for a loose or damaged connector. Take a resistance reading from pin 2 to pin 9 see (figure A3.5.1). Take a resistance reading from pin 2 to pin 7 or pin 8 see (figure A3.5.2), if the all the circuits are open (resistance is greater than 10K ohms), then replace the controller.

A3.5.2
If the all the circuits are open (resistance is greater than 10K ohms), then replace the controller.
If the reading is short (resistance is less than 10 K ohms) on any of the readings, proceed to check the
