Wrong voltage on one phase --> failure in power section (low leg), driver circuit, or motor in master controller.
The R indicates this problem on the right motor.
* Ensure power wires are connected to correct terminals.
See the section Diagrams 8000 YRM 1081.
* Check the resistance of each motor winding. Each
winding should measure approximately 10.00
±0.10 milliohms (48V) and 6.10 ±0.10 milliohms
(36V).
* Ensure each of the motor windings is not shorted
to the truck frame.
