Can you identify the location of the reverse relay, I am not aware of any external relay coils. Is it not built into the motor control box?

Hi Rob

The fault code states that current to reverse relay is too high during operation.

It advises to check that the reverse relay coil is not short circuit or the wiring to it has no shorts. Disconnect the coil and check coil resistance which should be around 160 ohms.

It also states if the code displays with the coil disconnected then you probably have a fault in the master controller.
