AL01, 1 flash.

Condition- Connection/communication error between control card and traction motor.

Truck response- traction and hoist functions diabled.

Possible cause and test proceedures

1) Loose or damaged elec. connection between control card and controller. Verify connection at controller, verify wire harness connection at base of steer handle, verify connection at control card.

2) Damaged or defective control card.
Measure voltage at pin 5, connector C on the controller. W/ control card disconnected, this should be about 12V; w/ the card connected, it should be about 3 - 9V. A reading of 0V or 12V w/ the card connected means that the card or connector pins are damaged.

I would double check where you connected the handle.
