Hi All,

We have an older hyster stock picker that is having a few issues. Basically we cant move it! It will go up, down, etc, but wont engage the traction wheel to move forward or backward.

This is not an issue with the relays - they were recently replaced and are brand new. We have found when the issue occurs the steer by wire module doesnt power up and then the traction motor wont engage.

We are thinking its a card problem - any ideas?
