I have troubleshot this problem with a multimeter and have narrowed down to the handle I believe. The battery pack checks good at every terminal. I am getting a fault 1-1. Which is a generic battery fault. the forklift operates fine, we have replaced the contactor with no luck still. When we try to drive it the wheels wont move. I've lifted it in the air and nothing changes.

Im curious what part could be changed in the handle that could be causing this issue.
