Hi, I have a strange issue with our GPW series walkie. Was working fine until the other day the operator said that it would drive forward and reverse but would not lift. I confirmed, and started troubleshooting. Found a broken wire to a limit switch, which I assumed was the problem. I repaired the connection and still had no lift.

I ordered a service manual which won't be delivered for a few days. I was able to obtain a schematic and I was checking things over visually. Thought I would give it another try, plugged the battery back in and lift worked fine up and down but now no drive forward or reverse. No contactor engagement at all.

Thought maybe a short, but can't find anything obvious. Fuses good. It seems that when I connect the battery, EITHER the drive or the lift will work but not both. At one point another person was looking at it and said that reverse was working but no forward (but I can't reproduce)

I tried messing with the handle while trying to lift/drive but nothing strange it seems to be working as it should.

Any Ideas? I'm stumped!
Thanks!
