Is anyone interested in coming to watch me melt this forklift into a puddle of smoking waste with a large amount of Thermite?

Because i'm beginning to think that is the next logical step in this troubleshoot effort.

Seriously, I have wasted so much time and money on this its not funny. I have hired 4 local techs no results, I have spent over 100 hours looking at it no results. I have replaced practically every electrical/electronic component on the lift.

Everyone says its the contactors. I tested all of the contactors. When that did'nt work I replaced them

I replaced the three circuit boards
I replaced all 6 of the transistor modules on the back panel

The only thing that I can find to make it stop showing the C0 error is to unplug power from the board.

I dont know I might just try to cut the thing up into little pieces with my plasma cutter.
