A couple days ago the lift function stopped working, spent some time playing with it and after moving it around under its own power a couple times then forward / reverse stopped working, not even a clicking noise.
Fixed the lift function by unplugging the battery, letting it sit and plugging it back in. After that I started poking around and found that the forward / reverse contactors were not pulling in, found a special little 5 amp fuse in the black box circuit board, replaced it then they pull in and out however the main contactor to ground them doesn't. I played with the wiring quite a bit and really had very little luck, even with a signal transducer its hard to tell because so many wires tie together. I am really in need of an accurate wiring diagram / or trouble shooting manual. I would be more then happy to pay $25 via cash app or paypal for someone getting me it.
