I have a Unicarrier forklift M#MCP1F2A25LV S# CP1F2-9W2945 with 4800 hours. This forklift worked fine Friday and Monday it won't turn over. I can bypass the start circuit and it will start and run, but won't allow hydraulics or drive. A troubleshooting chart or suggestions would be greatly appreciated. Thanks

I've checked all the fuses, connections at battery, and vcm.
