Hello, first time actually posting something on the forums. Hyster h90 XM, brake cut-out switch is not the problem shift lever forward and reverse switch is not the problem, transmission mechanically sound, I can put 12 volts to the solenoid and get it to move forward or backward depending on which solenoid I have 12vdc to. I see no wiring issues, I noticed there is a black box on what would be the firewall, is that a transmission controller? Would that be my issue? it's the only thing I can think of. When I go into forward or reverse the machine beeps at me not the same beep as the E brake handle being down or not up, not a seat switch issue either, actually beeps continuously not a single beep but on off on off. Any help would be very appreciated.
