Recently acquired forklift that needed lots of attention. Hyster H60XM. Perkins diesel engine. Virtually nothing about the engine in the Hyster manuals I have.
Instrument cluster was disintegrating. Steering column covers broken into multiple pieces, some pieces missing. Previous owner had been using a remote starter button to start and pulling the fuel solenoid connector apart to stop it.
Replaced the cluster and covers. Starts and stops with key.
Decided to change water separator filter. Took forever to find priming lever underneath accumulated crud and get injector pump primed.. Ran just fine for a few days.
Then....... start up cold and after a few minutes of idling to warm it up, it would either die(restart, no problem) or almost die.
Latest behavior, start, do whatever, shut off. Will not restart.
Fuses not blown. Fuel solenoid doesn't click .
Three wires to solenoid: red 12vdc, white and black wires seem to be connected internally. 026 ohms between red and white/black wires.
New solenoid. Plunger is spring loaded to extend when un-powered. I assume that the injector pump pushes the plunger in and when powered the plunger is forced extended to open up the fuel passage.
Hooking solenoid to power on the bench, I get no response. +12vdc to red terminal, white terminal to minus of power supply, black terminal open/to minus/to ground. None of the combinations get any response from solenoid.
Checked voltage at connector on machine: red to ground=12.5 vdc, Red to black terminal=12.5 vdc, red to white terminal =0vdc.
Do not have wiring diagrams nor have I found any for this machine with Perkins engine.
Got any ideas why new solenoid doesn't seem to function before I try to install it? A real PITA to install. Took over an hour to get the old one out.
