Hello, I have an IHI 55j2 with an Isuzu 4jb1 engine in it. I'm trying to figure out the proper stop solenoid setup for the machine as I purchased the machine with many missing parts. I bought one of these solenoids off ebay:
It has three wires, and there is a linkage that connects it to the injection pump to stop it. The solenoid pulls in to shut off fuel.
The wiring diagram (attached) for my machine shows the one lead going to ground, one going to B terminal on the ignition switch, and one going to BR terminal on the ignition switch. The only way I managed to get the solenoid to do anything interesting was to connect the blue wire to B, red to BR, black to ground. When BR is 12V, the solenoid would extend. When BR was 0V it would retract. Seems good... except the solenoid was getting extremely hot, and now appears to not be working at all. Not sure if I've wired it incorrectly, or purchased the wrong kind of solenoid? Any insight would be helpful.
