Dear knowledgeable mechanics. I could really use some assistance with my compact Excavator. I have gone through about the entire electrical system trying to find the issue. The symptoms began as intermittent starting. Then the glow plugs and engine stopped turning over. Then I lost all ignition and instrument power completely. Things I have replaced that have not solved the problem: Starter, Fuel Solenoid, Fuel Solenoid Harness, Fuse Box, Fuses, Relays, Ignition switch, arm rest sensor. The only things I have not ruled out is a bad ground or the alternator. The biggest clue I have is this: I have voltage at the ignition, I also have continuity from ignition to the fuel solenoid. The fuel solenoid is confirmed to function, but when I turn the ignition on, the fuel solenoid does not energize like it normally does. Testing the voltage at the ignition, I am getting 12v on all 3 poles on the ignition switch with it turned off. When I turn the ignition on, my voltage drops to 0v on all 3 poles and from the ignition power itself. I confirmed the ignition is wired correctly and functioning properly as a switch.
