I am in the process of semi-restoring a Mitsubishi MT372 ( as you probably have seen pics here ) and before removing the wiring harness the glow plugs were working fine. I installed a new ignition switch ( 5 prong w/preheat Kubota switch ) and it would turn over but not glow plug. So, I put the old switch back on that worked before ( reason I replaced was that it was sticking in the run position, preheat worked fine ) and now it turns over but no preheat. What could be wrong? I just removed one wire on the glow plug itself and removed the entire harness. Now preheat will not work.
Any ideas?
I checked my wiring diagram and it shows a 4 prong switch but it was wired 5 prong previously and worked fine.
How exactly do glow plugs work and how can you check them at the switch with meter?
What actually causes the dash indicator to glow when preheating?
thanks,
Bill
