John Deere 318 Starter Won't Engage
I have a 1989 John Deere 318 with an Onan P218G engine and a John Deere AM107421 voltage boost relay installed. The tractor has been starting fine for years. Today when I turned the key, nothing. No starter response at all. Have geed battery voltage, even tried a booster, no difference. Two lights on dashboard are lit, shift is firmly in neutral, parking brake is set, I'm sitting on the seat, turn the key and nothing. Possible the hard starting relay failed? Bad safety switch on the seat or shift? Is there a way to bypass the safety circuit to test it? Any help would be greatly appreciated.
