Hi my name is***** will be glad to try to help. If all your fuses have been tested with a test light on both sides for power ( Not just a visual inspection) with the IGN in the on position then check all your relays, Test your battery with a digital tester for its internal condition. If OK check, clean, tighten all battery to starter connections including all grounds. Please confirm if you mean there is no BAT power to the IGN switch or if you mean there is no power out of the switch in the cranking position. If there is power in but not out you have a failed IGN switch. Let me know

I do not have BAT voltage at key switch. I am a Field Mechanic for 20 years but not an expert on New Holland Schematics to trace where ign wire at key switch gets its voltage, without a schematic.
Oh and yes for 5 hrs been diagnosing the simple steps.

Hi Chris, Thanks for the update. If I had the schematics for this model I would definitely share them with you/ I did locate a PDF version service book with all that information in it for under $40.00. Click on this link.
