Hello I would appreciate some feedback on proper ways to test a no start on a Ford 3600. I was using the tractor, turned it off came back a few mins later and nothing. Some times the safety switch would act up and I'd have to reseat the wires and it would fire up.
I'm about to split the tractor for a clutch swap and will replace it then.
Please give me your thoughts on this.
Battery has ~13v
I cut the Neutral safety connectors off to eliminate- ( I believe to bypass you should cross those together, so I wire nutted them)
With the Key turned on and safety switch wires nutted together I show ~12.5 volts at the starter solenoid. If I turn the key voltage drops to 0 and starter does not engage.
What I find strange is this. If I open the 2 safety switch wires, when I turn the key voltage stays at 12.5v at the solenoid but still the starter does not engage.
Should I have the safety wire connected together or should they be open to work (this is just temporary for testing)? The 2 wires that go to safety switch go up in the column and I'm not sure where they go I'm wondering if there is not an issue further up their "path". And that is not letting voltage got to the starter or if its actually the solenoid
I believe next step is I should try and bypass the solenoid by crossing out the 2 wires that go from solenoid to the starter and applying 12v directly to it from an outside source. The start should engage then correct?

Today's Featured Article - New Hitches For Your Old Tractor - by Chris Pratt. For this article, we are going to make the irrational and unlikely assumption that you purchased an older tractor that is in tip top shape and needs no immediate repairs other than an oil change and a good bath. To the newcomer planning to restore the machine, this means you have everything you need for the moment (something to sit in the shop and just look at for awhile while you read the books). To the newcomer that wants to get out and use the machine for field work, you may have already hit a major roadblock. That is the dreaded "proprietary hitch". With the exception of the
