Colt Case Ingersoll Garden Tractors

I'm sure this question has been asked 100 times. I tried searching past posts, but didn't get far. I have several 'official' wiring diagrams but I have a problem with following wires when they run several inside a tube and are numbered. I need a hand drawn diagram with colors listed, of the switch and regulator. Anyone ever post such a thing ?? I cannot see where the 12v comes from, to get to the switch. MY solenoid not energizing by key. And I have temporarily put a ground jumper on it. ( neutral grounding is defective) Thank you.

I’m sorry I don’t have a diagram to share, but was thinking, would a continuity light help trace the wiring?

I don't know how much you could trust a wiring diagram with coloured wires. The wires in your tractor might have been changed. Like Jeff said, it wouldn't be that hard to figure out where each wire goes with a continuity meter.

Our 4018 started blowing the 30 amp fuse last night. This started me thinking about how to tackle your problem and maybe yours. Instead of a wiring diagram like our manuals have, a ladder diagram might be easier for a novice to follow. @ckainMich What is the serial number on your tractor?

Good point. With the right diagram we can figure out a way to chase each wire for its purpose.

I took a look at the 442 manual. It has been 20 years since doing ladders. Ladder diagrams are a weekly encouter in my line of work.. This morning memories of an old software program came back. A copy of it should still be around that would simplify and make the ladder diagram easier to layout.

I had to look up the term ladder diagram, as I didn't know exactly what it was. Thanks for overloading my brain @Spike188 !

Spike, I can do well with a 'real' schematic or ladder dia. I was trained in electronics in USAF. Many years ago.lol
My serial on the 442 is 9332595.

The day job is hitting me hard right now. Don't give up on me.

Trying to help. Look at this diagram, do to have these components? I'll try to find a better one.
