I'd like to add I do not see a "technical library" here anywhere to search for this info

 

Case Colt Ingersoll Tractors

www.casecoltingersoll.com

There is a technical library section. The parts manuals have electrical layout diagrams in them for your specific PIN of 446. Owner's manuals, if complete, also have a somewhat better electrical circuit diagram.

I bought a tractor that had a mouse chew all the wiring and need help finding the correct wiring diagram. Thanks in advance View attachment 134208

It can be a bit tricky for some PIN's. But this should get you what you need. PDF page 23 (printed page 30)

or this manual....

Yours was one of the last 3 tractors to roll off the 1987 production so likely the later manual I posted earlier would apply. Just let me know if you need more assistance

 

Much appreciated.

 

Jarod, here is a wiring diagram for a late '87/'88 Ingersoll from Operator's Manual 9-9960. It shows the version with the 3 dash lights.

That's perfect. Thank you very much

 

 

Another problem I'm running into is the wires we're completely gone from the back of the ignition switch. What goes where? New switches aren't labeled like the old ones.

 

It's a 5 pin

 

You need a c30530, and the diagram i posted will explain the wiring

 

I would order the pigtail plug and the fuse link and points/condenser

 

Jarod, I have an '87 446 PIN 14112465, so not quite so new as yours. I replaced the ignition switch, 5 pin C30530. Before disconnecting all the wires, I took these pics of the old switch, maybe it will help:

Thanks Bob! That's exactly what I need. Matches perfect. You guys have been a huge help.
