1987 Comanche Electrical Troubleshooting manual (full)


Recommended Posts

I haven't found this anywhere on the forum, so if it is already here, feel free to delete this post.

 

I hope this information will come in handy to someone else. I bought it to help out with any electrical wiring issues I come across as I am fixing my 87. If there are any issues with any of the diagrams, please let me know. The pictures are all clear on my end, and the words are legible.

1987 includes the Engine and Fuel Controls for the diesel. Plus other diesel stuff.

 

You didn't add it again. Your 1987 electrical manual has new information in it. NOTE: 4.0L engine control has no ballast, no O2 sensor WOT bypass, plus diesel stuff. Should be saved somewhere for easy access.
