I think you need to be more specific as to what problems you are facing. You need an MC-5 Maintenance Manual. In it are the various electrical schematics. Then go to work on the rear junction panel with a micrometer and a continuity tester. The 5's were/are great buses...gl

You can order your Manuals here.  You should keep a set in the bus anyway.  Having them in the bus if you break down whilst on the road can save you a ton of money and time, so a mechanic does not have to figure out what is going on without the manual for your bus. They will have a wiring diagram in the manual too.

I carry a set in mine, but I have an Eagle and they seldom break down, so they still look like brand new.  ;D ;D ;D
