Was in the electric panel under the driver window with the bus running and touched a wire to the REI radio system amp to supply a voltage to see if it still worked and spark-poof-silence! The bus shut off and now the whole thing is dead as a door nail. I had no idea a single small  spark could wipe out the whole bus!
 Don't even know where to start.

Having recovered from the initial shock and probed a bit further it seems everything works that would work without the ignition switch being on but everything that relies  on the ignition is dead. Ideas?

Ill guess: inline fuse to DDEC off battery  look for inline fuse holder in front elect compartment or battery compartment.    Maybe BK will chime in I think he had problem some years ago.  Bob

You got to get out your manual and look for fuses.

You should have 12 volt feed going from switch back to ddec. on my 89 prevost there was a inline fuse in the front elect compartment after the ign switch.  Some have a 12 volt selonoid (sp) activated by ign switch.  Get your volt meter out.  Some had a inline fuse rite at battery tap (12 volt)  all possibilities.  I don't have a manual for your coach. Hopefully a MCI guy will chime in.  My last MCI was mechanical.   Bob

DDEC = Detroit Diesel Engine/Electronic Control. Perhaps you should add your engine type to you signature information. Then we will all know you do not have DDEC.

Just saying ...

Same general idea if it has a electric fuel shut off. Was assumed that most Mci had detroit and that year DDEC.  Good luck!  Bob

Update! The Po connected the radio cutoff switch to the master control breaker. We fried the breaker when we shorted the radio controller. Moved the master control wiring to an empty breaker and she started right up.

Chazwood:

Glad to hear you got it up and running! What part of the galaxy is home base?

How do you like that Cummins L-10? How does it do on fuel economy? A lot of the older buses here in Mexico that came with 8V71 or 6V92TA Detroits were upgraded with the Cummins L-10.
