horn air compressor

[uemjg]

I'm trying to power my 12 volt air horn and can't find a 12 volt spot to connect.  This is a 75 MCI-8.

Or am i better off getting a 24 volt air compressor?

Suggestions?

If you have 2 - 8D batteries, or other combination of 12 volt batteries to make 24 v, take a line from the connecting wire that goes between the battery/ies.

The connecting wire will be the one that goes from the positive of the battery/ies whose negative connects to the frame, to the negative of the other battery/ies. That point will give you 12 Volts positive to your compressor.

The negative wire from your compressor will then connect to the frame.

There is a 12 volt connection at rear panel I don't know about the front maybe the MCI guys know for sure but I think it is 55 or 58

good luck

The mc8 had a 12 volt option which included a 12 volt lug at the front panel, AC panel, and rear panel. Stud 55 in the front, stud 6 in the AC panel and stud 41 in the rear. All on circuit #23.

It sounds to me like you're trying to use an air horn with its' own air compressor.  Why do that when your bus has its' own air supply.  Just buy either a 12v or 24v air solenoid and hook into the buses air system.  Good Luck, TomC
