HELP!!! with the electrical on my 1976 mc 8

[reverendken]

The forward luggage area has an A/C box for wiring. It has been taken apart and I am in dire need of a picture of the inside of it.  Any help would be very much appreciated.

Thank
Ken

Perhaps a picture of what you have now would help more.

There is about an 8 stud terminal strip, three breakers that poke out the front of the bux, a heavy bus bar, and two relay/solenoids that control the fam motors.  What has happened to yours?  If your factory AC is gone, probably the relays and the breakers are gone too.  The rest of the wiring is for things like turn signals and such.  The main power feed for the front of the bus comes in on a 1/0 wire from the batteries to the bus bar in that box and goes forward to the bus bar in the front electrical panel.

The box has a panel of 15 studs all disconnected along with 2 stand-off's and a relay, the a/c compressor and condensers are long gone as they were not there when I bought the bus. The condenser area is now the spot where my generator sits. The stand-off's are what I really need to know which one should be connected to what?

On our 8 only the exception for the AC in that box was 4 was left turn,5 was right turn and 13 was for the fuel gauge,the relays were for the high and low on blower fan ours numbered 2 thru 15 ours was a 78 model

Tomorrow I will post a picture of the schematic of the inside of the AC junction box, and a list of all of the stud circuit call-outs.  The two stand-off's appear to be the connections for the front electrical panel circuit breaker.  The two AC motor breakers are fed from the front panel breaker.  But you will see, it is all very clearly drawn out.

Actually I have a better idea.  Go here, get Section 7, look at page 33 and 64.  http://busconversion101.com/mc9_maint_manual.htm

All will be revealed!

Hey Brian thanks for the reference but the mc 8 is different I already have the mc9 stuff and it is only partly the same. I will attempt to use the mc9 info again, maybe I'll get lucky This is just so very frusterating.

Thanks

I have the 8 manual problem is there are 3 different schematics in mine and it may not help you .first is effective with unit 30001 to 30078.second set is unit 30079 to 30650 then unit 30651 forward

If you think one will work I can take a photo and Email it to you, no way can I post it here but I can post it on the MCI group on Facebook if you go there

Sorry, that is the same as in my 1978 schematic for MC-5C, I thought MC-8 would be the same too.
