M52A2 Wiring detail

[ww2mbjeep]

I've installed a replacement wiring harnass in my M52a2 and need help. The fuel transfer pump in on circuit 78, how and where does this circuit get power? What is the circuit number that provides the power?

I think I have a wiring diagram for the M52A2. I'm heading to work now - will check when I get home (1:00am central) to see if anyone else has provided it to you. If not, I'll try to find it and get you the info.

I have tried looking on here and on line but the best I could come up with is a M35A2 wiring diagram and guess on the other stuff that is specific to a 5 ton. On your fuel transfer pump wire, I don't know, sorry.

The M39 series tech manuals are kinda lacking in the schematics.

I got the M35 schematic, it helps on most circuits but not the transfer pump.

I haven't been able to locate the schematic. I will keep looking.

If you have the complete wiring with the numbers to the wiring it worth its weight in gold. Nobody seams to have it, I mean nobody.
I'm rewired a m52a1 using a m35 wiring diagram and I know the wiring under the dash isn't right.
If you have the hole wiring diagram for the m39 series 5 ton I sure would like one myself .

Guner51, can you help me with the circuit 78 question? I need to know how the transfer pump switch gets its power? Also, Kenny from Houston is changing harness's for his 52A2, maybe he will one day have a diagram?

If it's anything like my 5-ton, the power is supplied via #27 from the master switch to the selector switch for either left (#77) or right (#7 tank fuel pump. #79 is the ground return from the tank(s).

on the m52a1/a2 and m51 a1/a2, the fuel is drawn for running from the left tank only, the right tank feeds the left tank by a transfer pump. this pump is the same one that is the fuel pump for the 109 box fuel heaters

I just went though all the -211 TMs that I could find ( 8 ) looking for a wiring schematic, non found ????? strange, any suggestions

I found the gas wire schematic in the -211-20-2-2 manual, I'm looking for the wire schematic for the diesel...

View Attached, any help finding the other wire diagram would be appreciated!

I have looked through every 5 ton manual (about 3 dozen) that I have and I am sorry to say no soap. The oldest manual is dated 1972, the newest is 2001.
Sorry that I could not help this time.
If you can find a TM manual #, I will recheck for you.
Thanks, Pvt. Hotdog
