M1088A1 missing part

[Dmorris]

Picked up a M1088A1 with a C7 motor and I’m having all kinds of electrical issues and missing parts one part I’m missing is a shunt that comes off the main harness from the cab going to the alternator, batteries etc and I believe it’s the source of my electrical issues anyone have any leads on where I might fight or get one?

Not clear to me what components you are talking about.

Moved your thread to the right forum. Now if this is a thread about fixing things, it is in the right spot. If you want to buy things, it needs to be in the "Parts Wanted" forum. Or you could start a "Parts Wanted" thread and keep this for your on going project.

no sir, I’m getting 12v to the fuse panel only no 24v. schematic shows everything leading to this shunt posted in the picture but I’m missing the shunt did not come with so I have no part number. From the

No sir only a wiring schematic, no parts book. I picked the M1088A1 up as is. The cable coming from the battery were a mess I believe I now have them wired correctly based on the wiring schematic but from the batteries the cables lead to a Shunt as seen in the image. I do not have this shunt someone clearly pulled it and it didn’t come with the M1. I’ve since tried bypassing the shunt and I’m getting power to the cab but only 12v not both 12 & 24v i think not having this shunt is screwing me up somehow.

The TM you need, but is not released to the public is TM 9-2320-392-24P.
I looked at the TM for the M1088, (Basic model) and found the starter shunt.
TM 9-2320-366-24P

Item # 7

Part # 12258937-1

I think its what you want. But you need to look.

Ok, first off that pic you posted of a shunt is from an A0 schematic... as far as I am aware they did not use one on the A1's... a shunt is used to measure current flow, and on the A0 it was in the ground path. Its output only fed the STE test plug...

Battery ground should go direct to starter motor housing, with a braided strap connecting it to drivers frame rail.

Batt +12 goes thru manual disconect, remote disconect and to LBCD 12v battery terminal. Alternator 12v cable is also connected there.

Batt +24v goes thru manual and rem dusconnects and to 24v batt terminsl.on lbcd, 24v alt is connevted there also.

The 12 and 24v load terminals on the lbcd feed to.the cab...

No shunt on a C7 truck. Can confirm.
