M1151/1152/1165 12v - Where is it?

[Mainsail]

OK, so the big alternators have a 12v output, but where physically is there 12v inside the cab? Is there a line to the battery box somewhere?

14 v tap is on 200 or 400 amp alt. regulator.
The wire runs to the rear battery +.

My 1165 and 1152 have a 12 volt cigarette lighter style plug near the commander's seat.

12V should go from the regulator to the rear battery, then from the rear battery to the TCM.
I wasn't aware of any 12V sources inside the cab area that are OEM, but I also don't have much experience with the newer trucks.

I think someone added that to charge Thier phone.

I'm pretty sure they were factory. Different trucks, different years, different models - identical military 12 volt plugs. With the same type of connector cover as on the STE-ICE cover.

There was a company I found that was using the same style housings for the STE/ICE and putting in a standard car socket or a standard USB charger socket. (How standard? It was the same size sockets you can buy on ebay for a few dollars, only the housing was a bit unique.)

I'm not saying that is what it is in this case, but don't let the housing fool you into believe it is real (or not). You'd need to identify if there is an NSN / CAGE on the part and see if it was something orderable or not.

Even though I already had the seat off for something else I'm not that motivated to stick my head over the batteries and find out!

Hello all
310000+ serial number M1165A1 ECV
1 - Would like input on best place to pull 12/14V from for powering reverse switch on shifter?
2 - Location to pull power for any other auxiliary 12/14V needs?
3 - Removed the 400A alternator and put in 200A Niehoff alternator - I removed the positive cable feeding from the back of the 400A to the starter stud.
The negative I am considering leaving it in place as a supplementary ground (attached/on top of braided ground strap on alternator and terminates on a stud on exterior of the battery box underneath the truck) - is there anything wrong with leaving it in place?

Hi SoCalMarine

There should be a 12 volt output on your 200 amp Niehoff. That's the best place to grab 12v power. (Although not sure what you intend when you say "powering reverse shift on shifter.)

And I left that ground in place when I switched my 400A to 200A also, it proved useful later to ground my aftermarket winch assembly.

 

[Retiredwarhorses]

Nothig should be “grabbed“ from the 200amp, pull your 12v load either off the rear battery and fuse what ever your taking, or the factory Has already provided you the means for both 12 and 24v on the accessories panal behind the battery box with fuses that are waiting for you.
The need for 12v support is not new to the military, it’s been incorporated into the design starting with the ECV.
