Is a M916 12 or 24 volt? The batteries are hooked up 24 volt and it has a slave connection.But I thought I read it was 12 volt.

Both. Starter is 24V, rest of the electrical system is 12V. The alternator produces 12V and has a second rectifier for 24 V. Also has a 24V circuit to power tactical trailers.

The M915 ,M916, and the M920 are 24v systems and they have 12v and 24v pig tails for trailers

So are the trucks lights 12 or 24 volt ? I want to hook up a 12v brake controller.

The manual shows that its primarly a 12V system, But uses 24v for starting. It also states that there is 2 cables for trailers that are normally stored under the passanger seat. 1 is for a standard 12v trailer , the other is for a military 24v trailer. so I would say hooking up a brake controller is very doable.So from there discription I would say there lighting is 12V but you could use a meter to double check.

Quick look at tpub shows this simple diagram.
ELECTRICAL SYSTEM
Not sure how much real charging it can do for 24v, but with a battery equalizer as part of the system, I imagine the alternator doesn't put out a lot of 24v.
Seems like doing the 12v electrical hookups should be pretty easy though.

There are 2 sockets on the bottom of the winch, driver's side. One is a 24v mil plug socket, the other is a 12v std socket.

The lighting system is 12 volt, as should everything be in the fuse panel on the dash.

the alternator puts out something like 90 amps 12v only, that is scaled down through a rectifier to 32 amps 24v part of the truck is on 12v most of it on 24v. I would double check the headlights I do believe that all lighting, guages, cigarette lighter etc are all 24v. afaik the only thing 12v is the trailer circuit for powering a civi trailer.

Just to clerify,all lights on the 915's through 920's are 12 volt. The only things that are 24 volts are the starter,heaters for the cat trans, and military trailer wiring. Like was said earlier,the alternator is a 12 volt alternator with a rectifier for 24 volts that keeps the top side batteries charged. The link above is for the A4 version with a battery equalizer. Early trucks didn't have these. Hope this helps.
