Under the dash left side by the light breakout box is a small box labeled power supply. I always thought it was for the dash dimmer or something. The manuals dont really describe it and even the mil mechs that I have spoken with dont know what it does. Maybe thats the freq divider.

I think the wiring going to the transfer case is for the diff lock. Can you try swapping in a ctis controller from another truck and see what happens? The trans computer uses the vehicle speed sensor on the trans, engine speed sensor on the bellhousing and the throttle position sensor, which is...

Wtec2 has the trans computer behind the keypad and wtec3 has it in the passenger kick panel. I would take the speed sensor off, clean it and put it back on. The wtec2 back plugs on the computer can slip out a bit especially if you have been playing in the dash.

You can replace the terminals in the board. I have replacement clips to hold the terminals in for relays and breakers.

I was thinking about it I had that low speed warning once before when I had a bad speed sensor. Once I replaced the sensor it cleared on its own though after some driving. The speedo was clearly off with the sensor being bad. I wonder if the speed signal goes into the trans ecm and is divided...

I looked on the bay if you search blade fuse breaker there is a wide variety of choices.

Buy all generics they are cheaper and all 5 pin relays. The extra pin wont hurt anything. It should have been like that from the beginning its just one more thing to add to the confusion.

Regardless of 12 or 24 volt and the breaker size if you have a dead short it will trip. There is some leeway in fuse or breaker sizing in the LMTVs. As long as you don't use a breaker with too low of a rating that normal operation causes it to trip.

Curious what model prolink you use at the shop? Does it take a card for the Allison trans? Is there a separate cable for it so you can diag an A1 truck? Or is there a different prolink handheld for the A1? It is possible a wire could have gotten nicked or pinched somewhere during the engine swap...

I have seen similar civilian resettable breakers designed for use in place of blade fuses. I will look around.

A blade fuse works just fine. Just keep a spare on hand since its one use. You can steal a breaker from a less used spot and put the fuse in its place. Will

The ctis relies on the trans speed sensor (shared with the trans ecu) to know what speed the truck is traveling at. At a lower ctis setting you will get an overspeed at a lower speed. Something is making the ctis think the truck is traveling faster than it actually is. Did you check the ctis and...

It stays low because your fan runs all the time. Air keeps the fan off. So you could have no air to the fan clutch. Or it could just be stuck from sitting before you got it. With the truck off and the air drained, take the air line off the fan clutch and hook an air compressor to it. You need...

Same thing

Been running the same thing in my 1078 for some time without incident. Civ cars have the same basic bulb mount with no issues. Fording water it might be possible to get a little into the housing though. If thats a concern then the newer style trucklites work ok but not as bright as the 90w low...

At one time I had 36 mil reman HT740 transmissions. One Red River rebuilt one had some small shop rag pieces in it that caused shifting issues and was found upon disassembly. These were all supposed to be rebuilt and dyno tested to ensure good working parts were sent out into the field.

Just got a pair made by candlepower. ARB makes a nice one I think if I need more I will go with those they have good reviews. I prefer the Hella 12volt 90/100 watt bulbs. Use good ceramic sockets you can crimp the mil packard connectors right onto the leads. Stay away from all the ones made to...

Depends on what cable. There can be several different ones. I have had a lot of trucks that has radios removed before drmo but none with working radios. With the radio relay engaged in theory the main radio power cable should have power I don't see how the intercom would affect it. I would...
