I was bored once upon a time and I used some google-fu on the part and cage in the 24P for that spring. It got me to a component at the original manufacturer/provider that appeared to be the correct dimensions. I think they were based out of cali... Unfortunately I did not save that info or a...

I made some assumptions based on the only drawing I have seen that the windings were in parallel, but the idea of them being in series is interesting and makes sense on a couple of levels. Regulate the field current to maintain the desired combined series winding 28V output. Tap the junction...

That is exactly what you should do, except you have to also change the alternator:) I plan on shifting to a straight 24V alt and equalizer if/when my 24/12 alt fails... not necessarilly because of the way the alt works, but because of the VERY high cost of the 24/12 neihoff’s compared to the...

Yep, 12V are more common and less expensive than 24’s, but at least it is better than it used to be 10-12 years ogo... Because of the way they designed the Neihoff alternators, I am really loath to add any additional 12V load, especially considering that is where most of it already is when...

One thing they are touting in their advertisements is the 15KBTU unit, and the other ”commercial” models is that they are built and tested to be more rugged(Shaker table testing). They also make two 12V models(4KBTU and 6.8KBTU) and they are marketing these three units toward the trucking...

You will also need an inverter large enough to deal with it’s startup load, but that shouldn’t be too bad. There was a guy on here a while back selling a rig with an older dometic on the roof powered by inverter.

Don’t think it would hurt, but I also don’t think it would make much difference either. these engines displace 3.3-3.6 liters per revolution. At the flow thru those pipes they don’t have a lot of time to absorb nor shed much heat. I don’t think it would make much difference either way...

Well you wouldn’t need the gen, the DC load for the dometic would be around 65A @24v, which your larger alt could support...

Yep, that is the alt EVERY LMTV should have:) 45A is not a problem for that alt... if you have the generation capacity to support it, for less cost and easier install, you could use a Dometic commercial unit(15,000 BTU) on the roof and add an inverter to power it. This would have the added...

“Power consumption 45 nominal amps @24 Volt DC” That is pretty much all your available 24V alternator output, and at 10,000 BTU output would be running 100% of the time to try and keep up with the heat load... You could do something like this, with greater output, without risking your...

You are looking for P913 behind the heater. Pin 12 has a wire labeled 1550 on it. That is the signal from the ring gear magnetic pickup. It is referenced to ground. Are you putting the tach there above the heater? Because the signal from the pickup first goes over under the drivers dash...

The ABS fault disappearing when CTIS is unplugged indicates to me that it is probably a programming conflict. The CTIS is connected to the ABS, trans and engine controllers via the J1939 and J1587 data busses. I don’t think there is any actual or planned interaction with CTIS, they simply did...

The transmission is a small vampire load on my 12v side. Because of the rest of the configuration, 12v is the last place you want a low battery as it takes a LOT of runtime to recharge it, especially if the lights are on...

That port behind the grill is where the treaddle valve and the park/trailer control valves vent to when they release air. It needs to remain open. If you are venting air continuously from that vent port, one of those 3 valves has failed. From your description It sounds as if you may have a...

manual 20-1 thru 20-5 and 34-1 and 34-2. Go all the way to the back. Then work backwards thru about 10 pages of conversion tables and change forms and you will hit the manuals. There are 43 pages of them. The last 9 pages are air and hydraulic, the first 34 pages are electrical...

Air is only really an issue when it is in a hydraulic pump. In a line or cylinder it simply compresses to whatever the fluid pressure is. Because it acts like a spring, it can add a spongy feel to manual systems and cause erratic operation as the air is allowed to expand. the cab suspension...

When I was just learning the circuits(while waiting to pickup the truck), I sketched them out by hand, which gave me the idea to simply draw an autocad drawing that incorporated my individual system drawings(Start-run, charging, lighting, brakes-signals, inst ect) I could get quite a few of...

You only really need 2. The milspec for the LMTV battery bank was gross overkill. Caterpillar specs a pair of group 31’s for equipment using the 3116/3126 engine (100AH, 1000CCA). The 4pack of 6TL’s originally specced(240AH) is way oversized for the alternator installed and is probably why...

They are in there, after the electrical is the air, then all 3 hydraulic systems, winch, steering and Air Op Pump... Message me with your Email and I can send you a reduced file size .PDF with just the drawings(pages faster on a laptop of tablet).

You can print them from the PDF manuals found here on SS, I printed them out once When I was learning some of the systems. But being in a linear format, they lay out end to end. If printed on 8.5 X 11 letter sized paper the 34 pages of just the electrical portion would be 31’ long... I...
