Same basic questions for a no-crank. Which relays in the power panel energize when you turn on the ignition switch? Do you have a low oil idiot light in the dash light panel? Depending on the truck(you didnt say what year and model truck this is) K11 and K24 or K26 must energize when you turn...

The air and hydraulic diagrams are in with/a part of the electrical diagrams...

I always first ask myself, does it really need a connector...

Not necessarilly. The issue is probably the flapper type bypass valve up above where the filter screws in is not sealing. That will keep the primer from lifting fuel, and without a strainer in the tank it is exposed to anything the pickup tube sucks up… found a bug leg or camel hair was...

If You mean studs with nuts as opposed to Allen head machine screws, then yes you have the new model clutch, hub and fan disc.

It is probably fine. If it is clear, it is not emulsified. If it has any water, it will be at the bottom of the containers after setting. You could siphon out of the storage containers careful to not let the pickup tube closer than about 1” to the bottom of the supply container. That 1” of...

Yes, same fluid...

Yea it kinda has to increase power/torque to increase RPM. Power output is a factor of the internal resistance and current flow which builds opposing electromagnetic fields, and the timing of the rotor and stator fields in relation to each other. With a given resistance, doubling the voltage...

What truck is this on? On an A0 CB22 sends 24v thru a 205F normally closed sw to power the solenoid. The solenoid provides air to release the clutch. When the temp goes over 205, the switch opens, solenoid releases the air and the fan engages. The fording sw bypasses the temp sw to feed power...

As long as you only feed 24 to the starter motor and not the rest of the 12v circuitry:)

Breaking the 12 and 24 circuits would be my prefered method... same as they do the manual and remote disconnects on tge A1s

Sort of. If you only disconnect ground you will still have a difference of potential between any 12 and 24 circuits. The polarity protection device prevents any reverse flow from 24 thru any 12v circuits, but if you are working on anything there is still potential present in the circuitry.

There are three 24v leads. One is from the nato plug, one goes to the polarity protection device/alternator and one goes to the starter solenoid. So those 3 leads will need to go to the + terminal of the innermost battery. There is only one 12v lead and it can get connected to either end of...

if it is pulsing one battery, it may be raising and lowering the one battery in relation to the other. The equalizer would see this and might try and equalize to the ever changing conditions. This might stress the equalizer and would most likely blunt/negate any benefit the pulsing might provide…

Yea you can see its 24v counterpart taped over in the upper left behind the innermost hawker. The quick fix to clean this up is get 2 thru-bolt battery terminals for the ground and 24v terminals. Ditch the 4 terminal cable and one of the 2 terminal cables. Use the other 2 terminal cable to...

Well that is all you really need to do to convert to two batts, remove two of the old ones. so yes it looks like they converted to 2 and left 2 of the hawkers in place.

what NDT said, they hooked up a new set in the rear two bays and disconnected the ground and 24v terminals on the hawkers. Just send it:) or pull the hawkers and see if they can be salvaged and insulate the two terminals on that cable that are attached to them…

I am not sure how a pulse maintainer will play with the equalizer. I havebeen using a small equalizer and a simple buck converter supply on a solar panel for a few years now and it worked great. I no longer have a 12v vampire load:(

Negative compensation means it lowers output as temp increases. Hot lead acid batteries absorb energy differently than cold ones. So above 75F it starts to reduce output voltage so as not to overload/overwhelm the batteries and evap electrolyte. Even the cheap smart chargers you buy do this...

No problem, but it is considered poor form to hijack a thread… On the FMTV page you will find a button called “post thread”. Click that, fill in the subject and your question then you will find a “post reply” button at the bottom.
