Instead of resurrecting a 4 year old thread that has nothing to do with your problem, how about you start a new thread with your problem in the title. please include the year and model truck, and I will be happy to try and help you…

Well the alt really is not in an engine compartment on an LMTV... so even with the batteries remotely located they still see similar ambient temperatures and temp compensation from a regulator sensor is still relevant in a warm climate To help protect the batteries. Thats not an LMTV...

Yea those videos are pretty cool:)

Most alternators have some form of temp compensation built into their regulator circuit. It is not so much about the alt getting too warm as it is about the batteries being overcharged when warm. Most auto applications have the batteries in the engine compartment, so putting the thermal...

None of the trucks came with active suspension. They did some tests with active suspension, but I am not aware of any actually being fielded…

Pretty sure the sensor is in the regulator as there are no wiring shown for a temp sensor between reg and alt chassis on any of the diagrams. The air blower is on the rear. It creates suction and draws air thru the alternator chassis front to rear…

I like Deccas and interstates. The Hawkers are good batteries. If yours loadtest ok I would stick with the best pair of them untill they drop. I should add that the group 31s are not simply plug and play. They are taller and don’t fit as well under the lid with the recesses. Group 27’s will...

As Tomtime mentioned, thats why i asked if you have an oil idiot light. K11 must energize to power the start circuit. But if you jumpered K11 pin 30 to 87 that should have powered the start circuit the same as K11 would… that is of course provided you have a valid circuit. Back to rule one...

I thought this was a starting problem?

There are 2 parts to the K11 circuit. DC voltage applied by K26 and a path to ground provided by the oil pressure switch. Do you have an oil pressure idiot light when you turn on the ignition switch? The same path to ground that allows K11 to energize is also provided to the oil light by the...

I am thinking the air bags were more to compensate all the added weight to maintain ride height on his build… In the end Springs don't necessarily dampen motion energy, they store and release it and some energy is lost in the conversion and release.

Yea, if I read that date code correctly, they were a year old in 2010… They are also AGM’s AGM batteries want 45% of the battery AH rating in amps from the alternator during the major portion of the charge cycle. Plain lead acids want only 25%. So with the 4 battery 240AH AGM bank that was...

On an A0, Yes TPS issues will cause the trans to revert to min/max RPM gear shifting. Its easy enough to check with an ohm meter. It has 3 wires. The outer 2, pins A and C measure across the resistor and should read 9K-15KOhms. the center wire(pinB) varies resistance between either A or C and...

Yes. voltages are referenced to ground so the battery attached to ground must be the lower potential/voltage battery.

It doesn’t really matter, with the jumper, they are basically the same point electrically. I reused one of the original jumpers with a threaded stud on either end. Not sure exactly which end it is connected to right now:) Mine had 2 basket case batteries in it. Put in a pair of group 31’s to...

The normal layout has ground furthest away from the frame, 12v in the middle and 24V closest to the frame. So you would keep one inner and one outer battery. a year old, they may be OK. Fully charge them and let them set overnight and compare voltages. You can also take them to a autoparts...

Yea don’t take anything for granted. I found brake shoes installed backwards…

Runs long enough to get outta my sight, its good to go! One ground goes to the nato plug and the other ground goes to the instrument shunt below the polarity protection device. From the instrument shunt the ground lead continues on to the main ground terminal on the front of the starter...

Unless you like to start like this:) 27F no preheat and my ether line was crimped in a bracket(I thought it was empty, it went clunk but no spray)… A 1500W block heater is nice, I put one in, Half hour or so of preheat and she starts way easier. But if you don’t have the energy source for...

On the back of the hydraulic valve assembly? Thats a vent, and if it is leaking air when the cab suspension air control is on, then you have a leak in that cab air control pushbutton valve. When you turn off the cab air, it closes off the supply air and vents the cab suspension side to...
