There is a set here under present conflict vehicles. It is just the schematic and located near the A0 manuals...

Yep, battery tester. On wet cell batteries, you removed the caps on the compartments/cells and inserted it to measure the electrolyte level. If the tip contacted electrolyte, the led would light indicating the cell was sufficiently full of electrolyte… unusable on sealed batteries…

You only need one balancer, even with 4 batteries, as the two series strings are wired in parallel, and parallel batteries are already hardwired to balance:) a single balance will balance the 0-12 to the 12-24 batteries(or vis versa). But you still need a source of power to replace that lost...

No, the 1 and 2 indicate battery 1(gnd to 12v) and battery 2(12v-24v). In your pic the outermost batts are grnd-12v(batt 1 in my diag). The innermost are 12-24v (batt 2). The connections near frame are 24v. One to the starter, one to the 24v batt term on the polarity box and one to the nato...

Here, I condensed the important bits out of the mil schematics for the A0 start circuit. you will need this eventually, everybody does:)

Drop to two batteries, your very expensive alt will thank you. The truck doesn’t need 4, and the alternator is really undersized in the dual volt configuration to charge them properly. CB79 feeds 24v IGN power to the TCU. Yours could be either wtec2 or 3 TCU. A 2 has a wider green LED...

No trans display, no neutral start circuit. As mentioned clean the polarity box connections and shunt connections between spare and air filter. CB 79 should power the trans controller, but it also gets 12v from another breaker(will have to.look it up). Ypu need those to power the trans which...

The rad can pull in a lot of air down below on either side. Here is a pic of the .mil version, like a diaper that bridges and seals that space between intercooler and rad. kind of a pain to install from what I understand… i was thinking a set of tracks on either side of the rad face so I...

Yea a large chunk of the lmtv radiator air comes up from the lower bumper area...

Yea, whats it look like installed/where does it set?

What general said. S5 connects it to sensor - on the ECU…

So have you ordered your 24v alt and 24-12V converter yet? Now is the time to convert:)

Not quite. That 100AH rating was for a 20 hour discharge rate(they do other ratings like 5 and 10 hours, but a 20 hour rate is the norm), so for a 100AH battery that is a 5A Load. As you increase the load above that 20 hour rate, the battery drops in efficiency. Basically the added current...

Ok, so my first description was correct. When you push in the park control you send park air thru a 2way(behind drivers grill) and on to the anti-compounding valve that in turn sends air to compress the park springs/release the park brakes. Watch that video I linked to and you will get an...

Wait a minute, release which brakes? release park brake or release brake pedal? I think I may have misread your initial post… i thought you had determined that the air was COMING FROM THE FRONT GLADHANDS… The vent for the treadle valve(brake pedal actuates treadle valve) is directly above...

A 2way checkvalve has 2 inputs and a single output. Whichever input is greater slides the core out of the way and feeds the output. your issue is the top 2way checkvalve under the drivers floor(behind the grill). When you release the brakes, you APPLY park air to one side of that 2way. The...

Thats weird. I am thinking you had something else going on. Dropping power should not be catastrophic for the transmission. It directs hydraulic pressure to clutches with electric power to solenoid valves. When you drop power, these valve stop sending fluid to clutches. no clutches, no...

Batt voltage to gauge capacity is only good after the batteries are stabilized, so it is not particularly useful when a load is applied… y0u need to let the batteries set 30 minutes unloaded to allow the electrolyte to equalize somewhat, for that volt to state of charge table to be applicable…

It probably depends more on your charging capability with only 30 miles, perhaps an hour driving total? With 4 decent batteries, charged, you should have 240AH. The total lighting load is ~25A@12. Thats double the standard 20 hour rate(12A) that the 240AH rate was determined at, so peukert...

What General said, wouldn't really effect freq, just suppress/average the signal amp;itude(turn AC into DC). Way back when, it was common to pull the tachometer signal from the alternator, but those signal points were designed for that. As mentioned, Neihoff intended this output for a specific...
