The solarizer/pulsetech is not really a charger, but a desulfator. It doesn't put out enough juice to charge the battery. It sends high frequency pulses (PWM) to the battery to prevent sulfation. That's it. It is normally 'on' at all times, even when engine is running, so no issues. SLA...

OK, even if they're 250AH, they're still only gonna be rated to 50% DoD (Depth of Discharge) for full life. Most are rated at 80% DoD MAX, but at significantly lower life. In addition, Lifepo4 have cycle lives in the 3000-5000 range, whereas AGMs are only rated for ~1K cycles MAX with most...

No it doesn't. 4D is generally 200AH, not 250... AND....only half of that is usable.. AND..... AGMs are on par, price-wise, with LiFePo4. AND.... 2x 4Ds weigh ~234lbs for 200AH usable.. AND.... 2x Lifepo4 weigh ~48lbs for 200AH usable.. AND...Lifepo4 can recharge quicker..

Who said anything about battleborn? They're overpriced. Right now, LifePo4 batteries are going for less than $300 for 12V@100AH, 200AH 24VDC rack mounts with all the bells and whistles are going for ~$1200 --- https://www.amazon.com/dp/B094NN5KWY ^^ $240 - $12 coupon = $228 Can support up to...

I ran through all this years ago. Keep it 24V - You can charge from the alternator. Skip the DIY liFepo4 - commercial systems are dirt cheap these days. Whether you go rackmount or decided to series/parallel 12V batteries, the minimal cost savings doing it yourself isn't worth it. Get a 24V...

I know you said you fixed it, but double check that your button on your transfer case lever isn't stuck in. Shoot some electrical contact cleaner in there and actuate it a bunch of times to help clear out anything that may be causing it to stick.

Biocide is a thing ;) I use PowerService Bio-Kleen.

Went to open my door and heard a bunch of metal parts drop and my door handle didn't work. Opened it up, and found the spring on the latching mechanism decided it didn't want to live anymore. Ordered a new latch. Installed it... and handle wouldn't go back in. Pulled it back out... checked...

You need a better antenna. Go with a 1/4 wave.. you'll thank me.

While it may not be an issue for others (or the OP), for security reasons, I want something that can be retracted/stowed from inside. With my M934 I wrapped a loop of paracord around the top step, and once I was in, was able to lift it up and bring it inside. I'm more concerned about 2 legged...

Found them! 'Pipe plug socket' https://www.amazon.com/dp/B09F64XLCW

Accordion stairs, as some call them. I'm just gonna go ghetto and weld up a hinge on a heavy duty aluminum staircase. It'll fold up/down when not in use. Tempted on whether or not I make it spring loaded so it only stays down when there's weight on it... :D

Also, ABS light was still on. Apparently, it just needed to be driven. I moved it about 200ft..Turned it off. Went to move it about 20 mins later, and power switch on and *clicclicclick...clacclacclack*......... *click*..... ABS light off... :cool: I'm guessing you're supposed to go into...

I would caution against any overhang, personally. Overhangs greatly impact turning ability and can negatively impact departure angles. I did all the maths for the 939 series in its different flavors (923, 931, and 934), and not in one case did the extra length offset the negatives involved (in...

If you have dimensions of the bed, you can use that as a starting point.

The stock alternator is overkill to just run the truck. No one needs to upgrade unless they have a specific use case.

So, the programming sheet doesn't seem to work.... but here it is. I might have to suck it up and email HALDEX. EDIT: Site seems to be shrinking my images to make them unreadable. 2 full size versions below.

The thing about 24V is it's half amperage compared to 12V. So a 70A 24V alternator is akin to a 140A 12V alternator. Watts are watts. With these trucks, the only real electronic draw is your lights, ABS, and the fuel shutoff solenoid (and the starter). The solenoid can be bypassed, so these...

Side note: DON'T use 'CLEAR CC' - only 'CLEAR CA'... Apparently 'CLEAR CC' clears the calibration.... and you have to reprogram it. Luckily, mine came with a programming table sheet. I'll have to take a pic of that and upload it.
