I bought a cheap HMMWV at GovPlanet auction and it's already broken!

In this video I go pickup a 2006 American General HMMWV that I bought almost 2 months prior. The paperwork on these things can take A LONG time to process.
After retrieving the HMMWV we drive it around and assess how good of a purchase I have made. Then we try to diagnose an overcharging situation that started the batteries on fire!
Help me decide what to do with this cheap military grade off road unit next!

Enjoy the trouble shooting side. It’s awsome to have you guys thinking out loud as I’m trying to figure it out also. 💪

Talk to the car wizard, he worked on those when he was in the service.

Solid purchase!! I enjoyed my hummers while in the military, they were absolutely a beast of a vehicle.

Get the GCI brand "CARC substitute" tan. Its the proper color to match.

Cool buy. Can't wait to see how it goes. You got it right the square box is the regulator. You have a 200 amp neihoff generator. If i saw correctly, fix the plug connections on the rear of box and i didn't see the big grounding strap either. Should be on attached to the side of the generator to the motor, it's like an inch wide. Looking forward to seeing more hmmwv.

Hello for Emporia Kansas, I would like to see more on this hum v.

Imagine that... An Ex-military vehicle without regulation... Such a cool vehicle!

those are tough trucks, i like them a lot. I hope to own one, one day

They are a competent off road machine with very little investment. We love to run ours off road here in Alaska. My 1988 is the three speed and 6.2. Does okay for what we use it for. Mountain passes are tough on the highway. Mac Motors and Mid West Military Equipment can fix you up.

Surprising to hear about the turbo truck. They seem a dime a dozen right now

I'm a lttle late to the party but since you are part of the Hoovie, JR crowd then a good expert is the Car Wizard - he worked on Hummer's and Tanks in the Army!

I see Geoshield boxes in the background. You tint windows too?
-
There used to be a voltage regulator under the dash (drivers side) that you could adjust with a screwdriver; this was back in the 90s so I'm not sure it's the same.
-
Did you get it titled and tagged for on road use here in Kansas?
-
The body is grounded so can't touch any power wires on that metal box. Ask me how I know. My ratchet has a few burn spots

Swap to a 24v alternator and run an orion 24v/12v converter. The regulators aren't cheap, for the 12v side, if you're putting out over 28v, the gens likely bad and 26v is too low for charging. The older 60a gens didn't have a regulator because they put out the 28v, not the regulator, mainly for the 4spd tcm. You can also get turbo's all day long, bought mine from Albany. I'm about to buy another, some yards are more national guard which are older na units.

you know the answer, read the TM!

Nice squarebody - also, somewhere in this world are a LOT of HMMWV doors lol. Mine also is missing two! So random, I don’t know why they took so many off
-
When you disconnect the regulator now it’s only running off the battery and it will slowly drain them if the voltage gauge was in the green that means the regulator was working if it’s in the middle it’s drawing the battery
-
Too bad YT recommends channels a little too late. Check your grounds especially on the generator. Check the regulator as well, it controls the 24 volt side as well.
