Yes. That switched voltage seems to be there according to the voltmeter, on my truck. FYI, my wipers have been parking perfectly for 6 months now. If there's work involved I firmly believe in "if it ain't broke, don't fix it".

What is the condition of the batteries? Older batteries with higher resistance cells do not load an alternator much and can allow the voltage to drift high. The alternator and regulator may be ok. Measure the voltage across the two batteries. If either measures over about 14.5, and they are...

Maybe some follow up is needed on this issue to keep someone from running their truck off a mountain? I know for sure that if air is put in the Emergency/red glad hand UP FRONT, as for towing, the parking brake is released and the truck will roll. The brake system then awaits pressure input...

With the manual trans you could always bump start it.

Thanks everyone for the feedback. Wes, you did the right thing on that water pump, which is now off. It is as rough as any bearing I ever heard! After careful consideration of the work needed to drive the truck to the shop, like adding water, putting batteries in only to have to disconnect...

Observe that many of the cheaply sold auction LMTV's look like good deals at first until you run into a problem with engine, transmission, drive train, electrical system, or other major dollar drain. Maintaining a big truck takes inventory in big tools too. There's a logical reason that...

I want to move an LMTV on which the water pump is not turning (bad bearing and the belt is off). It will have coolant in it, just no circulation. Previous owner had been driving with the belt on with no over-heating, but with high risk of shaft failure. The truck needs to move to my shop...

That larger box looks like an older version of a Newmar DC to DC converter (but could be a Wilmore). 24 volts in gets you 12 v out. Agree that the little box looks like a battery maintainer. If that's what they are, both have a place on a HMMWV. [edit: I should have said "have a use"...

Excellent video and well presented! Thanks.

Wes is the Energizer Bunny of MV's. He even made time to evaluate, load, and haul an LMTV for me yesterday. Thanks Wes!! Great job! Bob

Zacktenn, KMVC is camping out this weekend at Frozen Head State Park near Wartburg. We'll be there around noon on Friday in campsites 18 and 19. Come on out and visit with us, MV or no MV. Other MV enthusiasts are invited too! Bob

That engine sure has nice big jugs!

Hi Wes, how is your engine rebuild going? Do you have your truck back to Memphis yet? What an ordeal.

The material in that elbow looks like a sintered metal filter, basically a bunch of metallic balls fused together with air passing through the interstitial spaces. You might try soaking it in various solvents. If it is a filter, IMHO it's a poor design, designed for low volume. There is not...

In addition to just voltage measurement, for the health of the batteries they should be charged fully, based on Amp-hours. You didn't say if you have a "smart charger" capable of high amperage or just a simple trickle charger with just a few amps. I only mention this because a little trickle...

Your batteries are not charged according to the voltages. You should see over 24v and over 12v WITH a light load. It still 'clicks', right? Measure the voltages while trying to start the engine. You need to evaluate the batteries, or the charger.

A slipping pump belt can severely limit pressure, and you'll never know it. On civilian 406 mogs it's common to find an SAE belt on the hydraulic pump, non-metric, and its a non-fit. A visual check: If the belt is buried in the v-pulley, it is either worn out or the wrong size. The correct...

A flow control valve is not like an orifice that works both ways. It acts as a check valve, with free flow in one direction but restricted flow in the reverse direction. Some are fixed flow, others are adjustable, and this looks like a fixed type. What rpm are you running when the hydro...

Could it be a check or restrictor valve in a return line? Purpose could be to stop bucket from falling immediately in float? Keeps bucket under control?
