polarize2For the younger set, no I’m not talking about some dangerous doings in Poland. Jill, the Army Mechanic says, don’t forget to polarize when you hook up your generator and voltage regulator. Failure to do so may lead to damage of either unit (or both)!   What the heck is “polarize” anyway?   Sounds like something you do to get ready to go to either the North or South poles.   Old timers know all about this…trouble is the old timers are dying off.  Good thing they left behind some great old books from WW2 to help us out.



Use a jumper wire.

Polarity. Whenever generator or regulator wires have been disconnected, the generator should be polarized after the units have been reconnected and before the engine is started. If this procedure is not followed, the generator or control box may be severely damaged.

To polarize the generator, place one end of a jumper wire firmly against the armature terminal on the control box and then touch the other end momentarily to the battery terminal of the control box (see drawing above). This sends a surge of battery current through the generator and automatically gives the generator the correct polarity for the battery it is to charge.

As was pointed out to me by Geoff Bull from the G503, the diagram on the right represents the standard jeep voltage regulator and other war-time MVs. The one on left is for other war-time MVs and apparently post-war CJs. The important facts are to verify the markings on your regulator and momentarily touch a wire from “A” (hold on “A”) to “B” (touch wire to terminal). Not all regulators are the same.

You gotta have the right tool!

You gotta have the right tool! Sometimes that’s a book!

Don’t be late to the picnic because you didn’t know how to work on your vehicle!


Automotive Trouble Shooting For WW2 Vehicles, Volume 1  by The Ordnance School Spring is here! It’s time to dust off the old vehicles and get them in running order.

Automotive Trouble Shooting For World War Two Wheeled Vehicles, Volume 1, is a useful manual for anyone. Do you know what to do when the cranking motor will not crank the engine? Engine fails to start? No spark? Misfiring at high speeds or under full load? Problems with your battery or battery cables? Do you know how to adjust your breaker points? Inspect the coil? Do you know how to polarize the generator? Use a jump wire to test your main light switch? Adjust your headlights? Trouble shoot your carburetor or fuel pump? All these and much more are covered. Put a copy in your truck for those little roadside emergencies!

Wet or Dry Bath Oil Filters?

Wet or Dry Bath Oil Filters?

Oil bath filters are effective at removing dust and dirt from the air used by the engine.  If the oil bath filter was really effective then why did the automotive industry give it up for most if not all applications? Was it just too messy or not green enough for today’s world?

Which version you choose  is not really all that important as both filters work very well under most situations. It’s a personal choice that has no visible impact on the jeep.   It’s a great idea and can be environmentally friendly for all you tree huggers out there.

Some of these folks that pooh pooh the dry air filter are the same ones that tell you to use silicone in the brakes. One modern idea is bad, the other isn’t? Neither one can be seen.

Don’t try doing this with an oil bath filter! Your jeep fender will get an oil bath.

Besides if I spill my dry air filter on the fender it doesn’t leave any trace. Trying doing that with a loaded cuppa oil.

I’ve been running my dry air filter for 25 years and it works great. Why did I do it? Well, because I used to drive my jeep in sub-zero weather. You can’t have oil in the oilbath filter in sub zero weather. You are supposed to drain it and run with it dry. How effective can that be? So I converted and haven’t looked back.

The dry filter cartridge easily goes into the canister with the steel adapter.

The adapter I use was made/sold by USM back in the early 1980s.  It’s long out of production.  A friend of mine made a limited production run of adapters made from plastic.  These proved too expensive to sell for a reasonable price.  But have no fear some clever folks have figured out how to make an adapter for parts of your toilet!  Yes, the doughnut ring can be used for something else besides a toilet.  The added benefit is that these rings are pretty cheap compared to the steel or plastic adapters.

People have spotted a lot of issues on my jeep over the years but not one spotted the dry air filter!  Don’t tell the jeep police!


Could it be the carb? Could be...

Could it be the carb? Could be but…

Failure of the engine to operate is rarely caused by carburetor defects. If it is determined that the carburetor is responsible (that is, the ignition system is working properly and fuel is reaching the carburetor), the carburetor may be clogged or the float level may be improper.

I knew it wasn’t likely the carb that was acting up!

The only adjustments the second and third echelons can make on the carburetor are adjustments of the idling speed, the idling mixture, the choke control mechanism, and the accelerator pump seasonal adjustment. Improper adjustment should not prevent engine operation, but proper adjustment is necessary for maximum operating efficiency.


Look for leaks at the fuel-line connections. If any leakage cannot be stopped by drawing up the union nut, there maybe a split tube or a poor seat in the union. A damaged flare should be cut off and a new flare made with a flaring tool. Packing with a string may serve as a temporary repair. If the fuel contains a dye, a fuel leak may be indicated by an accumulation of the dye. But it should be remembered that he porous metal used for some castings sometimes permits a small amount of seepage, and an accumulation of dye may be due to this rather than a fuel leak. Leakage may be caused by a split adapter, in which case temporary repair can be made by soldering (Editor’s Note: Use caution when attempting to solder anything used in the fuel system. The parts should be cleaned of all fuel residue before attempting to solder. If you do not already know how to solder, just procure new parts!)

Fuel Bowl

Fuel seeping out around the fuel-bowl cover indicates a loose cover, a damaged gasket or casting, or a defective float valve. Slight seepage is probably due to a loose cover. Extensive seepage is likely to be caused by a defective float valve. (Editor’s Note: The “defective float valve” could simply be the result of contaminated fuel – dirt/rust, etc.)

  1. Remove the fuel-bowl cover to examine the float. If the float contains fuel, causing it to lose buoyancy, determine where the fuel entered the float and drill a small hole (1/8 in.) at this point. Drain the fuel from the float, and patch the hole with a light drop of solder. (Editor’s Note: See comment above about soldering. Today it practical just to obtain a new float in a carb rebuild kit.)
  2. If the float needle valve and seat show indications of wear, replace them with new parts and new gaskets. From the specifications of the carburetor, adjust the carburetor, determine the correct float level, and set the float by bending the float support arm. Hold the float in the closed position and blow into the fuel-line adapter. No air should pass through the valve. (Editor’s Note: For MB/GPWs set the float with a gage or 3/8 in.)
  3. Examine the gasket. Replace it if there are any breaks or hardened sections. Be sure the new gasket does not obstruct any apertures in the housings. Draw down the cover screws evenly.

Plug Caps

Inspect all caps covering the check valves and jets. Tighten any of these that leak. Tighten the flange nuts or cap screws holding the carburetor to the manifold assembly.

Fuel Strainer

Remove fuel strainer from the carburetor or the cover from the strainer. Wash the strainer with cleaning fluid and a brush and dry it with compressed air. Examine strainer gasket, and replace if compressed or damaged.

Solex – If Your Tired of Fooling Around With Old Carter Carbs

Now if you get fed up with your old Carter, you might consider purchasing a brand new Solex Carburetor. The Solex is a good carb to use but it doesn’t work the same as a Carter when it comes to cold starting and choke.  In fact, the Solex doesn’t have a choke…it has a starter.

I just love to read a good book.

Of course, I love my jeep but the Bantam was first.
