Restoration of a M38A1-CDN3 106mm recoilless rifle Jeep

[Jes Andersen]

Martin, Very nice project. If its still 24 volt, you will need 2 - 12 volt batteries connected in series. That is Positive (+) to Negative (-) between the two batteries. The cables from the jeep are attached to the other posts, each on a separate battery. Hope that is clear enough or someone else will explain better. I would consider doing some maintenance before attempting to start a long time sleeping engine. Oil change at the least and maybe remove plugs and spin engine without compression to build oil pressure and lube the bearings.

Finally, another beginner's question.

Which screws should I take to place the jerrycan bracket and the footman loops? Are they screws and nuts? Any washers?

Thanks for your patience in teaching me…

The jerry can bracket is held on with 4 "screw, hex head" (we call them bolts in English) size 3/8 NC x 3/4" long, 4 plain washers and 4 lock nuts.

Unless someone else comes up with the screw size for the footman loops, you will have to wait until tomorrow for the answer. My Jeep parts manual is at work. Off the top of my head they are flat head, phillips drive (size no10 I think), with matching "keps" nuts, or in army speak: "nut, assembled, washer".

Screws are #10-24 of suitable length (1/2" long should work). Nuts can be either the type with assembled washer or simply nuts with a lockwasher.

Thank you Rob! Always a pleasure to have you guiding me!

Batteries are plugged in. Dash board is working with temperature, battery power and pressure. The horn is working too. My switch light appears to be dead. Are there anyway that we can bypass the switch in order to see which lights are good or not?!

Not without a wiring diagram, and even then it's going to be confusing. As well you won't have any circuit protection in the event there is a short to ground. Just order a switch from any of the retailers (or ebay) and then you'll know. Or if you are in a big hurry, ask a vehicle tech (or the maintenance officer) if you can borrow a switch for a day to find out.
