Radio Junction Box

[tsmgguy]

The old MB has what looks to be a radio junction box neatly installed under the hip pad on the right side of the body. It's very clean; none of the blanks are knocked out and there is no associated wiring.

Does anyone have a photo or a link to a photo showing a correct, original box installation?

Would the box ever have been in place as a factory installation without any wiring whatever?

Thanks much!

Howard, I think they were installed with the box, conduit, and the wire going up to the firewall at the factory. I have a 1943 and 45 MB both of which have the radio box, conduit, and wire. Neither jeep apears to have any holes drilled to indicate a radio was ever installed.

Nabholtz states on page 86 the radio terminal box was added March 1943 at MB217543.

Here is the one from Lloyd White’s 1943 MB.



And here is the conduit available from Ron Fitzpatrick.

Thanks for the replys, and thanks, Mark, for the photos. The box on my jeep is identical to the photos, without the conduit. I wonder where on attaches the end of the wire leading to the box?

Here is another photo from the same site, this one on the SCR-510/610.



My jeep has a much different power set up, but I seem to remember the Standard MB/GPW conduit running just behind the front seat to body mounting, going into the transmission hump area (your body should have a hole there). The wire then exits out the conduit under the body and with a few wire clips is connected to the starter switch.

The above drawing has always confused me a little as it seems to have the cable go all the way to the battery for jeep before the terminal box was standard. That may be because early starter switches had shorter terminal studs.

On my 45 GPW,s old tub, (Too far gone to use it) it had the conduit thru the floor and running under the pass. seat but no junction box. The conduit had been cut off with a torch short of the box. I found no bolt holes to indcate that a box had been installed, probobly filled in.
My question is, were the boxes bolted thru the tub side wall and if so, how
many? In the pic i see one bolt, lower left corner. Would this be one of the mounting bolts> Am thinking of re-installing the conduit and box.

Also...Was a first aide box correct for a 45 GPW and if so, was it mounted on the dash panel? TIA for any help.

Don,
The box is held by 4 machine screws from the outside wall of the tub, there should be 4 x Elongated holes. The washers are lead on MB's and lead coated steel on GPW's.



The box has 4 x holes on the back side to accomodate this fitting.





As for First Aid boxes, if your jeep has the 4 x holes in the dash then it was originally fitted with a First Aid box....if no holes are present, first check behind the dash to see if they may have been welded up, if not, then the tub wasn't fitted with one.

Hi Don and Jon,
For the sake of correctness, an MB has hex head bolts here, GPW's used screws.

Thanks Jon and Al for the quick reply. Just what i needed to know.
As i mentioned in my post, the conduit had been cut off just short of the box. I'm going to try to repair it and use it since it is original. If the drawing is available, i'll order the drawing for the radio box.
Thanks again to the two of you.

That pic of the radio filter box is made from Jons' drawings. If you can get some "Electrical Knockouts" 1/2 and 3/4" from a contractor and a hole punch set they are really easy to knock up(as JR would say). Use a belt sander to shave the edges so that they stick half way into the holes from the BOTTOM side and tack weld or braze in place. Also the stand-off is off an electrical service I got due to an accident at work and modified to fit the situation. Another item the box itself is lead coated-but the lid is NOT.

Thanks Pauli for that info. I have a good friend who is an Electrician
and i know i can borrow his knockout tool. I also have a welder.
Thanks again for the tips. Now to contact Jon.

Hi Group,

Of coarse the other way to go would be to buy a NOS box from Brent Mullins. The ones he has were intercom boxes - same box as the jeep used just different guts in the box.
