CJV35/U Main light switch

[wesk]

Hello folks. Just had an interesting questions asked of me as a PM and thought the many CJV35/U owner/members here may also be interested in the question and it's answers.

The question is:

IS that switch in the dash to the left of the steering column the light switch? It looks similar to M series ignition switch. I am looking for one of those, how many positions does it have?

Since I am hardly a CJV35/U Guru I forwarded the question to Bob Westerman who was a great help.

The CJV35 light switch is unique to the V35 but looks similar to late MB light switches.

Since the V35 doesn't have any type of blackout lighting the headlight switch is wired up just like a CJ-3A light switch although it looks very different.

he also sent these photos:







I did a little bit of research on the WWII main light switches:

ORD# 506605 Switch, Light, blackout, push-pull, safety lock, assy (Main Lights) Probably the early 1st type switch.

Then came two later switches, both rotary types produced by Douglas Manufacturing (DM):

DM# 6203, WO# A11867, Ford# G8T11654 Switch, main lights, rotarytype

DM# 6244, WO#A11866, Ford# G8T11649, ORD# 7036582, NSN 2590-00-703-6582 Switch, Mian Lights, w/circuit breaker, assy. (rotary type)


Here's the 1949 ORD 9 SNL G-503 page top and the Navy CJV35 IPL page bottom.

The CJV switch pictured above also has a circuit breaker. I forgot to querry Bob on the part number in the CJV35/U parts manual.

Note, the WWII jeep used a separate 2 pos push-pull sw for the dash lights and a separate two pos push-pull sw for the BO Driving lamp on the fender.

thanks Wes!

The CJ-V35 switch looks similar in construction to the late WWII one with the notable omission of the push to turn button that those had. I have those and because of that button you cant put one of them in the V35 without drilling the dash (which I wont do).

However I have enough of those to experiment with one, losing a detent position or two and replacing the push lock with the much smaller indexing pin.

The tough part now will be the data plate that says what each position is...

But at least I have an approach to the switch!

Edit, even easier (maybe). If the M-series ignition switch fits the holes (and I bet it will), then I can use one of them. Yeah. it wont have the "park" position, but will have off and headlights. Then Im just down to finding that plate or having some made...

I started checking through switches I have.

First, here is a late war rotary light switch, the type mentioned by Wes. This one is from a Dodge. In this case a 12V Dodge. the resistor on the switch is to drop the 12V to 6V for the blackout driving light. I tried to take the picture from the same angle as Wes' picture.



Sure looks like the V35 switch is based on this one. Same circuit breaker, Some of the same terminals in the same places. The problem is that big thick push button. Other than that I could sacrifice one of these to replicate the missing one from my V35

I went through my pile of M-series switches. While most are the same two position switch with different function plates, I found an odd ball.



This little guy has only three terminals on the back, instead of four. It is a three position switch. AND, the furthest clockwise is spring loaded!

The wires on it are numbered #11 (Ignition switch feed), #14 Starter circuit and #29A (upper right tank ?). But #14 is connected to #11 in the spring loaded position. I have a feeling this switch is used in applications that do not have the facility of a foot operated starter, like the little armored vehicles with chevy and dodge V8s in them. I need to research more.

This is the solution to another problem I have. One of my M38s has a modern key start starter, so I hid a push button up under the dash for this function. Now I can use this switch instead! Bolts right in, use the stock ignition on-off plate and wire #14 to the solenoid. Works just the same except turn the switch past "on" and voila start!

If anyone else want to try this I think this is the number you would hunt down.



Wes, should this bit go in another thread so others can find it easier?

That's a HUMVEE ignition switch:

Great! Easy for anyone to find who wants to do this mod!
