Interesting that you mention turn signals...
The 4-ways work as they should
The left and right turn signals, work as they should...
The brake light switch works as it should and has constant power..

I noticed with the key OFF and the turn signal switch on...I get one brake light on the passenger side (not very bright)

Are the brake lights wired though the signal light switch?

The car is an original 4spd, the transmission harness is included with the positive battery cable (Hemi)
As I type this, I just realized I could check those wires where I connected them to the bulkhead Never thought of that




As Mike mentioned, these are mostly symptoms of grounding issues. The courtesy lights and brake lights require a good body ground. If the car was repainted, its very possible you don't have a sufficient ground. On my 70RR I had to scrape off some paint where the rear courtesy lamp clamp piece touches the body to get a sufficient ground for the light socket. I had to add a ground strap to the brake light housing - inconspicuously of course.

Yeah just get/make some jumpers with alligator clips on each end, take them back to the tail light housing and clip them between that and a good ground. I bet the lights brighten up right away, and once you know that's the problem you can figure out how to improve the ground situation in a more copacetic way.

Wiring problems are a heck of a lot easier to figure out using a DMM instead of a test light too, ya noob.

Concerning the yellow wire. It is possible that the bulkhead end may not have been striped and the insulation was crimped instead of the bare wire. I would carefully examine the crimp and make sure the wire is properly crimped, if the crimp is okay then it may be a defective wire.

What is a DMM?

Digital Multi Meter

Analog would work too

Alan if you have a spare T/S switch try plugging it in, you don't need to install it & an E body switch will work.....




Very simple advice that worked wonders...

I plugged in a new switch that I had in stock and everything works as it should....

HOWEVER....
I pulled the steering wheel and closely inspected the turn signal switch and could not find one thing wrong with it During the column restoration I replaced the turn signal cam with one of those parts pack pieces to retain the correct 4-way pull switch...
everything looks as it should.
How else can these things be defective?

Does anybody know where I can get a reasonable priced CORRECT 70 turn signal switch?

Using a very pointy test light I jabbed the wire and my finger more then once, right to the copper and still had no power at the bulkhead end ....I've since made a jumper wire and quickly solved that problem.

Either Year One, or your local Chrysler dealer carry the MP NORS column turnsignal harnesses,....the 70 B body is the same as the 71-4 B body, and the 71-4 E body,....i would check continuity/ and confirm wire orientation with a FSM before installing it

That I don't believe, because the switch in this car, like other 70's I've done has a narrow pull knob, where the newer ones are wider and don't fit in the slot of the steering column.

The black knob (for lack of a better term) is much wider on the newer ones

I don't know what switch you have Alan,...or where you got it,..All I can tell you is the switch that I used, was a new Chrysler repro NORS, that I purchased thru Year One, along with ALL the dash/engine and body harnesses that M&H made for a 70 440/6 manual trans Charger,....



Year One PN# FD93102 that's off my invoice for the column switch $70, it's listed as 70-4 b body and 71-4 E body

Have you unplugged the turn signal harness connector and checked the female pins making sure all of them are completely "set" in the plastic? Sometimes they back out. The same goes for the bulkhead connector.
It would really help if you had a factory service book so you know what color wire you should be checking even though Chrysler pretty much stayed with the same colors all through the years.

Having a trouble shooting kit made up always helps too. I have single wire jumpers w/clips, 4 wire jumpers w/clips, test lights and various testers..Simpson, Fluke... There are also continuity testers that look like a pencil that is run down the length of the wire.

FYI...I'm having the same problem with my '64 Savoy but at this time I have other priorities.

I hope those turn signal harnesses you pictured aren't for the same model. The wire colors aren't even close and could be a lot of work tracing a problem.

Mopar superseded the switch many times and serviced it under many PT #'s . the most recent ones require widening the slot in the column.
Current part numbers it's avail under is 4293102 and retail is about $100

I have them here if you want a current pic of what one looks like.

The 1970( and maybe 1971 ? ) switch is hard to find and expensive when you do

With the issues your describing, I have my doubts you going to see any 'problems' with an 'external' switch examination.

I tend to agree with you there Bill...no visible signs of any problem...

I have a new switch here in stock that I can "make work" but it entails modifying the column for the wider switch, which would be up to the owner.

The above two pictures were taken from EBay last night and both are listed as being correct for a 70 B Body.

The first one, the one similar to the one in the car is $275

Check with Mopar Performance and make a trip to your local dealer. Last time I checked they had the correct switches.

Why not use the trusty dremel and shave down slightly the plastic knob...
Easier shaving plastic rather than cutting metal..

The replacement switch from Mopar fits different years, we have installed many by shaving down slightly their edges..

Just my $0.02..
