Trying to get my 68 Charger wired up and running

I took the cluster out, did the white face gauge thing and while it was out took the opportunity to change all the bulbs (everything was pretty much burned out so I started fresh)

The wiring forward light harness was shot, so I bought a used/working one (Im already thinking that the issue) purchased two new marker lights plugged in all in and here are the issues I have now

The black wire that goes on the alt gauge gets hot hot hot hot..man like really hot just with the key switch on (I checked the grounds and the cluster is also grounded)

all the lights turnsignals work with the exception of the driver side turnsigal is dim when it blinks when and the parking light (same fixture) simply wont turn on everything on the passenger side is working

ok..where do I start?

Beer!

Not sure what to tell you, but you need to figure out what is runnin throught the black wire. Does the whole wire get hot. or just a connection? We need a wireing diagram to get to the bottom of this.

Recheck the assembly of that ammeter gauge, make sure the insulators are in the correct order. Thinking maybe it's grounding.

I am thinking that as well Andy, they are correct. That black wire getting heat must be because of a faulty ground.

I am in a 10 yard fight with this electrical, because the car has has a lot of things taken out of the car (the harness hasn't been cut thankfully) but the radio, ac, rear defroster ashtray etc are all missing so I have orphaned wires and conenctors everywhere

It's hard for a faulty ground to cause an overheating condition. You have something drawing too much through the black wire, or the wire has some sort of resistance causing the overheat. Do you have an amp meter you can connect in line?

Wow even with my eyes, I can follow the black wire...

Piper

i think I am in for a doozy

the green wire goes out to the super coil....going to find out where these black go

Piper
05-05-2013, 01:53 PM
The red goes directly to the cluster, the thick black one goes to the alt, and the black with the tracer out to the ECM...I am a thinking it needs to all come out and be redone


wont be done for Carlisle at this rate..oh well!

Kevin,

This style wiring diagram might come in handy, as you can take it outside while you're working on the car. It's cool because all of the wires are shown in the correct factory colors, plus it's covered in laminated plastic, so you won't have to worry about getting it dirty, or wet. By the way, these are also offered for most all popular Dodge, Plymouth and Chrysler models, as well as other makes.

I am thinking, buying new dash, engine and forward light harnesses.

question for anyone who replaced the dash harness, does the whole dash need to come out? or can it be replaced while the dash is in place

these look promising

I've changed all the harnesses in a 67 Charger (or Discharger as we called it) with out taking out the dash. Course I was 25, 145 lbs, and flexible. None of the previous descriptions I am anymore.

You don't need to take whole dash out.

Kevin,

You do not have to remove the entire dashboard assembly out of your Charger to install a new dash harness, but you will most likely need to remove some of the various parts such as the gauge cluster, glove box liner and a/c duct work if your car has factory a/c to give you access to the backside of the dash and firewall where the main dash wiring harness is located.

As far as removing the entire dashboard assembly from the car goes, the biggest drawback of doing that on a Mopar. is that you will have to first remove all of the internal and external windshield moulding trim, the windshield glass and the windshield gasket in order to access the fasteners that attach the metal dash shell to the body, so unless you want to go that route, you will have to work inside of the car and remove dash parts as needed.

Regarding the M&H wiring harnesses sold through Year One. I went that route during the restoration of my sons 72 Dart Swinger back in 2005-2006 and I was very happy with the workmanship and overall quality of the various harnesses that I purchased. While I did not purchase one of the M&H main dash harnesses due to the hefty price, I did purchase a forward engine and front lighting harness, as well as the dash to rear tail light harness. I also purchased one of the M&H engine and front lighting harnesses for my 66 Coronet many years ago from Year One, but have not installed it yet, but once again, I was very happy with it's quality.

Just be aware though, that buying a main dash wiring harness does not mean that you will receive all, or any of the additional smaller wiring harnesses used for various options such as a/c and other similar factory options that plug into the main harness, so verify carefully with Year One, or M&H if you deal directly with them, exactly what you will receive with the main harness you purchase for your Charger. ;)

thanks for the responses (and encouragement) gents, the bulhead looks like it comes in the replacement and those wires that rewired to go straight through(in my picture early...well I don't know if I like that


Rich I am with ya..I took out the drivers seat the other day, because I was wedged between seat and the dash with the seat in..and the first first time in my life I had a flash thought "I cant get up...I am really stuck"

Yes, that has happened to me too, but my whole arm was way up inside the dash of a modern car. Also it seems that the dash frame keeps getting closer to the floor as time goes on. I can't seem to get my eyes far enough away to see.

On a more serious note, do consider taking the windshield out if it's a contender for replacement. It woud be a shame to fight that much with the harnesses only to replace the windshield in a year or two. Then you can get into everything easily to fix, not just the harnesses.

windshield has to come out anyway because its has what looks like it was hit with a BB was saving it for when its time to do the roof skin..I was laughing at myself when I put the new wipers on the car

Kevin,

I just turned 58 yesterday, which is 406 in dog years which is about how old I feel most days, so I feel your pain my friend! ;)

I'm facing the same type of decision on my 66 Coronet 500 as I start it's interior restoration. My car still has it's original factory installed windshield glass and windshield gasket in place which doesn't leak or have any other issues, so I'm really hesitant to remove those pieces to allow me to remove my complete dashboard assembly for restoration outside of the car. I'm also hesitant to remove the windshield due to the all of the horror stories that I've heard from others who have dealt with leaking and fitment issues after they installed one of the aftermarket windshield gaskets, but the thought of having to completely restore my dash assembly inside of the car makes my neck, shoulders and back hurt just thinking about that project! :p At this point I'm still not sure which way I will go with that.

I'm not sure about you Kevin, but I'm starting to fell that I'm getting to old for this classic car restoration stuff! rofl

Happy Belated Birthday my friend!

This car is driving me mad! My son doesn't know I have it yet and thought it would be cool to drive it up to Carlisle when he comes to visit, it runs and drives so its a mater of just making it safe to go down the road (sure it will have faded paint...but I am ok with that for now!)

but as I get into it...its like flipping over a piece of wood or rock in the yard....how many bugs can fit into a such small place ? Every time I peel something back or unplug stuff I am uncovering all sorts of scary stuff thats hidden

Thank you Kevin! :)

As far as our old cars go, when you consider that Chrysler basically designed these cars to last 5 years, or 50K miles to satisfy the companies warranties at that time and you consider the technology and some of the materials that were used, it's truly amazing that there are as many of these cars still around as there are. This is mostly due to folks like we have here on the DCR who love them so much and REFUSE to let them die off and become nothing more than a memory. As both the owners and the cars themselves get older, who knows how long this fight will continue, but for now, lets keep trying to find ways to keep your cool Charger and Coronet and my old yellow beast alive and well and on the road scaring the crap out of all other non Mopar makes and models my friend! :D

First thing to cvheck is the bulk head connector. Second things is check for a parasitic draw. Third check grounds under dash. Amp Meter is notorius time bomb.

A good choice Kevin, but just make sure that you get ALL of the wiring harnesses you need to do the complete car, especially regarding the dash harness, as there are several sub wiring harnesses that plug into the main harness and those smaller sub harnesses are almost never included with the main harness. You can also order a custom engine harness that will allow you to run an aftermarket electronic ignition set-up, so there are several things to figure out before you place the order. ;)

I did a extensive re-wire on my 67 this past winter. I made my own harness. Being my car is not a 100 point show car!
I wanted the safety and security of modern voltage regulator, altenator, and ignition.
Without a schematic it's hard to figure out what's what!
I found working on one circuit at a time. Test. And move to the next.
