Default Electrical Woes Still

The car is a 1972 340 with MSD ECU and Optima red top battery as the only options.

!. Head light switch on
No low beams
right rear tail light out
brights work, new set of head light bought to correct this problem previousally.

2. Turn Signals Switch
Turn signals will not work
Turn signal to right will activate left tail light
Turn signal to right will allow brake lights to work
turn signal left or neutral, no left tail light, brake light or turn signals.

3. Dome light will not work when doors are opened will work from headlight switch.

4. A\C compressor works from both A\C positions and defrost position.

All of the guages work, new fuses installed, each dround checked reads approximately the same resistance. What should I do ????????????

Oh, man! Is there any evidence of somebody else trying to rewire this car in a previous life?

man George,you are going to need a book with the wire dia. and alot of patience.The only thing that I can help you on is that #4 problem is normal.
One thing to look at is the high beam switch on the floor,I had one go bad and it did weird things.

Question gremlins

First off replace dimmer switch.Second,replace turnsignal assembly.If all else fails,see your local pyrotechnition and get about 10 pounds of good rock powder and a fresh blasting cap.Works for me.

Default Mopar Electrical

Chances are, when it comes to Mopar electrical systems, The answer to the problem is gonna be strange.

I had a 73 Charger That was always over charging the Battery (ampmeter always pegged) and (the Battery would get hot.)
The problem "believe it or not" was the drivers side dome light switch (in the door jamb) was shorting/grounding to the body.

Very Strange!

I know its not the answer to your problem, but then again, maybe it is

A pinched wiring harness can cause a lot of weird electrical problems.
#1 ?????bad dimmer ????
#2 Sounds like the turn signal switch is bad.
#3 check the door switches is power getting to them?
#4 This is normal operation. Having the A/C on during defrost cools the air so it can't hold as much moisture then its heated by the heater core and blows out hot dry air that keeps the windshield from fogging up.

Get a good wiring diagram, a volt/ohm metter and, a lot of troubleshooting. The meter is good for checking the parts so you don't waste your money replacing a good part.
If all else fails make friends with an electrical maintenance technician.
