you will need an ohms meter remove the ground / earth test as the factory manual shows' there trouble shooting in the manual for this .
touch the positive battery cable on one end with the red test lead then touch the starter positive post with the black lead is 0 resistance showing ?

Thanks Dave
Yes I build a relaykit for our Mopars. Specifically set up to address the issues that OEM wired cars have. My kit hides nicely within factory runs and requires no cutting of the OEM harness.

...years ago, I swapped in a Bosch 5 pin relay to replace the factory headlamp door relay. I was having trouble with an aftermarket headlightrelaykit. The factory relay was leaking voltage and making the doors and high beams do weird things. This led me to upgrade the relay to the cheap and...
I am having a related problem. My 70 Dodge Charger headlight doors don't work when I fip the light switch ON/OFF. But my headlights works and the headlight doors do open and close when I connect it directly to the battery. The headlight doors worked up to around a month ago. My mechanic...
...circuits - first, the low beams.
So far so good - next are the side markers.
Okay, no issues there.
Next, the high beams.
The headlightrelaykit works like it should.
Here's the dash lights.
Parking brake light works.
As does the reverse indicator.
The turn signals and 4 ways work as...
I'm not sure if this is what you are looking for but I'm installing relays in line from the switch to headlight to reduce high currents going back to the switch. Here is the kit that was suggested by another member.

...removes the single biggest electrical load from passing through the bulkhead connector.... Get ahold of Crackedback and buy his headlightrelaykit.... Your headlights will be brighter that they've ever been, they won't randomly decide to shut off at the most inopportune times and as...
On a factory stock charging system with an ammeter, should never add loads directly at the battery. Headlightrelays are a good idea, but the lamp load needs to be on the alternator side of the ammeter. If not, the loads are just shifted from the lighting circuit to the ammeter/related...
You didn't mention what year car you had. The early roundback alternators have a hard time keeping up with load at low rpm's. A headlightrelaykit from Crackedback, a member here can take care of your issue. Look him up.
Nice. I would leave it just as you have done and never look back. . F--k the Ammeter. The next improvement would be to bypass the alternators bulkhead location and get it fused to the starter relay battery terminal. Then get a headlight bypass kit with relays. With those being done your loads...
You're getting a lot of great feedback. When I watch the video and watch the clock the entire time, it looks like the clock stays stopped until the moment you turn the key back to the off position. Is that correct? There could be a situation where the starter relay and the start's solenoid lock...
...dash, below the instrument cluster. It gets inputs from the headlight switch and dimmer switch. The motor itself has internal stops that are set by the factory.
My relay didn’t work well with the headlightrelaykit I installed so I converted to a Bosch 5 pin relay.
What problem are you having ?
I would go with a headlightrelaykit. It takes a big strain off the headlight switch and provides more voltage to the headlights. I’ve done this on 2 of my Mopars.

How bright are the dash lights on you 67 GTX after doing the headlightrelaykit modification? The same or brighter? Did the modification eliminate the issue of the dash lights dimming when coming to a stop and then brighter when accelerating?
