67 Dart Conv. - No Tail Lights, Park Lights, Flashers
This should be pretty simple, and he already has the diagram.
Just needs help in what it shows and how it can help with diagnosing.
Headlights come on with the switch fully pulled out,
So. L1 has power and the headlight circuit is fine.
blinkers front and rear work as they should.
By this you mean turn signals. They should only work with the key position in run, or accessory.
They are not fused in '67. The flasher acts like a reseting circuit breaker.
This circuit is fine. And that's good to know because it does tie in with the hazard and stop circuits.
Courtesy lights are on but when i press the brake they get dimmer.
That would be normal with the engine off. Brake lights draw a fair amount of power.
No continous running tail/brake lights
Was this checked with the headlight switch one position out or two?
'67 Dart the parking lights (front) only turn off when the headlights are turned on.
No dash instrument lights.
They are on a branch of the same circuit that powers the parking, tail lights and maybe the dome and courtesy lights.
First the power needs to go through the fuse to the headlight switch B2 terminal, then headswitch rheostat then back to teh fuse box (tan wire) to a 2 amp fuse, then to the orange wires for the instrument panel and radio lamps.
I checked the following: Fuse box, headlight switch wiring harness, headlight switch, stop light switch (checked for continuity)
I'd double check the fuse for the parking lights, stop lights and dome. They should always be hot if the battery is connected.
If both sides are hot, then yes maybe you are looking for a break after the fuse. If not, then its break in the feed.
These are on the return from the dome and courtesy lights. In other words the switches are between the hot and the ground. Any one switch will complete the circuit.
I have power to the headlight switch via both the black tracer (L1) wire fed by the Q3 Fuse Block Feed, and from the L8 Dome Stop Tail location on the fuse block to the headlight switch.
Sounds wrong but lets look at the diagram.
Lastly, the horn is stuck on, I believe this problem to be in the steering column, but havent checked it yet. I have not checked to see if the emergency flaher switch is working properly either.
In '67 the horn relay is next to the radiator support. The horn power comes right off the altenator's Batt terminal. The power to trigger the relay goes up the steering column to the horn switch and then back down and makes its way to the relay in the engine bay.
I did put jumper wires in the headlight switch harness(at separate times), I jump from L1 (black tracer wire) to L6 Park Lights ( Yellow tracer); L1 to L7 Rear Tail lights(Black wire); L1 to E1 Instrument Panel (Tan wire), L1 to L2 Foot Dimmer Switch (Lt. Green wire) . All of these function properly when jumping within the harness.
OK.
