Electrical Woes



Okay that's the back of my Ignition switch! The Blue wire taped on is one I put in, while broke down because coil wasn't getting fire from switch (Two Red/Golds came from that same socket from what I can make out) One hole here is empty? Any advice would be much appreciated



This were I Chased it too, I know the Pink is Labeled Ballast Resistor(Do Not Splice) I have a 12v coil and a Ignitor, Both by Pertronix! I do not need the Pink Do I? The pink isn't burnt? I can pass this with a 12v off (RUN) on switch, Directly to (+) on coil? Notice the blue wire I had to switch meeting the connector on the same side as Ballast, wires cooked out of the other side



What are these Conectors? they was behind the Lights, Wipers, Ignition to the far left just hanging



OK this is the plug I don't know about from above, the insulated block has 2 Black/Green Striped coming out (Never mind the blue look, I am holding a LED Flashlight on them) one is burnt all the way to the connector, out all the way to Dash Instruments far left/right on 69' the lights (-)? for Oil and Amps



Photo of the black/green stripe burnt slap up from the connector above! White/red was covered I removed a wire previous owner had there
(maybe what toasted the grounds?)

Any advice?

OK Going over Diagrams Posted on the site, I have the Instrument Panel pretty much squared away!

The yellow connector you are holding in one of the shots is for additional accessories. If you were to add something that needs power only while the ignition is on that is the easy place to plug it in. You can still buy the male versions of those connectors and many auto part stores.

Thanks GuitarBuilder!
I was worried these were leaving a circuit open, I am wondering if the other could have been to the oil sender?
If so I am about finished rewiring!

The Red/Yellowish stripe that's burnt on Key switch from what I am gathering, I can run Directly to the coil, From my gatherings here looking at schematics,
Oh I see a splice off it in the schematic (904) went to the bottom wire (Near Plate Ground) on voltage regulator

All this leaves is the hopefully easy Alternator Pigtail! Looks like the last of the previous owners wiring genius

[kornfed2007]

OK the Coil wire off the switch (16) Red/Gold & Red/Green, I said was to piece

1 went to the charge light

-----------------------------Pink Resistor Ballast to coil
2 went to a splitter
-----------------------------?????????????????????

I don't know what color it even was but I know it ran outside the harness sorta and burnt clean from the Ignition connector to firewall above heater behind dash then vanishes without a trace!

What are these Convectors? they was behind the Lights, Wipers, Ignition to the far left just hanging

OK I believe the black 2 prong (female) Is horn?

I recently installed pertronix ignitor and after MUCH research decided to keep the resistor wire in place... the pertronix instructions say so. If ... and that's a big "IF" ... your voltage is too low to run the ignitor you can run 12 volts directly to it to test it... it says not to leave it that way! The voltage at the coil with resistor is about 9.5 volts when running... the coil likes it and the ignitor likes it. I think running direct 12 volts (which can be 13.5 volts with engine running) is asking for trouble, both with the coil (it'll get smoking hot) and the ignitor. I think this is why the pertronix gets a bad rap... the instructions are clear as mud. They show illustrations that don't make sense.

White w/red stripe is Oil pressure.
Red with white stripe is Water temp.

I always hook the pertronix things up to the ballast wire (2 leads on coil).
Never had a problem in hundreds of early Mustangs.

Pertronix used to tell you to hook it to 12 volts, now they dont tell you that.


I had the one wire fry on my 69 van on the switch (same plug as Mustang to 69 ) .
I traced it and read the schematic and found a bad wire on the alternator, somebody scraped it years ago.
I cut a new plug from a 69 falcon harness I had and soldered it on for the switch.

I have the Ford wiring big book from 69.
But my 69 van wiring was slightly different from the book.

Are you sure you don't want to use some heatshrink instead of, or over, the electrical tape? Every time I use electrical tape on my wiring it lasts about a month before it melts away because of the engine heat and becomes a huge sticky mess.

I have had that same problem, In the past. I get the expensive tape at ACE Hardware now, LoL I also wouldn't use it under the dog house!

Behind the driver side, in the dash and instrument area doesn't get hot on my van? (Wouldn't use it in direct sunlit areas)

Probably a great Idea though on the Passenger side where the heater core and heater/returns are, I have to put a Blower Motor and Heater Coil in soon
(Grinding from fan motor - Turning the heater on fouls up the coolant)

I was definitely running it through the Pink Ballast Wire! Not spliced (which is where I expected this journey to lead when I began)
Ballast wire looked great, the 10" Red/Green stripe from the switch to the Resistor wire connector burnt? but that was a month or two, before I installed the Ignitor
I dunno????

I cut the wire out now and am going to put a ceramic style with the 2 post, (magnet/polarity)

I have the replacement "Pertronix Ignitor" already,Summit had UPS scheduled to pick it up the following day!

I am going to move to the Regulator and Alternator Wiring before installing this one, Cant see how the points have been fine for weeks, Unless the new Voltage Regulator did it? (Not a Electrician)

[kornfed2007]

Okay I believe I have found where the Ignition wire goes, (other than the coil) the Starter Relay (solenoid) on the small prong bottom right (Ignition)

Is this correct?

I am running now, Cranks great, Turns off fine,

but the schematics I can find, read 16a (Pink Ballast) 262 Brown ("I" starter relay) meet at the connector ("D" Below) that takes - red/yellow to the "+"coil?

here is the diagram (not a econoline) 67 f100 matches what I have to the wire color even! even my dash with the idiot lights (oh 68 looks like the F-series changed a little)

[kornfed2007]

Sheeeesh looking back on that nightmare, I dont remember half of what I was talking about months 6 later! Glad its done....That is all

(Aftermarket Tach, Trailer Brakes and Fuel Guage/Sender is all I have left)
