It is the hazard circuit, not blinkers.
How did you determine that again? I'm not sure I read anywhere in the posts, so just checking for my own information.
I checked the functionality of the hazards on the column and they worked fine.
This might indicate then that the fault is not in the hazards either. But no guarantee just yet.
I then disconnected all grounds to the light that is flashing and it still flashed.
That sounds to me like it indicates another problem. If you disconnect the ground then that light should go out. Period.
So this tells me that it's hunting (and finding) a supplementary ground somewhere. This is the right front, correct?
Is this a new light housing? They're well known for being wired backwards, but it sounds as if yours might also be cross-wired somehow and getting a ground elsewhere. Although I suppose if you left it bolted to the grille, it's grounding through the housing. Not sure if this is a good thing or not, but it sounds like right now it's not.
Next I unhooked the steering column connection and it still flashed, so it isnt in the steering column (which is also new, flaming river).
Definitely rules that out. Good to know.
So power is getting to the light circuit through a short with something else.
just wondering if it could be the flasher relay? might be worth a try. to be continued
No. If it was, then they'd all be flashing all the time. Not just one, because the one single flasher relay feeds all four corners (through the steering column as a matter of fact) so if all of your 4-way functions work when you flip the switch, the relay is fine.
However, a short is a short and are often in the strangest places, so if you did not already then do what Rustytruck said and swap the two flashers to see if things change at all.
got the light to turn off tonight by unhooking the Pertronix plug in.
So now you're on to something. But now you have to review just exactly how you connected the ignition and to what circuits and may even have to undo some of them to trace the problem.
Normally there is ZERO possibility that an ignition component can effect ANY lighting component. But since this is aftermarket, you need to dig into it further to find out the common issue.
Still reading wiring schematics trying to figure out how power is getting to the light wire.
The schematics won't matter because you have a Centech harness and that has very little to nothing in common with factory wiring. So a wiring diagram for a Bronco from one of the books no longer applies.
Unless you found a schematic that someone put together for a Centech? If so, post it up!
check all your green wires with red stripe, 12 volt power wire from ignition goes to multiple connections.
No more Green w/red stripe wires unfortunately. Centech harness, so just solid colors for 99% of the wiring.
However, Green is still a common accessory wire. We just now have to find out which ones are hot in ACC as well as ON, and which ones are hot only in the ON position.
brncofinatic, is your ignition system hot in ACC? If so it should not be, because you can burn things up while you're listening to the radio or just working on the electrical system in ACC mode.
Find out if any of your ignition feeds, if any, have power with the key OFF or in ACC
I forget, does the light flash all the time? Or just when the key is in one of the active positions?
swap your 2 flashers and see if the problem follows the swap.
Did you do this yet brncofinatic? If not, even though it is unlikely to show a fault with the relay, it might just highlight something at this point!
from the battery negative do you have a ground wire to the body and engine Block. very important grounds the mounting of the starter solenoid to the body, factory voltage regulator mount to the body, the ground wires to the turn signal and the head lights to the body and out back at the driver side rear bumper at the taillight harness there is a ground to the frame. mounting screws for the taillights and on the tail light housings the rivets holding the tail light housing pieces together. there has to be a good ground for the gauge cluster.
I do have all those grounds in place except maybe the gauge cluster, I will check that one.
You've added a ground to the body from the battery? From the engine to the body? From the body to the dash possibly? Any others you added? Ford did not have many obvious ones, but they're needed. And not just the ones included in the Centech harness. Those don't count in this hunt.
There is no separate ground for the cluster unless you added it yourself. Which is a good thing to do no matter what. It normally grounds through it's mounting screws to the dash. But this is not always enough with older rigs.
And speaking of which... Is your Bronco rusty? Has it been painted? More than once? What about the dash and interior? Painted too?
I did get it to stop and is is related to the Pertronix ignition. I disconnected the wire harness from the HP box and the reconnected it and the light quit blinking.
Got a pic of your under-hood setup we can see?
