69 bronco turn signal and hazards inop

[D&D72]

So, back to registration.... if you have'nt done it yet. vehicles purchased in this state dont need to be inspected. vehicles coming from out of state do along with a vin# inspection. (pre 75 on the smog). thats the way it was for me 3 years ago. I dont think its changed.

Got it registered with no problems with 5 yr collector plates. The part is when I asked about the price difference doing it annually, she said that I would be required to do a tailpipe smog check. I mentioned that it was a 69 and had no emission equipment when it was made, she said it was irrelevant. I would be required to do a tailpipe test every year if I went that route over the 5 yr collector plates.

Viperwolf,

I had a minute last night to check at the flasher itself with the key in the on position ( didn't have it running though) and had no voltage at the flashers terminals. Bulbs looked good as well. I did receive the turn signal switch from wild horses a few days ago but if I don't have power at the tail lights and your saying that means "problem before the column", where would you check next before installing the new turn signal switch?

Thanks

Alex

See if you have power to either terminal at the flashers. Key must be on for power at the turn flasher. No power=problem before the column. Power=problem at flasher or column. Then look at the column wiring. Should be a 2 pin plug that goes to rear brake/turn lights and a 6 pin plug that goes to everything else. Make sure those look ok.

Thats what happned to be as well.. forgot that bit :)

OK, it's time to go more into details. There are 2 separate flashers, turn signal and hazard. They are located very close together but they have completely different power sources. The turn flasher has the light blue connector.

Turn signal flasher power comes from the 14 amp fuse #2. That fuse also powers the wiper washer pump and backup lights. Check for voltage on both ends of that fuse with the key on. It's common for the fusebox clips to rust and become unconductive. You may need to clean them up with some sandpaper.

Hazard flasher power comes from the 20 amp fuse #5. This is unswitched power so you don't need the key on to test it.

Thanks Viper, I'll check both places when I get off work today and let you know what I find

i took this picture the other day when I first started looking at the wiring. Should this have some type of flasher or fuse connected to it? I'm out of state so only have this one picture but thought I'd ask. Was just hanging by itself along with that single white with blue stripe wire. Neither connected to anything.

I haven't checked the voltages yet Viperwolf1, I've been working on th rear end, just thought I'd add this to the post to see if it was an obvious clue to no lights :)

[Viperwolf1]

The 4 wire connector is for the hazard switch on the dash.

White-blue is right turn indicator but that isn't the correct connector for it. You may have to trace that one a little more. Sometimes wire colors fade. It could be for the optional map light.

[BillsFan76]

Finally back in Colorado. That single white with blue stripe wire actually looked like a blue wire with a white stripe after cleaning it but don't see anything matching that on the wiring diagram. Picture attached. I used a circuit tester at the fuse box, I have current at fuse 1,2, and 5 from the picture I attached. Fuse 3 has no power at all to it and fuse 4 needs a new fuse.
Hopefully the pictures make more sense if I'm confusing anyone. The fuse box is actually mounted upside down for some reason.

[Viperwolf1]

The lt blue/white wire is for the cigar lighter. It was an option so you may not have it.

Fuse 3 only has power when you have the lights on and you turn the headlight switch knob to increase the brightness.

If fuse #2 is ok check power to the turn flasher (light blue connector) again.

[BillsFan76]

There is a cigar/cigarette lighter on the dash so I'll look and see if it has anything hooked up to it I'm assuming it doesnt. The number 4 fuse that had no power on either end of it at the fuse box, will the contacts go bad? Or do I probably need to get a new fuse box for that to work?
I'll check that flasher wire after work today and get back to you on what I find Viper, thanks.

[Viperwolf1]

#4 should be a constant power connection. It isn't switched on-off by anything. Same as fuse #5. In fact the power terminal of 4 and 5 should be tied together at the fusebox. You might pull the fusebox out and have a look at the back side of it. Disconnect the battery first if you do.

[BillsFan76]

I meant fuse number 3 has no power at terminal, could the contacts there be bad? 4 had a blown fuse but had power at terminal.

[BillsFan76]

Viper,

I have voltage on both sides of fuse #2. When I check at the turn flasher I have voltage at the end of the orange wire but nothing at the end of the light blue. All other fuses have voltage on both sides, 1-2-4-5, the only one that has nothing on either side is fuse 3. I'm not 100% sure where the hazard flasher is to test it, I looked all around the turn signal flasher but didn't see anything. I do have power at number five fuse though that you said was associated with the hazard flashers.

[Viperwolf1]

Ok. You should only have voltage at the orange wire in the connector. Jump the orange and blue wires together at the connector and see if you get any lights with the turn signal. They won't flash but they will be on constantly if they work. Make note of front lights, rear lights and the indicator lights in the dash and let me know what happens.

Hazard flasher is hiding close to turn signal flasher unless it has been removed. It might be flipped over the steering column.

[BillsFan76]

I jumped the orange and blue but nothing lit up inside or outside. Looks like the PO removed the bulb from one connector (unsure which of the 3 hanging is which)and the other two are hanging next to it but both bulbs look good that are intact. Also looked for anything around the turn signal flasher that might be for the hazard flasher but only see this in the picture below, is that it? It had nothing connected to it.


First image is what I thought mane the hazard flasher connector and second is the 3 connectors hanging behind the speedo that I assume 2 are for the turn signals.

What a pain in the ass

[akaFrankCastle]

Two of those bulb connectors are for your turn signal indicators, as you suspect. The third is for your high beam indicator.

[Viperwolf1]

Blue-red is cluster back light.
Green-white is left turn indicator.
White-blue is right turn indicator.
Green-black is high beam indicator.

All these lights need to be plugged into the cluster to complete the ground or they will not work.

The loose plug is for your hazard switch. Follow the white-red wire to get to the hazard flasher.

[BillsFan76]

Finally had some time to get back under the dash and find the end of the white and red hazard flasher wire. Gave the hazard flasher a pull and the entire connector and wires came out with it. Looks like the previous owner cut both wires for some reason, no idea why anyone would do that. Looking under a the dash,it's a nightmare of F'ed up wires and electrical tape. Now it looks like I'll have to remove the dash to replace that cut wire. Have a few questions before doing that:

1. Could the hazard flasher wires being cut stop brake lights and reverse lights from working? The only working lights are the headlights. Nothing else front or back.
2. Does removing the dash involve removing the steering column at all?

[Viperwolf1]

1) No, but if the flasher wires were cut I wouldn't be surprised if other were too.
2) Yes, unless you just want to pull the dash out around the column.
