Gary Lewis Posted February 8, 2022 Share Posted February 8, 2022 All right I've been back to work on ol' Mossberg. I have it running and driving, but I have three big problems: 1. The throttle doesn't seem to go all the way back to idle. If push it back into place at the throttle body (by hand) it'll go back. I've cleaned the springs and the assembly at the top but maybe its because of the cable itself? 2. I have no hazards. Is there only one flasher for the 86 Bronco? I'm only finding one on the fuse panel (nothing behind it or anywhere else). Really don't want to replace the directional switch in the steering column... 3. I have no tail lights, brake lights, or reverse lights. I'll eventually figure this one out shooting wires I guess. I'm just complaining to complain... Hope everyone is doing well! I would pull the throttle cable off and see if that makes a difference. And maybe lube things with a graphite or Teflon spray. As for the hazards, there is supposed to be a second flasher on the front side of the fuse block. That's the hazards flasher, and if it isn't there you won't have hazards. On the rear lights, that sounds like a ground problem. All of the rear lights on an '86 ground via a wire that comes into the cab and goes under a screw on the firewall ahead of the radio. Check that ground. And/or provide a ground to the tail light setup temporarily to see if that fixes it. Link to comment Share on other sites More sharing options...

There is one on the front of the fuse panel, but not even a place for a second one on the back. I can't find a place for a second one on an 86 Bronco anywhere? The Haynes manual talks about one "one the right side of the instrument cluster" but am not seeing that either... 2. The ground by the radio on the firewall...is that visible with the radio out, or do I have to take the rest of the dash out to access it? Thanks for your help as always...

I'll take a picture in a bit of the back side of a fuse panel to show you what I'm talking about. But you do have the pull the screw(s) to get to it. As for the ground, you should be able to see it w/o pulling the radio. But you can test by pulling one of the tail light assemblies out and grounding a bulb to see if that works.

That is a super cool resurrection project. seeing your wiring harness running across the rear floorboard helped me out bit, by the way. Did you get straightened out on your tailgate motor?

Here's a shot of the rear of an '82 fuse box on the left and of the side on the right: Link to comment Share on other sites More sharing options...
gatof16 Posted February 8, 2022 Author Share Posted February 8, 2022 Here's a shot of the rear of an '82 fuse box on the left and of the side on the right: Ah those pics are perfect! It's definitely missing that back flasher. Since it doesn't look "indented" like the front, I thought there wasn't a spot for it. @StraightSix As for the interior, it's still a work in progress. I got the dash and the kick panels painted, and I'll install as soon as I get my wiring issues done. I got the front seats upholstered and temporarily installed the driver so I can test drive around the neighborhood. Still haven't tackled the rear window yet... Also, I filed for a lost title last March and FINALLY got it in! I'll get to work this weekend and give you an update... Link to comment Share on other sites More sharing options...

Ive been inside the tailgates of these a few times, its not as bad as youre probably thinking. There is a 2 wire plug near the bottom of the center support of the tailgate, those are the wires for the motor. Its fairly easy to jump power through that plug to get the window up or down in a pinch. Removing the 4 bolts at the bottom of the window pane will allow you to remove the glass if need be. If you have to remove the window motor, be careful. The spring that assists the motor in raising the glass can cause the arms to slam shut, potentially causing serious injury. At some point ford added a bend in the bracket to prevent this (arms hit the bracket). Im not sure if our trucks have that. If you take the window motor out, perhaps consider replacing the plastic balls in the coupling with steel ones. I have a few laying around. The plastic balls (not pictured) go between the two parts of the coupling. The plastic ones eventually disintegrate causing the motor to spin but the window to remain in place. Ive had good luck opening the tailgate then rolling the window out and supporting its weight on a chair, pile of boxes, etc. It seems to make working on the tailgate much easier.

Thanks for the advice! Ill probably tackle this last in case I have to leave the window down and then of course it will snowpocolypse in Oklahoma. I found an old flasher and plugged it into the back of the fuse panel and the hazards worked! Seemed really slow though... Link to comment Share on other sites More sharing options...

Seemed really slow though... are there any bulbs out or switched to led? low amp draw will slow down a flasher or even stop one if all bulbs are led. there is an electronic one for use with led. then again it could just be an old weak flasher Link to comment Share on other sites More sharing options...

One small step for mankind. Link to comment Share on other sites More sharing options...
