88 Ford F350 Dully 460 CI Auto Transmission. My sister uses this truck to pull her lead sled 30 ft Gooseneck 4 horse trailer with living quarters. Everything has been working great until the other day. She was having new tires put on the truck. When the mechanic started the truck to pull it out of the bay, the solenoid stuck and the starter kept running. The mechanic pulled the neg battery cable and pushed it out of the bay.
Sisters friend replaced solenoid but starter just spined.(bendix gear) She called me and I replaced the starter and the truck starts and runs fine now. However it doesn't have rear stop lights, rear hazard lights or back up lights. The front hazard lights work fine. I have brake lights running lights on the back of the truck. I checked the ground from rear light socket with ohm meter and it is good. Ground check of back up lamps also show good ground. Power to rear tail lights, no power to brake lamp or back up lamp. I have checked fuses, stop light switch seams OK. Any Ideals.

 

I must not understand first you state you dont have brake lights then the next sentence you have brake lights....but if you dont have power on the wire then back probe the wire until you find the break or you could try checking the switch at the brake pedal, it could have been kicked by big feet or just went bad...it's a place to start.

 

sorry, Thanks for catching the mistake, Have rear tail lights, No brake or back up lamps or rear hazard lamps.(front hazard lamps flash) Already replaced the stop light switch. Wonder if the wires to the starter solenoid were put back on correctly. All the aux wires are attached to the Pos term on the solenoid with none connected to the neg term. Solenoid works fine. # 2 wire from battery connected to one post on solenoid and #2 wire from other solenoid post
goes to the starter

 

all wires for the solenoid go to the battery side, except for the one going to the starter, and the small push on trigger wire.

 

OK that's what I thought. One wasn't connected to the battery side so I changed it. Still no luck. Another thing I found while trying to diagnose the problem. No key in ignition, hazard lights on, front working, rear not working. If I turn left turn signal on (still no keys in ignition) the left turn signal bulb blinks. Turn the right turn signal on and the right turn signal bulb blinks. I am now thinking it's the turn signal switch in the steering column. Going to go out and rent a steering wheel puller to mess around in there. Really do appreciate your help Jim

 

forgot to say it is the rear turn signal bulb that blinks when I turn the left or right turn signal lever .. still with no key in ignition...

 

Like i said, you'll probably have to back probe until you find power.
2 years ago i got put into a ditch. Lost my brake lights and signals on rear. Crawled under truck to find i had ripped the front wiring harness for my plow lights apart. Just saying it could be anything.

 

"Just saying it could be anything" is an understatement. LOL.. I've been crawling all over under the truck tracing wiring. Have removed spare tire to get a good look there as well. Pulled, pushed, probed all around so far no luck...Apparently I haven't probed the right thing yet UGH.... Will let you know how the turn signal switch probing turns out. If I can't find it soon I think I'll just hot wire back to stop lights and put a switch in to activate stop lights manually..
;-)

 

it sounds you may be on the rite track with the turn signal switch. it is very possible wires got crossed and burned out the switch.
brake light power comes into the brake light switch, and out into the turn signal switch. so if the turn signal switch is fubar on the rear circuit you will loose both the turn signals and the brake lights.

 

Update. Got into steering column today but was interrupted by rain. Sister has no garage so doing it under the shade tree...(true shade tree mechanic here) Will continue Sunday.
