luckily about 5 minutes from home my trailer running lights AND the lights on my dump truck body stopped working. i assume they hooked the lights to my dump body to the trailer lights. i was towing an old trailer that has electrical issues so I'm sure that caused it. Under the hood there is a 30 amp fuse #26 that i think is the culprit. (All the other similar fuses are shiny and that one is kinda black). I've never bought fuses like this before, what type is it? it's a big square one. Are they available at auto zone? Does the whole thing pull out and do you need a special tool for it?
View 3 RepliesI've been looking for the fuse that runs the trailer running lights and couldnt find it and it got dark on me.. Does anyone know if its under the hood or inside the cab? I blew the running lights fuse hooking up the trailer while the lights was on...
View 13 RepliesBeen having a on/off problem with my trailer lights. Some times the right hand side does not work, them it starts working. I thought it was my trailer until I rented a bobcat this weekend. They couldn't get the right side lights to work.
I stopped by my Ford dealer and a service tech came out and checked out my pigtail. All checked ok. It seems odd that both trailers would not work on the right side. Two different types of trailers. One is my RV, the other was a flat bed for hauling the bobcat.
My trailer wiring is not working, at least from what I can tell. Embarrassingly, I know this because the little brake light I have in my trailer hitch no longer lights up. I've tried different bulbs and a different unit, so it's definitely the wiring. I do not have access to a trailer right now, so unfortunately that's all I have to go on. It's plugged into the 4 pin jack. Is this something I should be going to the dealer for, or more like a blown/loose fuse or something?
View 13 RepliesBorrowed a buddys trailer that had wiring issues. I ended up blowing a mini fues & maxi fuse in my truck. 06 F350 CC ... Replaced both fuses in the truck and had park lights on the truck but now dont get any lights on any trailers. All factory plugs 7pin & 4 pin. I get turn signals and brake lights on the trailers but that is all. If the fuses are good were should I start looking for problems? or is there more fuses I may be missing. I have metered all the fuses under the dash aswell as under hood all check out. Where to go next ???
View 14 RepliesHooked up to a bumper hitch trailer tonight with my 13 F350 and didn't have any lights but the brakes worked. Tested the bumper hitch trailer connector and there was no power on any terminals, with the tester still connected to the same ground I checked the trailer connection in my bed for my gooseneck trailers and everything was working. Just to check the trailer I hooked up my wife's 2015 F150 and all the lights worked. Can't figure out why my gooseneck connection works but not my bumper connector, also looks like my license plate lights are not working either.
View 14 RepliesAnd new 2015 king ranch hooked my trailer up for the first time today... all lights work and brake controller reads gain output but brakes on the trailer do not work at all.
They work fine on my other truck?
Last night I was heading home from a two day race and found that my turn signals wasn't working. the running lights are working and obviously i could feel the brakes working.
well i hooked up some jumpers to a 12v battery and the 7 pin and the lights work. to make 100% sure it works i hooked it up to my neighbors Tacoma. it all worked. well..........
On my last f150 when it was new this happened to me too. it ended up being the turn signal fuse on my truck.
I hooked right back to my truck again and just made sure my plug was all the way in and still nothing so i know its my truck side.
Now my last f150 owners manual had a section to where it told you what fuse is what and where. well i don't even see the f250 fuse box is and don't know which one it is to see if its blown.
I have a 2012 ford 150 what fuse controlls the trailer lights.
View 2 RepliesI installed a new trailer wiring harness onto the back of my 2002 F250 Super Duty with 7.3 diesel engine. Unfortunately, I was 180 degrees off on my wiring. When I hooked up to the camper I blew Fuse #115 (Trailer Tow Battery Charge) as it connected directly to the camper ground wire. I replaced the 20amp fuse and all other fuses were good. Currently, I have all the truck wires to the harness isolated and have power to all of them except for the parking lights. All the lights on the truck work fine.
My truck has a interior fuse panel on the driver's side as well as two small black boxes under the hood, near the brake booster. The under-hood boxes had only relays in them. Two relays in one black box, three in the other. The box with three relays had trailer left turn and right turn relays. which worked fine. The third in that box, apparently, is for the A/C clutch, controlled by fuse #10. The other black box (with two relays), apparently, are for 4WD Shift on the fly, controlled by fuse #111. So, no relay for the parking lights.
Next, I pulled the fuse panel out a little and checked continuity from the end of the parking light wire (brown with white stripe) at the back of the truck to the back of the fuse box and found that it was a good wire with no breaks or shorts to ground, however no voltage is showing at the parking light wire when I turn on the parking lights. The harness at the back of the fuse box has several wires going into it. The parking light wire (brown with white stripe) is in the same harness as the back-up light wire (black with green stripe) and the back-up light does have voltage, when I put it in reverse.
I'm not sure what happens inside of the fuse box, i.e., how does one fuse run a few wires... is there some kind of circuit board? I know the easy way would be to run a vampire connector from the truck parking lights, or maybe the license plate light to power the trailer lights, however, I'm just not built that way.
A little background information is that I was towing a large gooseneck trailer about a year ago when half way to the destination the lights quit. Not just the trailer but the truck tail lights, turn signals and everything except the headlights. Well after getting there and unplugging everything it stayed the same. Well on the way home without the trailer the lights began working again. All the truck lights acted as it never happened. No blown fuses or anything.
Well things are are going ok since then but I can never get running lights to any of my 3 trailers to work. Turns and brake lights are fine. What gives? All the fuses are fine and the truck running lights work just fine. One thing I have noticed is that on my horse trailer I have the little led lights on the sides operational... I would have assumed these to be the same as the tail running lights.
On 2010 150 had running lights for approx 1 year on both 4 wire and 7 wire then none. Nothing changed, Checked fuses, all ok. Checked on back side of plug, nothing. Everything else works.
View 14 RepliesI added LED lights to illuminate the running boards on my Lariat. Did this about 15 months ago and all was fine until this week and I noticed they weren't coming on any longer. Both sides are out of commission. The running board lights on each side are wired to the respective plug for the running board lights on each side. The interior lights that are on the same circuit work fine (fuse #12 in the passenger side fuse box).
So I'm scratching my head trying to figure out why both sides have gone out at the same time but the fuse is ok. It's winter here and my truck doesn't completely in the garage so I'm hoping to limit my time lying under the truck out in the cold, on a wet floor! I thought there might be another fuse in the engine compartment fuse box but there isn't, at least according to the manual.
Just bought an 04 Super duty with the factory plug 7pin and 4 pin plug. Checked the fuses and finally tracked down the 2 relays under the hood but can't seem to find anything wrong. Everything on the trailer works except for the running lights. Is there another fuse or something I have missed? Trailer works fine on my buddies Duramax and worked fine on my old 97.
View 14 Replies03 f350 7.3L. Have no power for the trailer running lights at the connector end. No power when the end is split and no power at the next connector above the spare tire. I have power at the fuse (38) and the fuse is good. What is the best connection to check next? Is there a common culprit that might cause this problem somewhere? I know 3 more connectors are in the frame by the fuel tank but pretty much lose track of which one might have the wire for the trailer.
View 3 RepliesI can't seem to get my fog lights to work. i checked am both bulbs are good. I did pull out the headlight switch. I checked fuse 43 an its good. I popped dash out an checked wires to headlight switch an found the wire for the fog lights, yellow wire on my 05.
Its getting power when I pull the headlight switch out to turn on fog lights. Pulled plugs of of fog lights an getting no power to them.
They use to work. i put in some HID headlights an they still worked. then i put some led's in my instrument cluster an sometimes they would work an sometimes not. now they wont come on at all.
Looking for the right direction to disable or find out how to disable my factory daytime running lights on my 2015 F350 ? i have installed a set of Recon projectors with Haols & LEDs & want to have just the Halos & LEDs as my daytime running lights & have the factory(now the projectors) disabled so that once i turn the switch on the dash to "on" or "auto" my headlights will turn on(the projectors) and the "Halos" & "LEDs" will turn off......
View 7 RepliesI just pulled the cab and did headgaskets, studs. I put everything back together and when I turn the key, nothing, no lights, zero.
I've checked all connections and batteries are good, checked all fuses, where to start with this?
So my tail lights and license plate lights are not working. The head lights work also my gauge cluster lights are not working. Which fuse I should check. Or what it might be?
View 6 Replies2011 f350 king ranch... I have DRL, turn signals and tail lights. I have checked all fuses ( don't know if there's a relay) under hood and in cab. Still do not have any headlights, high or low beam nor do I have any fog Lights.
