Ford Wiring/Electrical :: 1986 F150 - No Gauges / Left Turn Indicator Light On Dash Does Not Come On
Aug 8, 2013
Okay, my 1986 f150 with a 351w (non-feedback carbed) Has no lights on the cluster, and none of the gauges work (haven't tested the speedo yet, truck is not registered yet).
I also have a minor issue with the turn signals... Fronts work, no rears. The left turn indicator light on the dash does not come on but the right turn one does. All my "primary lights" (markers, tail, headlights) work fine. I have not yet tested the brake lights.
Fuses all look good, truck did have some roof leaks. I've done some research, does this sound like the dreaded voltage regulator issue for the gauges?
My assumption for the left turn indicator light is that there is a replaceable bulb in the dash (probably blown), is that right? Rear signals might be wiring (PO installed his own trailer wiring) or bulbs? haven't gotten that far into it yet...

Start out, drive about 20 minutes, get on the Interstate and the battery light comes on 2008 F 150 5.4L 4X4 - 57K miles..... get to my destination, went about 20 miles, turn around to come home, without turning the truck off because of the battery light being on and I notice the charging gauge drifting down to the left, get back on the Interstate and the wipers are slowing down and lights on the dash are dimming.....go around 15 more minutes I lose all lights on dash, wipers, defroster everything, charging gauge is now pegged all the way down to the left and the truck is starting to act up running like crap so I barely make it off the Interstate and call a flatbed, I guess I was about an hour into the trip ..... battery is only about a year old and it started fine that morning and the day before when it was about 12 degrees ...... dealership had the truck, just gave me a call and said they can't find anything ?? ..... never a days problem since I bought it new in late 07' ....

I have a 2011 Ford F150 FX4, And for a while now i have been having a issue with the gauge cluster.
while driving once in a while all of the gauge cluster turns off then back on within a couple of second. all the lights for the traction control, air bag, engine.... turn on and then turn off just like when you start the truck.
The issue only last for a couple of seconds. And it can go for a day before doing it. Brought it to the Ford dealership and they said unless the gauges are completely off there is nothing to go on by. Also once in awhile the check advancetrac comes on and will be off next time i start the truck. Same thing dealer said there was no codes and nothing then can do.
I checked all the connection at the fuse box, gauge cluster. and no issues. had the truck running and try wiggling all of the connectors, in the truck one by one with no success in duplicating the issue.
Also notice that once in awhile my signal light will flas extremely slow when having the blinker on.

OK, I just got done replacing the alternator on the wife's 05 escape 3.0 V6, after it started on fire. The 3 wire plug was melted onto the alternator, so I had to replace the pigtail. I'm 99.9% sure that I got the wires in the right place. But now, after putting it all back together, it idles sporadically, when I drive it seems almost like it's trying to start out in 2nd gear, and shifts oddly. And there are no dash lights or gauges. Headlights work fine. And everything worked normally before I took it apart.

1986 ford f150 standard cab, manual trans with 3 plus overdrive.
1989 302 rebuild v8. When trying to start occasionally the ignition continues to turn over..
Even after the engine fires, the starter continues to turn over until I have to disconnect the battery to stop it. Then it fires up fine afterwards what could the problem be.
I'm thinking the starter, or the ignition switch but I also heard it could be the starter solenoid.

I have a unique problem with my newly acquired 71 F250. The left brake does illuminate when the brake is pressed but when the right turn signal if activated the left brake light does come on. The left flasher light also does not work. All other rear ligh function are normal. I am assuming I have a short or a wiring issue just wanted to know if there was any common item that might be know about this topic. The bulbs are all new. The reverse lights do not work either but pretty for sure its unrelated.

Dash lights are not working in my 78 F150. The climate control lights come on and are dimable with the headlight switch. I pulled the cluster and the Blue/Red wire has voltage. Which might be the ground? The Seat belt light comes on at start and the left turn signal will blink. What am I missing. Oh the cluster is deteriorating. some of the bulb holes are chipping out.

2003 f150 supercrew with 166,000 on it. Daily driver. Keeps randomly blowing 10A fuse under dash that controls ABS4X4 urn signals. No routine causes. Just blows at random times. Fuses were blowing instantly upon replacing then stopped. Doesn't blow when turning switches for turn signals or when turning it to 4x4. Just does it randomly. Sometimes will go months without blowing. Tore dash apart and can't find any wiring issues there. Could be somewhere else? Is ABS4X4. Turn signals going bad?

I have a 1990 f-150 that periodically (and rapidly) blows the fuse for the turn signals. The brake/tail lights continue to work, but just the turn signals quits. Looking for a schematic of those systems?

My brake lights, turn signals, and flasher are not working in my truck. Is it a fuse and what fuse? Could it be a relay?

I have a 1999 Ford F150 6 cyl. 4.2, 2 WD with 160,000 miles. Replaced the battery May 2010.
Today battery light came on. Battery gauge did not look like it was discharging. Had battery checked they said it was a little low but OK. Then they continued test and tried to check alternator, test stopped and they said something wrong with alternator most likely.
I took alternator out and had it bench tested. They said it was OK, putting out 98 amp on 95 amp alternator. They said check wires, grounds, harness, connections. Checked connections and wires as much as possible, reinstalled alternator, light still on.
Have not checked fuses yet. Was told to start vehicle, disconnect positive battery cable and if engine continued to run alternator was good, if cut off alternator was bad and to replace. Should I try this and is it true?
What is the part on the fire wall that is between the alternator and the battery that the wire connection runs through? Can it be bench tested/checked?

My center brake light went out a month ago. Thought it was the bulb so replaced that, still didn't work. Checked the fuse and its not broken so my guess was electrical?
Hasn't come on once that I know of but I was randomly walking behind my truck and the light was on. Truck was off lights were off and key wasn't in the ignition.
Went and turned my truck on and turned the lights on and the cbl stayed on. When I switched my lights off it went out and stayed out.
Now I'm definitely thinking wiring but not sure where to start fixing?
Oh and it's a 1990 F150 XLT

I've searched all over and can't seem to find the answer. When I pull the tail light out of my 12 F150 there is a blue/wht wire and a black wire going to the back up light. I assume the blue wire is the positive and black is the ground. Is that correct?

I have an 06 F150 XLT and lately the map lights blink when starting and driving. This does not occur every time but it sure is a problem when driving at night. What is causing this and hopefully a minor repair.

I've been trying to trace down a issue with the airbag warning light flashing. The seatbelt light is flashing also. The airbag code is 53. If i search it i get the front crash sensor..I replaced it with a new sensor and pigtail. Other than that the search leads me to believe it could be anything.
I've checked and clean every connection that i could find. I haven't removed the center console yet to check the module. I did buy the truck last fall as a winter/work truck. The issue started a couple of months after i started driving it. Not sure if the module would just go bad.

2003 SCrew, 5.4, auto, 4x4.... Yesterday my left turn signal started flashing fast; checked and the front was not flashing. Picked up a new bulb, changed it, didn't fix anything.
I've tried:
-tilt wheel up/down in all settings-no change
-checked the wiring at the top of the column; still good and solid.
-swapped the bulbs left to right and vice versa-no change.
-swapped the sockets left to right and vice versa-no change.
Other info:
-the left front is the only one not flashing with hazards on.
-all original equipment, except I removed the stock side mirrors (w/signal) and installed manual trailer towing mirrors, but that was 2 or 3 years ago.
-the dash indicator light for left turn (arrow) does not come on at all.
-last trailer tow was over a month ago and all was good.
I ran out of daylight last night and at work now so I would like know which Fuse, Flasher, Relay, etc., I should check/replace and where to find them on the truck; under the hood (1st or 2nd stack of the fuse blocks); under the dash above the pedals; steering column???

Looking for a wiring diagram for a F-150 XLT LARIAT 5.8L 4BBL, all the books I have looked at show the wiring for this year with fuel injection and this truck came with a 351W with a Holley 600 4BBL, I have a few wire's in the engine compartment that melted away all the insulation, they are located close to where the harness passes the firewall before the ignition module. Is this a common problem on old models ?. Need a clear copy of the correct diagram for a f-150 1987 with carburetor, how I can get a copy so I can fix this problem before it gets worse.

Problem with my 2006 F150 5.4 4x4... Voltmeter spikes, battery light comes on, grinding noise as 4x4 engages on its own then everything returns to normal after about 60 seconds. Took to Ford who replaced the alternator and battery, still doing it so they replaced the alternator again...they checked the wiring and replaced some other misc parts and don't know what the problem is. The problem occurs once every few days, after only a few minutes or after a few hours, completely random.
