electric power loss in cab

eastern · Jan 27, 2015

Was out plowing last night and dash, radio, windows, and heat died. hit a bump and comes on and off. Truck runs, lights work and dash daq shows power being generated. WTF

Sounds like a short,since these trucks are designed with quick disconnects for fast cab removal my guess is one of those connectors or a pin in one is loose.
I bet it'll be a quick fix good luck.

Try disconnecting the battery and check those connections just an idea as you may find it and fix it that way quick and easy yourself.

Did the battery but was fine for a while and this morning it did it again. My buddy is a ford tech and he told me he has seen the main wire harness that runs on the top of the front driver side spring mount rubbed through on a few trucks. I will have to check there again. Maybe it is time for a new truck. LOL

Good luck,these type of problems can be very annoying,but i bet its nothing major.

check you cab ground strap since your loosing all that at the same time.

Alright back from a nice trip to the sunshine state to a foot of snow. Now truck has lost power on cluster, radio, and heat display out but on full blower and no control over it. If I turn truck off and turn key to aux everything comes on but goes out as soon as I start truck.

thats ***ed up man.. i have had an issue with my outside air temp gauge and ford replaced it but it didnt change... also every now and then the settings on my radio for the fade,base,treble,and side to side go back to factory default and just out of the blue when i start my truck the radio turns on by itself... i know this doesnt do a dam thing to help you but its weird...

Alright so far truck ran great yesterday till this morning. Noticed on dash daq that the voltage would jump to 17v and this is when I would loose power to dash. Would this be a voltage regulator or alternator issue. I have read articles about the voltage regulator being in the cluster on older vehicles but nothing on a 2012. guess it has to go to ford.

ALTERNATOR some bitch. $1000 and a week of going crazy and all it was is an alternator. Asked three ford dealers and never herd such a thing happening but when I ordered a new alternator WHY does ford have a new part # and you only can get a reman. alternator.

Damn, how many miles on it? I have a '14 with almost 28k & am just skimming PSA (new to forum) for familiarization of my basically still new to me platform; comin from a 7.3 about a year ago. Glad ya got to the bottom of it and it wasn't more $/time. I friggen hate electrical issues.

eastern · Feb 9, 2015

2012 with 54k and had it for 3 years this month.

Platinum250Scorpion · Feb 9, 2015

Smh, hope it's better from here on out.

Platinum250Scorpion · Feb 16, 2015

You're still good, with just the alternator replacement, right?

eastern · Feb 19, 2015

so far so good. Battery light still on though. Tech has not figured out why yet. I need truck so a little black tape takes care of that till spring. LOL

Platinum250Scorpion · Feb 19, 2015

Lol, fair enough... glad to hear it's up and runnin though... always disappointed when a fella's rig is down and it's not cause he was beatin on it.

You said you were plowing when this first happened.

FYI There is a thread going on over on the TDS forum "2011 up General" on this issue. Seams Ford & GM know about this issue.

It has to do with Cold Weather, Battery Voltage dropping to 11 volts for a split second when you hit the Plow controls. It wipes out / Reset the Dash.

May want to check it out.

Try adding another ground. A bad ground can cause multiple issues like burning up an alternator, slow starts and draining batteries. Just go from the negative to the body or frame.

eastern · Mar 9, 2015

well back to drawing board. big wiring harness over frame rail behind passenger front tire went up in flames. ground wire mounted to frame at that location melted to a crisp. This is going to hurt. $1k for alternator and new batteries and now this. If I am lucky when I go back to get truck it is burnt to the ground. WTF.
