Hello -

Prob one of the weakest but equally frustrating requests for help. I recently started popping fuse 95 - Vehicle Power 2. This has happened twice in the last 2 weeks. It only happens on drives longer than 30-45mins. When this happens the Raptor will also throw a bunch of Evap, Purge Valve, and Auto-Start-Stop error codes. I believe this is due to something overloading the fuse first, it blows, then these other items are no longer able to communicate with the PCM. So basically these are symptoms, not the cause.

Here's what's been done to the Raptor

Auto-start/stop disabler installed behind the switches in the stereo head unit 5 months ago. No issues with blown fuses

New Rough Country fog lights installed about 1 month ago. Drove multiple times since installation and had no issues with blown fuses prior to 2 weeks ago
When the fuse blows these are not on nor do they stop working should you flip the Aux switches on

Had a mobile detail service come out around the time this started happening, noticed some other oddities after they were done, but just chalked it up to my OCD (kinda like when the wife gets in the truck and screws with everything, putting nothing back to how she found it)

My guess is there is a wire or something grounding out somewhere on the truck. My questions A) anyone run into this specific fuse blowing B) Is there anything that shows exactly what the Vehicle Power 2 receives from (meaning what all is connected) all I can find and assume is EVERYTHING which is a needle in a hay-stack...

Thanks in advance for any insight

If you don't have an answer in the next few hours I can look up wiring diagram. Sorry swamped at work right now and was just checking in for a couple of minutes.

Do your aftermarket lights have amber backlighting or anything that might be tied to the headlight?

Nope, and I tore everything apart this last weekend to double-check there were no loose wires or anything shorting from the front end to the firewall and under the truck back to the tank. All signs point towards an internal short coming from the evap purge valve or other related codes. So instead of spending more time ripping through everything, I've got it scheduled at a Ford dealer for them to figure it out. It's only got 31k in miles so it's covered...

I looked up the wrong year and it shows multiple sensors/solenoid on that circuit which all it would take is one to be shorted internally or the power feed wire shorted to ground intermittently to pop the fuse.

Perfect, thanks for the additional info man!
