No headlights, radio or electronic locks
Welcome to the forum
What about Flash to Pass, do headlights work for that?
Its a different electrical circuit
And Parking lights do work correct?
Headlights, Radio and Door Locks have no common link
The cab fuse panel(smart junction box), is the only link, i.e. all the fuses are in this fuse panel, none are in engine fuse box
But Fuse #1, 40amp, in engine fuse box does power all these fuses
Fuse #23 is light switch fuse, test for 12v at this fuse, if no 12v then fuse #1 is bad or the wire from fuse #1 to the cab fuse panel is bad
Then each head light has its own low beam fuse, #3 and #4, but power for these fuses comes from #23 when switch is on
Radio has 2 fuses, #6 and #24

Thanks. But no I have no flash to pass lights. I currently have no way of testing fuses but I was thinking it was in the wiring because it would occasionally cut off power to said things and I would mess with the wires in panel box and it would fix the problem. Now though it isn’t coming back on while messing with wires. I believe maybe a wire could have finally broke?!?
Certainly possible
The cab fuse panel is in the Smart Junction Box(SJB), which is the Body Computer, expensive to replace
Here are the wiring diagrams for 2008 Ranger SJB which would be the same in 2010 as far as I know
There are 3 main power fuses feeding the panel from the engine fuse box, #1 is the fuse that feeds the effected systems
And its wire is connect to pin 1 on the C2280A connector on the SJB
So if wiggling wires at the SJB restored power then thats where I would start, but wiggling the wires could also have shorted out Fuse #1 so I would check that before doing anything else, pull it and look at it

That connector that was unplugged is C2280A on the SJB
As shown here: http://cyoum84abk-flywheel.netdna-ss...ction-Box-.jpg
I have read of water intrusion on the SJB before, not common but known to happen
Unhook the Battery when working on electrical systems, ALWAYS!!!!
