If you tell me which Ram this is, I will find a wiring diagram.
Ok, first of all before I get that wiring diagram, if you are running a jumper right from the battery and also jumping to a good ground, then it's not going to be a fuse or relay. When you are running these jumpers, did you check again with your test light?
Anyhow, here is the wiring diagram,
Where exactly did you run these 2 jumpers to at the bulb, harness, where?
Make sure you run the ground jumper all the way back to the battery negative post to rule out a bad ground.
That is why I asked "Where exactly did you run these 2 jumpers to at the bulb, harness, where?"
I don't know what scotch blocks are. Are you sure you are jumping the correct color wires cause aren't both sets of fog lights in that same wiring harness connector? So you are jumping positive to the white/yellow wire and to ground at battery from the black wire?
use the test light in case the bulb is bad.
Disconnect everything except what is going through the bulb and then use an ohmmeter to check if that circuit is complete.
