Upfitter #2 BD S8 30 Fuse Blowing

[OEMPlus Raptor]

Hey guys, I've taken my truck out a couple times and this past weekend it happened again. I have my BD S8 behind the grill light bar wired to switch number 2 (15a) and I keep blowing the fuse. I'm going to check ground, but the weather pack connector is tight and not sure what else could be causing it? It's happened twice while off-roading and having it on.

Thanks, any input would be appreciated.

I'd check the entire cable length to see if it is shorting out somewhere... maybe it's rubbing somewhere?

need to use a relay

Thanks, I'll look it up. Never installed one.

need to use a relay

So a relay is needed for a 12a draw on a 15a circuit?

y would a relay change the amp draw . a relay is just used when u r trying to isolate voltages . and as a switch

I wonder if they draw more amps on startup ? usually the biggest amp draw on anything is the startup

The inline fuse in the wiring harness or the up fitter fuse?

You’ve gotten some good suggestions already, but before throwing a relay at it, I’d test to see if there’s a short. If you wire pos. directly to the battery, does the inline fuse pop?

What do the wires look like- inspect from the light to the connection points.
How are the connections?

If everything checks out, you have good crimps, no severe bends in the wiring, etc. a relay is probably a good idea. Maybe not technically “required” but probably better overall.
