He is being paranoid. You can do what he did, but it isn't necessary. If you rub a wire through it is going to short to ground and blow a fuse no matter what size it is.I am going to try and wire my light bar tomorrow but I ran across this video.
At the 6 min mark he talks about getting smaller fuses to protect the lights. What is the purpose of doing that?
I just tested the light by jumpering it straight to the positive side of the battery rather than through the upfitter aux switch, and the light started working. The only concerning part is that when I first touched the wire to the battery terminal, it sparked/arced and got hot enough that it slightly adhered to the terminal. After that initial connection, it wasn't arcing anymore, and no other issues. I then connected the positive wire back through the aux 1 terminal in the upfitter switch, and it works through the switch now without blowing the 40A fuse.I just installed the Baja Designs Onx6+ light bar kit (448031) the way shown in the video from Eddie's Garage and it is continuing to blow 40amp fuses in Aux 1 on my 2022 Ram 2500 upfitter switch box. I looked over all of the wiring and couldn't locate any damage or potential shorts. I'm currently using the BD wiring harness and cut the harness just before the relay so it only has the black (-) and white (+) wires. I'm using the standard connection without the adapter so coming from the light to the connector it has the Black in location A, white it location B, and a small green (control) wire in location C. On the other side of the connector heading to the upfitter switch it has a Black wire in location A, and White wire in location B, so not seeing any way it could be cross-wired/reversed polarity.
Anyone have any ideas of what could be going wrong here and what I should be doing to troubleshoot any potential issues?
Here is a quick couple pics from tonight to show the spread of it. I think mine are pointed a little low. Can send you a video if you want (message me your email).How is the brightness on this? I am looking at adding to supplement the crappy halogen lights on the tradesman. Also thinking about a 30" diode dynamics. Looking for experience with either about how they help.
