What Have You Done To Your 3rd Gen Today?

Looks great! One of the many items on my wish list...

 

Well, this has quickly gone sideways. Blows the 3A fuse immediately upon hitting the switch. One light or two. No visible shorts and wired correctly. Any ideas out there?

 

Amp Draw: 6.7A @ 12V

 

Got a matching hood decal for my bedside one...

 

Other than they're demon brackets?

 

This is when I tell you I can speak Japanese and am an air traffic controller. Then follow it up with I know nothing about wiring lights. I'm just following the directions and using the harness KC provided. Did they likely send me the wiring harness for something with a smaller draw i.e. Flex Era 3 (3.4)?


From the power source before the relay is a 25A fuse. That wire goes to the relay, then spliced out of that same wire is a 3A fuse leading directly to the switch.

 

My guess it that you have the switch wire connected to the wrong place on the relay. The switch just tells the relay to open and close. The relay handles power delivery to the lights. There should be very little draw on the switch wire.

 

Few nearby fires again. A little hard not to notice.

 

Okay, so I'll add that there is only one way to plug the harness into the relay. So if your guess is correct, then the harness is wired incorrectly from KC? I say that because it's essentially "plug and play" assuming I've plugged things into the correct places.

 

Some pics might help.

 

I just added my bed rack and smitty bilt gen 2 xl tent. Can't wait to use it this week.

 

Unfortunately, KC doesn't provide the wiring diagram online, so I don't know how the harness is prewired. All we can see from the initial post is that the the amperage in the circuit with the 3A fuse is exceeding 3A.

 

- Relay plugged in the only way it can be.
- Yellow ring terminal to battery.
- Black ring terminal to ground.
- Switched wired as instructed in the diagram.
- Only weird thing to me is how the diagram illustrates that the green wire is in the center, but then states that yellow goes to center of switch.

Yeah, I looked for one also. I've posted an image of the one that came in the box a few posts ahead.

 

Installed my new coverking seat covers this morning then took it for a drive to pick up my new work trailer.

 

Got my ball/hitch for the upcoming tow/move.



Also got my hood wrap scheduled for before we leave.

 

@calicoaran
The picture is incorrect in the diagram. The yellow wire should be in the center of the switch. That activates the relay. The writeup in the diagram is correct describing the connection order.

 

Got it, that's how I wired it (yellow center).
