Low beam fuse issue

Hey fellow taco eaters,

I am wondering if any of you guys have issues with the 10amp fuse popping on the low beams. The same fuse for the front right low beam has blown twice now and I’m wondering if this is a common issue or just getting water in the connections! I did install the xenon Led lights which I love when they decide to work.

Thanks for the input friends

 

Nope. Double check all your connections.

 

You answered your own question. Many stories here about "I changed some stuff and now my truck won't work".

This is NOT a common issue if you don't jack with it.

G.

 

Guessing you’re using 55 watt HIds?

Edit just seen it said LEDs still might be drawing more amperage due to the cooling fans. Read the required input and output. You may have to bump up to a 15 amp fuse

 

Ya I’m confused, is he using a Xenon or LED.

Maybe he means XenonDepot LED?

 

It’s interesting though for it only to be blowing the right low beam fuse, but you are right I did order some 15amp fuses to fix it, I’m just confused as to how it lasts for a few thousand miles and then kicks the bucket.

 

Before you throw a 15 amp fuse in, I would swap sides. See if the right side still blows. Might just be the way the BCM circuit is setup or there might be an actual problem with the bulb. If the right side continues to blow after swapping I would say try a 15 amp and you should be ok. But if that blows I wouldn’t go any higher. In that case you’ll need to run a relay and boost the circuit. I wouldn’t put anymore than 15amp through the factory circuit as you might damage something. If it blows the left side after swapping I would email the company and perhaps they can send you another bulb. If it has worked that long my guess is something internal is failing in the bulb and causeing it to short or draw more than it needs.

 

If its only one bulb you are having the issue, and this has been installed for a while, and you just started seeing the issue.. could be a defective bulb? damaged wiring?

 

I would definitely second that you contact the company; they may have some specific things to check.

Yeah, because people joint the forum to mostly talk about their stock trucks. I'm sure the OP found your response super helpful.

 

I wouldnt bother with the fuse to be honest other than replacing it. LEDs draw less amps than stock bulbs so there is obviously some other issue than the fuse.

 

The LED’s shouldn’t draw much. It’s the fans that I I would think draw the most. It’s saying the only need 2.2 amps to run. Not sure if that’s the just the LED’s or everything. I know with HID’s the 55 watt ballasts sometimes peak more than 10 amps and I have seen them blow 10 amp factory fuses. It’s possible with the fans on the bulbs if the lights are hot enough or maybe something is restricting the fans that perhaps they are drawing more than 10amps or might just be getting a little warm and the fuse is the weakest link so I’m theory if should be the first thing to go. That isn’t always true though. You could test the draw with a mulitmeter or amp meter.

 

With such a low amp draw could be something in the fan that is causing a short.
I would be looking to replace that side.
If something bad is going on the last thing you want to do is increase your fuse size, it’s blowing for a reason.

 

I am probably going to throw one more 10 amp fuse in and 3m wrap the connections just to see if it’s shorting out due to water

 

Exactly what I was thinking it’s gotta be a connection point with a leak

 

Definitely be testing at each connection point and the fuse terminals themselves whenever I get some help lol being in a wheelchair and reaching up in the engine bay using a mirror isn’t my favorite way to spend my time lol

 

Is there a reason water would have gotten into a connection?
Most likely a defective component.
I would ask vendor for a replacement.
I wouldn't replace the fuse with a larger current rating.

 

I would see why it's popping before I went more amps in a fuse. I assume it's the ballast causing a surge. I have the 30 watt ones, no fuse issues, just not that bright. Gonna go hid. You alter the wiring at all, like extend it or shorten it, different gauge etc? You have anything else on that fuse or tapped in there?

 

Ballast in a LED?

 

No idea but im going to give it a shot I mean if I recall I have cleaned the hell out of my truck just prior to the fuse blowing but maybe that’s just a consequence. I’ll go one more round with 3m tape on the wiring harness that could potentially be the issue
