Trailer is Blowing Fuses After Switching Over to LED Lights

Question:

I changed my trailer lights to LED lights and now I keep blowing fuses why?? I’ve double checked all the wiring and it’s good

This sounds like you have a bad ground or, more likely, a short somewhere. When swapping over to all LED lights, it is important to have separate ground connections for each light. This is a commonly missed step and can definitely cause this to happen.

Shorts can he hard to find and will require the # PTW2993 tester to locate. I know you said the wiring all looked good, but I would still run through everything to make sure all the connections are solid and not touching each other where they aren't supposed to be.

If this has been done, or it does not fix the issue, let me know and we can try something different, but this should get you up and running properly.
