Trailer Keeps Blowing Fuses on Tow Vehicle

Published 07/27/2017

Question:

Thanks for your response. I am not sure if I understand everything you said though. My trailer is blowing my auto fuses. To the best of my knowledge and your advise, I need to check all the lights on my trailor to see if any of them are going to ground. Is there any more advise you can give?

You are correct, if you know that your trailer is causing an issue with your fuses blowing then you will want to check the connector, wiring, and the grounds.

Make sure that the connector is free of any debris or corrosion. Clean it anything out that might be there and apply Dielectric Grease # 11755 in the connector to help keep it clean and in proper working order.

To check the wiring you will want to look for any places where the wire has been bent, damaged, corroded, or has exposed wiring. You will want to replace any wiring that has any of those symptoms.

For your grounds you will want to check to make sure that all of the grounds (including your lights) are secure and connected to clean, bare-metal surfaces. Even paint can cause issues.

If you have done all of this and are still experiencing issues then it would probably be best to take it in to a shop so that they can physically inspect it to find out what is going on.
