97 - Fuse #3 blows when trailer harness is in
I'm having a very odd issue with my #3 fuse (inside vehicle). Whenever I plug in my trailer lights and I turn on my headlights my #3 fuses always blows - dash lights, cluster lights, and tail lights.
Has anyone had this issue before? |

Something is shorting to ground, most likely on the trailer side since you dont seem to have an issue with it NOT plugged in. So assuming you're not using a brake controller or a 7 way, wiring should be as follows.
http://www.explorerforum.com/forums/...800-jpg.75176/ The brown wire is your culprit as it is all your running lights and what is likely shorting to ground in your cluster or #3 fuse if you will. Best thing to do is unplug the trailer and use a DVOM (digital Volt meter) or an AVOM (analog volt meter) and check the brown wire and anywhere on the frame of the trailer for continuity test. Which if the meter beeps or buzzes [whatever] then its showing a defined connection much like that of testing both ends of a single light bulb. http://www.therangerstation.com/tech...ng_diagram.jpg You will have to either follow the harness and look for a pinched wire or a part of the wire touching the trailer body/frame somewhere. . |

Thank you for the picture. I'll give that a go and see what happens. I'll report back with a conclusion

Sorry for the late response. I was able to locate the problem. I have a 4-round male adapted coming off of the trucks harness. I have a 4-round female plug on my trailer that I use. I bypassed this and hooked up my trailer directly to the truck's harness. Fixed the issue.
Using my volt meter I was able to find out that the 4-round male adapter on the truck is wired incorrectly which is casing the short. |
