Ruxus Posted March 20, 2018 Share Posted March 20, 2018 Is there any obvious reason that I should check? Not really sure what makes a fuse blow, is it a short or to much load? /Mathias Skickat från min iPhone med Tapatalk Link to comment Share on other sites More sharing options...

Does fuse blow when new fuse is installed (key off) or when new fuse is installed and you step on the brake pedal? You might need lots of fuses to solve this.

Ruxus Posted March 21, 2018 Author Share Posted March 21, 2018 It does not blow right away, it works for a while when I put a new one in.Skickat från min iPhone med Tapatalk Link to comment Share on other sites More sharing options...
Ruxus Posted March 21, 2018 Author Share Posted March 21, 2018 Noticed now that the fuse don't seem to be blown.But both hazard and brake lights don't work.Is there difference between fuses. When I changed the fuse last time I put in a cheap one with a led in it. Gonna change back to the old ones just to be certain.The electric system on these really seem to have a life of its own.....Skickat från min iPhone med Tapatalk Link to comment Share on other sites More sharing options...
carnuck Posted March 21, 2018 Share Posted March 21, 2018 Bulbs both burnt out this time? Trailer harness tends to get rubbed through by the bumper. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
saveevryjp1998 Posted March 21, 2018 Share Posted March 21, 2018 Try the ground inside the driver tail light area after pulling the tail light. Ive had weird issues there before its a quick easy check, should be done periodically anyhow and costs nothing. Link to comment Share on other sites More sharing options...

Kind of odd that your hazard won't work if the brakelight switch malfunctionsSkickat från min iPhone med Tapatalk Link to comment Share on other sites More sharing options...
saveevryjp1998 Posted March 21, 2018 Share Posted March 21, 2018 What made it melt though? Link to comment Share on other sites More sharing options...
Ωhm Posted March 21, 2018 Share Posted March 21, 2018 Was it the Pink wire? 88 wiring diagram. Fuse feeds both hazard flasher and brake switch. Link to comment Share on other sites More sharing options...

My plug melted so badly it was unusable. I just rewired for the Ford switch. Bad switch and I'm done with those. Link to comment Share on other sites More sharing options...
Ruxus Posted March 22, 2018 Author Share Posted March 22, 2018 Yes, what made it melt... my guess is a bad connection. Someone has been tampering a lot with the wires around the fusebox. I found a whole lot of different wire connectors and odd splices under there. It was a black wire that had snapped.Thanks for the input everyone/mathiasSkickat från min iPhone med Tapatalk Link to comment Share on other sites More sharing options...
gogmorgo Posted March 24, 2018 Share Posted March 24, 2018 The brakes and hazard lights use the same filaments in the taillight bulbs, so if the brake light switch shorts out then you'll have issues with the hazard lights. You'll notice if you have the hazards on they'll quit blinking and just go solid when you hit the brakes. Link to comment Share on other sites More sharing options...
