Turn Signals Blowing Fuses

This is for "general" electrical discussions. Audio, security, remote start, and power accessories should go here, since they don't seem to fit anywhere else. Not for diesel-specific (like glow systems), or gasoline-specific (like ignition systems) topics.

Turn Signals Blowing Fuses

Postby Pupfocused » Tue Jun 27, 2017 2:33 pm

On my 85 pup the turn signal fuses have started blowing. They do not blow instantly but every few days. My guess is there must be a bad wire some place. It has been extremely warm recently which may or may not be a factor. Any ideas where to look
Thanks

Jim, does the fuse blow usually when you turn your lights on? When you hit a bump in the road? When you push in the clutch? My 1st guess is a bad bulb.

If it has a trailer wiring connector check that as well ...

The lights have not been on. I have not seen the fuse blow. I will be driving and realize that I do not have turn signals. I am watching more carefully each time I use the turn signal to see if happens turning right or left. I put a 15 amp fuse in last time since it was all I had.

Take a quick look under the back of the truck. Inspect the wiring there. It could be someone in the past hacked the wiring for a trailer plug.

Also, you can remove one screw from black air duct under the dash driver's side. Remove it and look around the harnesses around the steering wheel and pedal assembly. I once had a short there in my 85LS. To see if the harness has rubbed a bare spot. Check the wires going to and from the flasher units. One for 4x and one for turn only.


Bad bulbs do weird things. On a two filament bulb, one filament may touch the other and short things out. In your case, turn and parking light share the same bulb in the front amber bumper lights.

Just some ideas
