Ok so the stop lamps on both sides of my bronco keep going out as well. but it keeps blowing my fuse... I pulled the lights off the back to check to see if i had a break in the wire but no such luck... any suggestions... Oh and it is a 1986 bonco ii...
yo John,
Here is some info that is same as in Ford EVTM for your 86 Bronco II

Fuse panel wiring diagram
Shows Fuse #5...is this the fuse that blows out?
Brake/Turn, etc.

Best way to find a short is to isolate the entire circuit from Panel to brake light connector and socket;
disconnect connector(s) along path from flasher, multi function switch (MFS, aka turn signal stalk),
SHORT CIRCUITS
Never use a self-powered test light to perform checks for opens or shorts when power is applied to the electrical system under test. The 12 volt vehicle power will quickly burn out the light bulb in the test light.
1. Isolate the circuit from power and ground.
2. Connect the self-powered test light or ohmmeter ground clip to a good ground and probe any easy-to-reach test point in the circuit.
3. If the light comes on or there is continuity, there is a short somewhere in the circuit.
4. To isolate the short, probe a test point at either end of the isolated circuit (the light should be on or the meter should indicate continuity).
5. Leave the test light probe engaged and sequentially open connectors or switches, remove parts, etc. until the light goes out or continuity is broken.
6. When the light goes out, the short is between the last two circuit components which were opened.
Our 96's right brake/stop/signal tail lt. assy's wiring harness was chaffing along the passenger side fender panel's sharp edge - where it enters the assy; take a look
