Welcome to TRS
Assuming 1992 Ranger
Turn on 4-way flashers, if they work then turn signal wiring is OK
What is the number of the fuse?
Cab fuse box diagram below, 1991/92 is the same
If its fuse #5 then it powers Turn signals, but also reverse lights and Master's brake fluid level sensor
Unplug the Brake fluid sensor, see if fuse blows
Unplug the Reverse light switch, its on the transmission, manual or automatic matters
Unplug the Flasher, the round unit in fuse box
Thanks a ton for the info! Unplugged the sensor on the tranni and now they workWelcome to TRS

Great thanks a lot!Good stuff
Could be a bad reverse light switch or a shorted wire or bulb at the rear
Test with OHM meter is best
