I have a 2000 ford ranger. All lights work fine on the truck but when I use the left turn on the trailer, the turn and brake sighal don't work. I checked the bulb it is ok. the vom metter showes flashing voltage at the trailer bulb wire but it will not go on bright. Could i be getting only partial voltage and not enough to light the bulb? I also checked the pigtail at the truck and the pin for left turn will not light the bulb. HELP THANKS WALT (DUNITALL)
