no tractor brake lights

Good point.

 

boy I am stumped now. I never thought of that.

 

I would start by checking the bulbs for the brake lights on the truck 1st and rule out that they are bad.If not than follow the brake light wires back and check for a break in the line. Odd that both brake lights on the truck are not working.

 

Get a wiring diagram from super miller and start tracing wires with a multimeter. I'd narrow it down to being in the cab or outside the cab first. Sounds like a bad connection somewhere.

 

Start with the simple 1st….check to see if its the bulb 1st with a fresh light….a please don't be like lots of people on here who ask mechanical questions and NEVER update us as to what fixed the issue!!

 

Cool........!!!!!!

 

Very common problem and wear item involving brake lights.

What threw me off was the statement that the trailer lights were still working..

Being a good mechanic is years of experience and 80 percent diagnostics.

Whenever I have a friend who asks me what they think their problem is with a vehicle I ask for a couple previous month history and go from there.

Just like a Doctor, Early Symptoms can tell you a lot about the present problem.


So next time you have a problem state the make and model and year of the truck with the miles and this allows some who knows something where to begin to diagnose the problem as what is the condition of the patient.

 

Glad you got it figured out. Thanks for replying back with what fixed it.
