So this is the problem, brake lights won't deactivate at all...checked stop lamp fuse and replaced but it did not fix the problem.
The brake lights will only go off when I remove the fuse.
Is there a relay that I might be missing.
Any help would be appreciated
Its on a tractor kw t700
break lights not turning off

nakoBilly Thanks this. -
Yup- the switch on the foot valve is bad- or for some reason won't release. Time to inspect or replace. Could be out of adjustment- if it somehow was moved closer to the linkage, if so it just needs to be moved back.

Check the spike, make sure it's forward all the way.

Have the co driver take there foot off the brakes.
Its going to be the presure switch on the brake valve unde the hood, use a test light to verify its getting voltage to both sides it should only have it on one side when brakes are released. -
Make sure the brake pedal is up all the way too. This time of year a lot dirt and debris can build up at the base of the pedal and cause it to stick or not fully release.

Thanks for the help guys. Will take a look at that switch

make sure the hinge that holds the pedal to the floorboard isn't rusted and just hangin up

Sometimes the foot valve needs a good shot of WD40.
