break lights not turning off

Check the brake lite switch can't remember on a kw been a while but I think its under the hood near the foot valve hand brakes not on is it?

 

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.

 

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.

 

Are the T700's different from the rest of the KW's? Everyone I've ever seen was on the inside of the firewall behind the dash panel. Either way nakoBilly it probably looks like this and Bill is correct it should only have power to one post with the brakes released.
