Working on a 86 R688 ,keeps blowing stop/turn fuse cant find short, this is one that the park brake turns stop light on but where is that switch? Thanks for any help.
Are you saying the brake light circuit works fine using service brakes, but when you pop the parking brake knob, it turns on brake lights and blows fuse?
well not realy it all works fine most of the time maybe 2 or 3 days then pop no turn sigs,not sure what is doing it yet cant get it to do it in the shop but you got me thinking and it does it on the road not when park is pulled. i just found that the same fuse powers the stop light switch and the flasher , thanks to both of you. Yes Bill it helps because i forgot the pressure off ones.
There is one more thing.I had a 98 CH that the stop lites and turn signal worked thru the turn signal switch on the steering column.Not sure what year does this.Only the ones I had trouble with which was twice one signal wouldn't work.Not sure how you would check this for a short unless wire was rubbed bare and toughed bouncing down the road are turning steering wheel.
found the switch on the park valve unpluged it, works now but who knows ??? hey Bill my buddy got a 1974 pete 359 with set back axel, first for me to see one RARE thanks
Well glad I was helpful. KW came out with a self cancelling signal switch for a short while.Contacts wore to where one lite didn't work.Took a plastic coffee lid and made a shim.Guy sold the truck said it was still working.I had an air leak a while back under the dash.Thought it was parking valve but it was the same switch your having trouble with.All these new thingamajigs and do dads make if fun to trouble shoot. I have seen a few.set back axles on a Pete.Rather have the long hood with regular axles
