For no real reason our bus decides to stop having brake lights... we were parked for a few days at the Dover Nascar race. After leaving and driving for an hour or so - We were waiting in line to get on the Cape May Ferry and someone let me know that my brake lights were out... no clue why. Any Ideas... all other lights are fine... red parking lights work... but not brake lights... no stop light on the dash either - I guess I should have noticed that but didn't... '89 Eagle 15 Thanks, John | ||

John, that sound like a switch or the wire broke if you have cruise control and it releases when the brake is applied it's more than likely a broke wire.Eagle doesn't make that switch easy to find it can be under the pedal,at the rear panel,or under the first tunnel run and a converted coach could be any were.Check your breaker panel under the drivers window first to make sure you have current to the switch and relay (yellow wire) good luck (Message edited by luvrbus on June 03, 2008) (Message edited by luvrbus on June 03, 2008) (Message edited by luvrbus on June 03, 2008) | ||

John, My 89 Eagle does this kind of stuff from setting. Driving it makes stuff start working again. The circuit breakers in the drivers side panel sometimes like their terminals cleaned. I just pull them out and put them back in. They are also interchangable so you can swap one you know works and see if that helps your lites. You could also have a dead short somewhere. Look thru all the brake lite lenses to be sure you don't have one full of water. | ||

Dont know how the Eagle does it but on most coaches there is an air operated switch that turns on the stop light.Usually located on an after bulkhead, but? Like any mechanical thing they get old. Cheap to replace. FF | ||

At least one of those switches is located under the electric panel under the driver. Short across the terminals and see what happens. | ||

I found the culprit... I spent a bit of time playing and after removing the dash panel, the back of the switch was labeled #30 and was indeed yellow! I searched around in the relay panel and found the Parking and Brake relay. This wire was labelled #30 and yellow... I switched it with a relay from the front air blower and no difference. More tracing led me to go behind my house battery under the electrical panels and low and behold I found the number 30 yellow on the an air brake controller it was labeled "Park / Stop"... Here is a picture for everyone's future reference. It was the upper right item with the yellow and green wires. The issue was the silly stuff - the nut on #30 yellow wire came loose and the wire was not contacting enough to activate the switch. I tightened it up and lights are back in business... Future preventive maintenance will include lock washers and or some liquid lock-tight on these and some rust repairs on that mounting plate!!! It's an Eagle what can I say! Thanks for all of your great input, without it I would still be searching. John  | ||

John, Don't think I would Loctite those. If you have need to remove the nut the stud may not hold in the various devices. Also, loctite is not conductive as far as I know. If you do Loctite them, use heat on the nut before you remove it. I would stick to star washers. On my GM a nut driver and a few minutes in the electric panels solved several intermittent problems. I think it will be an annual event. Nice pix. Those will come in handy for future reference. Good luck Don 4107 | ||

"On my GM a nut driver and a few minutes in the electric panels solved several intermittent problems. I think it will be an annual event." IF you are careful to re install the toothed washers under every screw head , it will only be every other decade that cleaning the wire terminal ends will be required.I'm at 12 or 13 years and still haven't needed a re doo.

here is one other way that you might like to try and that is to uue NEVER SEIZE on all plastic and copper fittings and the screws on electrialfittings and as fred stated be sure to use the proper washers and in the proper order on the screw or bolt. they will not leak ,shake loose or corrode. use on air lines plastic or copper or half and half fittings, they fasten together easyier and the mess is simple to clean up as compared to thread seal and when you want to seperate they do not break before they come apart. i have used this tip ever since i was given a can of NEVER SEIZE a long long time ago by the shop foreman and have never had a proble again except when i did not use it. even the transite Co in our area, all the fellows in the shop now use it and wonder why i never told them about its use before. you will find it is like a cool beer on a hot day -- ENJOY | ||

the proper washers and in the proper order on the screw or bolt. they will not leak ,shake loose or corrode. The purpose of the star washers is that when the conection is in use , there is some resistance, so there is some heat. The expansion and contraction causes space where the oxidation can do its work. The more oxidation , the poorer the connection , the more resistance , therefore more heat , more expansion expansion and space to oxidise afterwards. The pressure of the star washers solves (at least for a couple of decades) this problem. FF |
