Rear Brake Lights

 

[Here's some recent info via the FCOC Yahoo discussion group - ]
I had hazards, turn signals and tail lights, but no brake bar, no brake lights, no engine brake light.

The problem was diagnosed by the F-liner help desk as being bad diodes. 

The problem was neither Fliner nor Winny could tell me where
they were located.  Well, we found them.

So, for those of you who wanted the info, the suspect diodes are
located at the base of the steering column, in their own harness which
is about 9" long, 1/2" wide with spade connector clips on each end.
The good folks at Sterling Truck in Tallahassee found them and they
were cooked!  Ordered replacement o-night from Fliner, snapped in the
new 9" segment and Voila!  Brake lights again!  Fliner picked up the tab for both parts and labor.
So there it is, FWIW.

Editor's note - According to FCCC tech support, this problem was mostly 1997 - 1998 model chassis. The original design used only one diode that sometimes got overloaded and blew out. The design changed in 1998 and a 2nd diode was added making this problem a pretty rare occurrence.
