Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.
Problem
Effective with the machine serial numbers listed above, LED signal lights were used. On some machines the lower LED voltage draw will not operate the flasher module for the turn indicators in the cab. The turn indicators in the instrument display stay on solid when the signal switch is activated. The signal lamps outside the cab work correctly and blink when the signal switch is activated.
