    Hi all

    I have a 2014 4900se and just recently my left turn signal has stopped working when all other lights are on. When I turn off the head lights/marker lights the signal will work. But when it is flashing the dash light is fully light and then half lite up. As if it was flashing. The left hood turn housing has been changed. The right signal has no issues at all unless the running lights are on and marker/headlights are off. All fuses and relays seem to be working with proper read outs with the volt meter. At the harness plug that goes up the steering column I get a volt reading of 7.5v on the yellow wire.

    Any and all suggestions are appreciated

    thanks rob

    Did you replace the fender signal with a Western Star or just a generic led? The OEM ones have a built in resistor and the whole lighting system is dependent on sensing proper electrical load.
