Marker Light Question- M812 Do I need a new 3 way switch???

[Andydieselpower]

On my M812 all of the marker lights (back & side) work except the front two which are part of the blackout/turnsignal assy. When I use my 3 lever light switch to turn on the marker lights none of the marker lights come on. When I flip the switch to head light operation the head lights and marker lights all come on with the exception of the front marker lights.

Do I need to purchase a new 3 lever light switch? Could this be causing my front marker lights to also not operate?


Thanks again for your help,
Andy

Your front marker lights don't operate in the service drive mode, only the headlights. Subsequently when you put the light switch in the park mode, your front markers and rear tails will be on but nothing else. It's the way it's wired.
