Larry H Posted September 19, 2021 Author Share Posted September 19, 2021 Not much no extra lights or anything daycab tractor just don't have any juice to the marker light side with a test light. Has the old style ground through light combination lights under the door. Quote Link to comment Share on other sites More sharing options...

Larry H Posted September 19, 2021 Author Share Posted September 19, 2021 I didn't know if there might be a common issue with it or where to start getting tires put on tomorrow and need to get an annual done I it to put it to work . If need be I'll just run a jumper wire to them just thought it was weird they both work on the turn signal side 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 19, 2021 Share Posted September 19, 2021 the turn signal bulbs have 2 filiments in them.... 2 different circuits.... the markers are on thier own.... Quote Link to comment Share on other sites More sharing options...
Mark T Posted September 20, 2021 Share Posted September 20, 2021 The ones under the doors ? I thought they were only turn signals in the first place Quote Link to comment Share on other sites More sharing options...
Larry H Posted September 20, 2021 Author Share Posted September 20, 2021 Yeah the ones under the doors, should light up solid as a markerbut don't unless I'm wrong . They have a dual element bulb, two wires into plug and ground through light Everything else works fine Quote Link to comment Share on other sites More sharing options...
Mark T Posted September 20, 2021 Share Posted September 20, 2021 All of my C's ( CH..CL..CT ..CTP ) they were just a turn signal. Same light but only two wires ( and pins ) Quote Link to comment Share on other sites More sharing options...
880joe Posted September 20, 2021 Share Posted September 20, 2021 My 99 CH's are only turn signals under the door I think that's the way on all of them Quote Link to comment Share on other sites More sharing options...
Onyx610 Posted September 20, 2021 Share Posted September 20, 2021 Yup, just a turn signal… Quote Link to comment Share on other sites More sharing options...
Larry H Posted September 20, 2021 Author Share Posted September 20, 2021 Well if that don't make me feel like a dummy, I could've sworn they should have functioned as marker lights also since they had a dual element bulb. Isn't a side marker required? And why two wires to the plug when the light grounds itself. Quote Link to comment Share on other sites More sharing options...
Larry H Posted September 20, 2021 Author Share Posted September 20, 2021 Well thanks for the help I was sweating that!
