Customer Question

Have a peterbilt with some marker light issues.
2014 s/n: 1npcxpex6ed248320.
Marker lights work when truck is stationary without issue. Once you start to drive the breaker trips and markers go out.

Hi I'm Wayne

I will help you with this

question :::

does it do it all the time,

without trailer does it do it

let me know please

Customer: replied 1 year ago.

With or without trailer. Lights stay on if parked or engine off. As soon as you start driving the circuit gets overloaded and trips. The woring appears to be good nothing rubbed at pinch points etc.

and touching to ground
