Turn signals stall Cummins 330

[dxstrob]

Have a 2006 Discovery 39V. When I engage the turn signals (right or left) with the front lights on, it will stall the engine. If I turn on the emergency flashers it will stall the engine. If the front lights are not on the turn signals will not stall the engine but flash together and not separately. Turning on the headlights turns on the rear view camera. Break lights do not work. Help.

Had you done any service work prior to this problem starting?

Make certain that the chassis battery cable connections are clean and tight, the voltage is at 12.75 and chassis batteries are in good condition. Make certain the chassis battery disconnect is turned on. Let us know what you find.

Good luck finding a solution.

My WAG is that a ground wire at your ignition switch needs tightening or a new ground connection.

I would guess a Battery going bad or the bad ground -

I know it sound crazy but check all fuses, a blown fuse can cause this. I had a similar issue, when I put the brakes on, the dome light and dash light would come on. found blown fuse, no figure.
