    Default Flickering lights

    At night I notice my lights ( interior, dash,headlights,radio ) flickering. It does it when I hit a bump and really does it when I let go of the accelerator. I had my alternator checked and it's good. I'm baffled. I made sure the battery ground is good.Its an 85 Sierra.

    I figured it out. The engine wasn't grounded to frame.
