Battery light comes on then off for varying lengths of time. when it comes on the headlights will not go to high and sometimes the radio goes off then comes back on.

Hello,

This could be a problem with Ground #200, which is located near the breakout to the Data Link Connector (DLC) from the wiring harness. The DLC is where you plug your code reader into your vehicle at. Please make sure that this ground is clean, tight, corrosion free, and making good metal to metal contact. I have included a Ground Distribution Wiring Diagram in the diagrams down below for you as well that shows Ground #200 and what circuits ground there. Please get back to us with what you are able to find out, and how everything turns out.

Thanks,
Alex
