Before you spend $$$$ on a new alternator, ignition switch or headlamp switch!

GMC / Chevy Truck losing internal electrical power while driving. Radio, Dash and all internal power would randomly turn off and back on, flickering the lights and gages and sometimes requiring a jump after the event but never a loss of engine power or control.

This should be good for GM from years 2000+ or a variation of your year depending on fuse location and type as well as body ground location.

Here are the parts I used to solve my issue:
