Thread: Electrical power cuts out

I would check all major wire connections (battery, starter, alt, ect) for corrosion and tight connections. I would check ALL fuses inside and under hood to make sure non is blown but also to make sure they are fully seated and not flopping around. I would also wiggle the ignition key the next time it happens. It sounds to me like something is loose.

I had a problem:

Radio cut off, windows quit working, gauges quit working, lights would cut off when I hit the brake, other weird stuff.....

I purchased an ignition switch because all symptoms lead to that. Before I installed it I checked my battery, I pulled the positive terminal off and it was gummed up. I cleaned it all worked fine. If all your stuff is new, maybe something didn't get tightened down. If you are hearing "sounds" around your belt area (beside your battery) you may have arching at the terminals. But as falcon said, check terminals, grounds, the lead to your alternator, ect..
