Weird electrical issue - Brakes hit = power loss Options

[k-weaver]

Alright guys so here is the story...

I was on my way to work this morning and everything seemed fine. I hit my brakes to slow down for a corner and right as I did so my stereo turned off, my clock reset, and the car stuttered for like a half a second. After a brief "what the hell was that?" I turned off my radio (thinking this was a possible cause) and kept driving. The rest of the entire drive I noticed my dash lights (more so my clock) would dim ever time I hit the brakes. Its as if the voltage is dropping drastically for a split second but then going back to normal.

I've yet to do any troubleshooting as I'm currently at work. Just wanted to see if anyone had any idea's that I could try out once I get home.

Bring your car to an Advance Auto Parts or a Autozone and have the alternator tested. It sounds like your starting to see signs of strain.

Have them test the alt, battery, and to see if there is a drain on the system (with an amp clamp), because it could also be something shorting out. Luckily our cars electrical systems are pretty simple, so a resolution shouldnt be too hard to find.

And one more thing to check, see if your brake light switch may be pressed up against the firewall. If the wires have been crushed fir long enough, they may have worn through the conduit and are contacting the firewall as you press. Usually this would result in a blown fuse, but it's something to check as well. Your brake light switch is located behind your brake pedal in a bracket near the base of the pedal. Looks like a white box with a nipple sticking out.
