Weird Electrical Issue

[s13_slider]

Hey, guys. I have an S13 Hatch with an S13 blacktop SR. The other day, when I would step on the brake pedal, the speakers would lose power for about 2 seconds then come back on. All the lights(headlights, cluster lights, turn signals, etc) would flicker and come back on. Also, when the car gets turned off, everything loses power. The lights, clock, and radio will turn off for about two seconds then turn back on with the clock back at 1:00. I checked the battery terminals to make sure nothing was dirty or loose and actually found the negative terminal loose. I tightened that back down, but it didn't help at all. The battery, by the way, is in the back of the car, but it's been there for a couple of years. Does anyone have any suggestions on where else to look or anything like that? Thanks in advance!

Sounds to me like either a ground is loose or a wire is shorting and it only happens under braking. Probably it is getting pulled in the wrong direction when you brake. Check for loose terminals in your main fuse box.

have you done an AVR test on the battery and the charging system?

either you battery is toast or the altenator is unable to produce a stable charge if no fault is found with grounds.

hope that helps

I was gonna get those tested today or tomorrow. I don't think the battery is toast.. it's pretty new.. but I'm gonna get it tested just to cross that thing off the list. Til then.. I'm gonna check all the grounds and such. Thanks! :)

Let the car run and jiggle every single wire and connection with your hands. See if you touch one and the car starts losing wire. You can get lucky and find your short that way.
