major electrical issue

[lindjung]

my car is acting strange lately, last night i go to start it, nothing, not even a click, got a boost and it seemed fine drove around and all my gauges dropped to 0 all my lights were flickering, i park and it just died! I figured it was just my battery, so i took my battery to a shop, they tested it and it was fine 13v 600a under load, i put the battery back in the car and everything was working fine been driving all day today without a problem, now that its night time, i can see my cluster flicker every so often, flickers more and more as i accelerate, interior lights as well are flickering, can anyone offer insight? im scared to drive the thing right now!

check the ground cable in the trunk..

both on the battery and the post on the trunk frame. mine snapped off about 3 weeks ago (the post on the frame) I was having similar issues then one day poof car wouldn't start at work and even a jump off the front jumper posts wouldn't work..

popped the trunk (power being supplies by the vehicle jumping me in the front) to connect the jumpers to the battery and discovered the broken ground post..

Your car is a 2005. Has the battery ever been replaced, recent good test or not?
Flickering light can be a sign of the alternator loosing a set of diodes. Have the alternator checked.

Mr. I, you're the best, the ground to the frame was loose, i think my subwoofer may be to blame for that, thanks alot!

Hi all, great forum you have here btw, my lights are also flickering every once in a while I looked at the battery real quick but nothing looked broken, any other reason this might be happening? Also Mr iNCREDIBLE, what kind of grille do you have that has that little hood kind of hanging over the front, looks sweet.
