I bought a 2000 Tiburon from a friend recently. it had a sound system in it, but was recently taken out before the sale. since then all lights (cluster lights, tail lights, break lights, head lights, high beams, dome light, clock, radio) all flicker. it only noticeably happen when the car is idling. the car starts up fine, doesn't die off, leading me to believe that when he took the sound system out he knocked a grounding wire off a bit. he also bought a new battery and the alternator was replaced less then 50k miles ago. where do I start to check??? ... or could this be worse problem in the making...?

First off - 125K mi is nothing on that car (as long as you maintain it). The alternator is actually also the voltage regulator and this aspect of the alternator frequently fails before the actual alternator itself does and causes irregular voltage - so it makes sense you drove without the battery connected but you probably were having irregular power instead of a nice steady 14V (the other thing to know is that even if they do show 14V all the time the amperage may differ, both problems = change the alternator).

sounds like a ground problem. there is more than 1 ground wire on them

it does sound like the alternator but i would get the battery charged and then have someone to check the charging system and the fuses......get the battery charged first so they want try to sell you a battery and an alt. cause there are a few people out there that want to take you.....

the alternator gets power on big wire battery voltage the wire runs to starter, fuse box .alternator fuse goes to automatic shut down relay to relay control in ecm/pcm the field wire comes from ecm /pcm to alt.other field goes back to automatic shut down relay back to charge battery . if not charging at alt. try new alt. and retest.
