battery gauge dipping

ok so here's the short of it. left work yesterday, and on my way out, i jumped a 67 vw bus. his started up and i disconnected and went to a parking spot to add some power steering fluid. when i stopped my gauge for batt. dipped down to 1/3 and the battery light came on. alternator is 1 day old. so working at a parts store i went in and tested the alternator and the battery. both tested good. went out and swapped out the battery and it fixed it. day after... it's back. same condition. battery is an optima yellow top. one thing i noticed today is that the battery is sizzling like it's hot from an over charge. but 2 things, my gauge goes low, not high. and the battery is not hot at all. it's a real quiet sizzle and you have to have your ear next to it to hear it. so what do you guys think? im guessing voltage regulator, which is in the alternator right? and can it be replaced by it's self? it runs and drives fine. only time it does it is at idle and it's only once or twice in a drive. motor only lugs a little when it dips and it dosent seem to hesitate at all when driving. i also noticed that my little connector on the back of the alternator is kinda loose due to the end of the retaining clip being broken, but i wiggled the hell out of it and the only time i can get it to do it is if i unplug it. which every time it does it the connector is plugged in.
