Electrical Problem?

My Pfive has been acting funky lately. the past few weeks, there has been an occasional hiss/whine from the radio (on or off) when i accelerate. i notice last night that the headlights dim when i hit the brakes, make a turn signal, etc. when the hissing stops, the lights no longer dim, etc. this is on top of the tranny (auto-stick) sometimes throwing me out of forth into third w/o warning. my guess is it's an electrical issue overall, but im not sure.

has anyone else had this experience?
 
Could be the alternator, or the belt that drives it. Could be a dodgy connection on your battery terminals. The hiss could be the belt slipping on the pulleys?
 
the hiss comes and goes..sounds like it comes from the speakers, but even when the radio is off. when its hisssing, the lights dim... the terminals are tight but have some white crust on them, i will clean it off. but what would cause the the car shifting gears on me w/o notice?

that would be you ground. either buy or make your own grounding kit. theres a 'how to' on it.

if my ground was going out, whats the symptoms?
