so i just got my mk3 suppy running and i got it charging right and everything, but there is one more thing that is wrong. the car was sitting for a while, but any ways when you turn on the headlights.....the dashlights and the headlights will flicker on and off.

i do hear a clicking relay behind the dash but it kinda hard to locate when you are kinda pissed off. have anyone ever had this problem? or do you guys know a fix for it!
thanks for your time
