Just put my fresh, nice running 350 into my 71 Lark. New Alternator I think 60 or 65 amp, new battery, new voltage regulator, new wiring, just about everything new. When the car is idleing, say at night, why do the headlights and guage lights kind of darken a little then brighten withe the lope of the motor?? I put a new ground strap from the voltage regulator to the tranny to block bolt. Should I have more than 1 strap?? If so, where should it be placed?? Or, is this not the problem at all? Jay
