I have noticed a odd flick in my headlights at nite which happens for a fraction of a second,i don't notice in the day time on the instruments ,it charges good(14.5 ) it is like a load suddenly hits then gone? Any ideas.

Could be the e-fans cycling. That's one hell of a draw when they kick on high.

stock are aftermarket stereo system are you idling when this happens

No it is not the e fans and it has a stock stereo, it has done it for years and it is just annoying to see the flick at nite,thinking something could be wrong. It may do it in the daytime but cannot see the headlight flick. The volt meter doesn't change that i can see,all connections are clean and tight,just wondering.

its normal
best guess you only see it at night right
when your driving around after its gotten dark for a bit all your lights and everything has come on so your pulling a wii bit more current and i believe your ecu compensates slightly by adjusting the idle a tad so there is a brief ficker

My 02 yuk has been doing this as long as I can remember. The electricals on this vehicle are not the greatest. There was a electronic gizmo I wanted to install years ago but was warned about voltage fluctuations in this series of vehicle.
