I have recently noticed my dash and dome lights flickering. At idle the voltage across the NEG and POS terminal is about 13.2-13.4. When I roll up/down my windows the flickering gets worse. When I crank my heater fan from 0 to highspeed the headlights and radio go out for a split second and my ABS and TRACS light flashes on my dash. I have never really had any battery issues - cold starts are strong.

Can this be a sign of a poor alternator? I only have 180,000 kilometers on it. How can I confirm a weak alternator or other problems? Not very much of an electrical guy. Thanks

I've been having a similar problem recently! Have you found a fix for it?? It's driving me crazy and I can't find any information on it!
