It sounds as if it is a charging problem and I would recommend going to Auto zone they will test the entire system for free.

All dash lights flashing 1994 volvo 850


Very possible bad alternator. Have the alternator tested before you get stranded.

2003 GMC Yukon Denali lights flicker


I have the exact same issue with my '04 Envoy. A friend of mine had a similar problem with his '10 Silveradoo. He had the alternator replaced under warranty - only to have the problem return a few months later.

My advice - don't sweat it. Mine has been doing this since I've owned it (7+ years) with no ill effects really. I can see the lights dim and brighten - and even see the voltmeter showing the changing voltage just like you do.

Sorry I don't have a definitive answer for you - but at least you know you're not alone and it isn't an indication of impending doom.

Good luck!

When car is at idle theres no problem, but when rpm go up all interior and headlights flicker.


Do the lights flicker brighter than they are at idle or dimmer? If they flicker brighter, voltage regulator in alternator is suspect. If they flicker dimmer, you likely have a loose power cable either on the battery or on the fuse and relay center or on the alternator.

BATTERY LIGHT STARTED BLINKING 2 DAYS AGO AND NOW IS ON CONSTINTLY, BATTERY IS 8 MONTHS OLD, LIGHTS DO NOT DIM OR GET BRIGHTER WHEN GAS IS STEPPED ON ,CONNECTIONS ARE ALL TIGHT. ANY IDEAS WOULD HELP.


Is the fan belt tight? If so using an amp. meter, start engine & check by putting leads on neg. & pos. of battery. Reading should be higher than 13.2 if lower replace alternator. Good luck!

Lights flickering


If the light is flickering and not just becoming brighter or dimmer with engine rpm, I'd suspect an electrical short, possibly between the battery and alternator or inside the alternator itself. have the alternator output checked before going further with diagnosis and before it fails completely and becomes more difficult to diagnose.

1994 Ford Tempo alternator light flickered when started


I would not worry about a flicker! If it was staying on, it would be time to do something.
