2004 Nissan Altima 3.5L BATTERY LIGHT went on during 15 minute drive. Next day car "died" while idling after a 20 minute drive. BRAKE WARNING LIGHT & BATTERY LIGHT on prior to full electrical failure.


Start with checking the alternator voltage with a multimeter. With the car off check the voltage in the battery which should be holding 12v charged less if flat of course then start the car and test the battery again. If the alternator is good you should be getting a reading of 14 to 14.5 v if it's the alternator it'll A) not put any charge into the battery or B) be a very low voltage being anything under 13.5 v

You have to find the reason the check engine light is on. This will aid in diagnostics. Also, are you buying fuel at the same place both times?

Check the vacuum line on the fuel pressure regulator for any sign of gas being sucked into the line. A failed regulator will let extra gas get into the engine. If it's okay, have the fuel pressure checked. That's sure a lot of gas, way too much for the engine. Good luck.

I don't think the rough running had much to do with oil level, since it started running rough a 2nd time. Check the fuel filter and ignition timing.
