Question Voltage @ idle.

What kind of voltage are you guys seeing @ idle. With my car idling @ 900 to 1,000 rpms mine is dipping as low as 13.3 volts. Thanks in advance.

as low as 13.3? I'd say don't worry about it. If you're hitting 12s, then maybe. A normal voltage is anywhere between 13 and 14.2. Now AMPERAGE, that's a different story.

What kind of voltage are you getting? My car starts out at around 14.1 when I first start it. Then it is usually around 13.6 or lower 5 miles down the road. I am going by the reading on my Commander for the PFC

i usually see 14.0-14.4 at idle/cruise. Stock stereo. Going by the reading on my turbo timer. Headlights/ac/blower and more acc's will drop the voltage about .1v per item i have noticed.

Mine is as low as 10.5 with the lights on. 11.5 normal idle, but that with ALL the underdrive pullies and main crank.

Yeah, unless you're seeing some sort of actual *problem*, i'd say don't worry about it.

My car has a smoking problem, but it doesn't do it all the time. I am trying to eliminate possible causes. I thought maybe voltage was affecting my MOP. But it appears my voltage is normal.
