Hey guys, got a technical question.
How many volts does it take to start a car, would it be 12volts?
My S15 wouldnt start this morning, the Apexi turbo timer was reading only 10 volts, so just thinking that the battery was flat and it wouldnt start?
Any help would be great.
12.1 @ 116
QR Sprint - 58.4
QR Clubman - 61.8
Lakeside - 63.1 (first time out)
Paul - I've had the same problem in my car, and the S15 won't kick over on 10v.

if i remember correctly from trade school if thebattery voltage drops below 10.6v it want be enough to start the cer
This is pretty much correct.
The amount of draw that the starter motor uses to crank the engine over requires the battery is holding decent charge.
Time to grab some jumper cables and sneak your car up to an unsuspecting BMW driver.
Standard battery should be 12.6V, even though everyone pretty much refers to it as 12V.

starting a car usually runs a 12v circuit, then when the car is running, the ignition runs of a 6v circuit.
Older cars with points ignition run the ignition off 6V, more modern cars with elctronic ignition run 12V on the ignition circuit.
