Can Spark Plugs Drain Battery. Can old spark plugs cause. If the car is garaged you can remove both plugs.
Remember that the drain doesnt have to take your battery to zero overnight just low enough for it to not start. The answer for automotive spark plugs is no with a normal battery. But I fear that something is shorting out somewhere to cause the drain while ignition is off.
Just hold the testers probe near a plug wire or even near a coil-on-plug coil assembly and you can tell if the plug is firing.
But with a 9v battery by stepping up the current using a ignition coil which ramps it up thousands of volts then you will be able to use a spark plugOnly thing with that though is that your battery 9v wont last. If car is not garage you can drill a hole in the plug big enough for water to drain out. Can old spark plugs cause battery to drain. I go on my merry way to Autozone to return the spark plugs that I bought.
