Re: Coil pack connections info please.
ok, lets assume you have the most common type, a digital meter with a mode selector knob. there will be several resistance modes, each designed for a different range.
the primary winding on a coil usually has a resistance of 2 ohms, so set the multimeter mode to 200. this is usally at the bottom mode dial, at approx 6 o'clock, but it depends on your multimeter.
the secondary winding on a coil usually has a resistance of 3-5k ohms, so set the multimeter mode to 20k. this is usally at the bottom left of the mode dial, at approx 7 or 8 o'clock, but it depends on your multimeter.
primary winding: disconnect each coil pack's connector and touch the multimeter's 2 terminals on the 2 pins of a coilpack, and make a note of the reading you get on the digital display. repeat for all 4 coils.
secondary winding: reomve the coil and measure resistance from the spring that the plug touches to one of the pins (try both, only 1 will give a reading)
a result of "0" or "err" or infinite or open circuit means the coil is faulty, if one is significantly different ot the others it means it is worn and should be replaced.
