Howdy guys,
I pulled the coil pack out of my ef because it was idling really rough. I figured it was ignition because when I put my tacko on each of the high tension leads numbers 1, 4 & 6 were about half what they should be. (Remembering that it should read twice as much as the spark plugs fire on both intake and exhaust).

When I tested the coil pack i got 1.7, 1.7, 1.7 on the primary resistance (should be 0.6) and on the secondary I got 9.85, 9.82, 9.7k (should be 9.2). Is the coil pack stuffed? Also I checked the high tension leads and they all read around 16k ohms. Do you reckon these should go?

Cheers Scott

Any help??

Look i'm not a expert on the fully electronic ignition, but....TWICE??? It doesn't sound right that the plugs fire on compression AND exhaust......
What equipment do you use to test the ignition gear? A regular voltmeter doesn't seem like it would do it?

Yeah it throws most people at first, but EF's have a wasted spark ignition. They have three coils to control six cylinders. So 1 and 6 are on the same coil, 2 and 5, 3 and 4. Thus when 1 is on compression stroke, 6 is on exhaust, the coil fires, 1 and 6 both get spark, but since 6 is on exhaust it is a 'wasted spark', hense the name.

So can anyone tell me if 1.7 ohms, when it should read 0.6 ohms on the primary windings is excessive and necessitates the replacement of the coil pack?

cheers
