coil tower ohms

[TurboToy]

was checking voltages on some sensors to be sure i am right on the #'s and started chevking my coils, started at the left and came across had 11-14 ohms till i hit the last set on the right and nothing went back and checked again same results. does this mean the coil pack is dead and in need of replacement? any help will be great.

That is probably a good indication. Ohms (resistance) may be so high it will not read. Turn the setting up one (if set on 20k, turn to next highest, like 200k) and see if you get a reading.

They should be between 11-13k ohms on each coil, checking towers front to back.

HTH.

Resistance is only an indication. I have seen packs with low (11.xK) that wasn't good. IMHO the only way to be sure is with the Casper tester. (Shamless plug)

I think resistance might catch 50-75% of the problem coils...I agree the Casper's coil Tester will probably get you to 95% anyway. Mine sure is handy.

If you were reading front to back across each coil and found one that read zero. I would think that is a pretty good sign that it is bad.

seems to have helped

i replaced the coil pack today and it seems to respond alot better i still have some knock but its little stuff and i have alot more tuneing to do but the prices have come way down on these things i was thinking it was goin to be a cupple hundred dollers but it was less than 75.00 for the coil pack, that was cool.
