Ok, i thought i saved the site but i didnt and ive searched the stickies and i cant find it, but i was wondering if anyone knew where i could get the directions for testing the coil packs with the Ohmmeter. Let me know...thanks..

 

Not sure which link you had saved.. but here is a recent one from the 5th Gen forums... results should be about the same... since the coil packs are probably close (in function).

It's in the 4th gen sitckys/FAQ's, so it was this site---> www.forums.maxima.org

 

 

stickys are your best friends if you have any of those types of question.

 

ive looked under the stickies, but i cant find it again...

 

Look harder.

 

trust me i am...and i cannot find it

 

I have an idea...


Go to the stickys area...Try "How To's"

It's somewhere ooohhh, say between post # 20 and 22 ... Or around that area.

 

Testing the resistance of coils with a DMM is really a waste of time. The only meaningful reading you'll get is on the low-resistance primary winding and it is not the primary that fails.
Failure in these coils is on the HT (secondary) side and it's caused by the insulation breaking down. The only way to measure the insulation resistance is by using an insulation test meter such as a Comark or (old fashioned) Megger. These devices apply 25KV to the coil secondary and give a reading of the insulation resistance in Megohms.
Even then there are two modes of failure, insulation breakdown to earth - which the IT meter can test - and shorted turns (turn to turn) which is internal to the coil and can't be tested without an oscilloscope.
Overall, the best bet for testing coils is to use a scope and measure the amplitude of the spark waveform and view its duration compared with the others. An ordinary electronics workshop scope will do, provided you use a high-voltage divider probe on the input. Or take it into a garage that has an automotive test machine, the type with a scope, and ask them to hook up the HT circuit and show you the waveform. All six HV pulses should be more or less equal. Of course, it helps if you know what to expect.

 

Best bet is the plug/unplug method.. IMO..

 

I spent 6 months off/on trying to test my ignition coils in every method listed on the board. The issue is so intermittanat that it is a waste of time trying to figure it out. Take my advice and get 6 new coils or atleast 3 and go from there.
