Testing Coilpacks - Not In Car - How And Where

[LotusGTR]

Uh-oh, coilpack question and only done some limited searching so be gentle. I've got original coils in a box from 2 GTRs I've had so 12 all up. I'd like to know which ones are working properly and which not so I can just keep a tight group of working spares and chuck the dead ones out. I never bothered figuring this out when I replaced each set with Splitfires so need to do it now (spring cleaning my spares).

So, where do you take them for testing and can anybody recommend a place specifically, as close to Dandenong as possible.

Thanks.

Just a multimeter across the two terminals I forget which two and measure resistance. Should be like.8 or something I think?

Pretty sure the resistance will not give any indication of spark ability.

Resistance across the primary coil will tell you if the primary coil is stuffed. If it is, then bin the coilpack. It cannot definitively show that the whole coilpack is good, as there could be problems with the secondary coil, or the core or the insulation.

Also some coilpacks work ok cold but fallover with temperature, so even a bench test wont be 100% accurate.

If you have a stuffed coil chances are the others will not be far behind - get a new set and don't keep old ones for a "spare".
