I don't have an exact for your model but resistance issue will be very easy to spot as when you test you will get usually zero as the reading if faulty
roughly speaking you would expect 240 - 380 and 720 - 1000 and 40 - 66 on the three pairs of wires coming direct from stator if you get zero as the reading on any of the 3 pairs then the stator is the fault... Rarely does the coil pack fault without impact or over heat but for the coil pack 0.08 - 0.10
let me know if you need clarification on testing ... Good luck!
