I was helping a friend this morning who has a Yamaha watercraft (Jetski?) that will rev out but has lost power. Idles and revs fine, but no muscle. In the course of poking and prodding, I checked the CDI module with a multimeter and had many resistance measurements that were out of whack with the Clymer manual we had to work with. The Clymer manual has a matrix of wire combinations to check and expected readings to have on the meter. The wire combinations that should read open when checked did, but the resistance readings where all way above the book ranges (I.E. book says 30 to 40 kilohms, read 3 megohms). Same results using another meter, and both meters checked ok with known resistors. I could see having one squirrelly reading, but all ranges were out of parameters. The stator and coils read ok, within spec values. Anyone with experience checking CDI's have any suggestions?
