I have the book at the boat yard I BELEIVE its a selog We been reading the ohms of the parts but<br />we are not to happy with the meters we are using<br />I read some ofyour other post and I would like to know how to test the stator.

hello<br /> stu<br /> do you have a multi-meter and do you know how to use it. also it will be even better if you had a peak reading meter as well. a meter like a stevens CD-77.<br /> post me back and I will know if this is doable by post

Re: 1987 YAM NO SPARK

hello<br /> ok dissconnect the white wire from the CDI. test for spark. if you have spark now test the harness for shorts on the white wire. test the peak voltage on the brown and red wires. should be somewhere about145 v. then test the peak on the blue to black /red should be about 40 v.<br /> do the first test with the wire connected to the CDI. if they fail repeat them discconected.<br /> the stator should have resistance of about 740 ohms from brown to red and 70 from blue to black red. test each lead from the lead to ground. should be open circuit. good luck and post back but I am off for work
