I have a 1988 Johnson 120 (J120TLCCA)that did run ok untill now. The test that I have done has lead to three things.<br />1-powerpack part#0583489<br />2-stator part#0583410<br />3-timer base & sensor part#0583508<br /><br />All coils have a spark (some what) on the first rotation, then nothing. Only one coil has any spark at every rotation. This spark is very small and only about 1/8 too 1/16 of an inch from the plug wire to ground. I checked all with all plugs removed.<br /><br />How can I test the three parts listed above or should I buy a service manual? <br />I though I would try this site first because experience seem to beat any book.<br /><br />Thanks<br />scg
