Okay, Here it goes.... I am working with a `86 Johnson 150 GT with VRO. We noticed the engine running a tad bit rough, Loss of power/speed, Like it were missing a cylinder or two, and decided to do a few tests. My first assumption is this is an ignition problem because the starboard 3 cylinders are A LOT more cooler than portside cyls. when I run the engine for a few minutes(and I am assuming they are getting little fire) I used a large capacitor and absorbed the spark from each cylinder. When I absorbed the spark from the top port side cylinder coil and the engine started running smooth. I came to the middle starboard coil, and when I absorbed it's spark, The engine RPMS didn't drop, or no fluctuation in sound, or anything else noticable. I have did resistance test in the sensor coil, charge coil, stator, and all that checks out fine. I checked the kill-wire to the power packs, and those are fine. I am not sure what else it could be.
ALso, Keeping in mind that I do not have a DVA Adapter, and can't measure the primary line, or the high tension line on the coils. If I had the correct equipment, there's more I can check, but keep in mind that I do not. I've just been doing all the workarounds I can do. :-/
