cranston Posted Saturday at 07:09 PM Share Posted Saturday at 07:09 PM Hello, I have a VFR750 '97 that has had a reg/rec failure. This has been replaced and the melted plug & wiring replaced. Now there is no spark at the plugs and the fuel relay/pump doesn't activate which would indicate there is no pulse signal from No 4 coil. I've checked the following, and they are all in specification for Ohms and output and continuity: Ignition pulse generators Ignition coils x4 Side-stand switch Clutch switch Neutral switch Continuity between the ICM and the connector ends 4 different ICM units (however, none are "known good") Each produces a signal on the output to the coils Testing the coil output by putting power to the coil and manually earthing the connector produces a feeble spark, but not worse than a new coil. Got to the point of checking astrological charts, mystic tomes, and runes to see if there is anything else that it could be. Does anyone have the knowledge/experience to cast light on the solution?
