Ok reluctance triggers Now I get the picture.Bit rare to find people using them now days.A CRO would also check polarity too so that's not a bad Idea.Another issue could be your "Crip" crank index offset which the manual tries to explain but I had to read about ten times to get it right.I eventually found the timing marks on the Harmonic balancer were a mile out.Pays not to trust what you see, always check. With those reluctance triggers you may have your magnet too far away from the coil for it to generate a nice healthy signal.When you see it on the CRO it's not a nice shaped waveform, like you get from a hall effect unit.Can you tell I prefer powered up units. Sounds like the sync is getting through ok as the cranking revs indicate.I would ignore the errors until after you have got the thing started and then make sure they stay away.
