ps1000 Posted January 30, 2011 Report Share Posted January 30, 2011 Dear members - any advice on this topic would be much appreciated I'm getting an inconsistent and weak spark on my TY250 R Mono. The manual says that the Source Coil Resistance should be 240 Ohms (+ or - 10%) I'm getting a reading of 177 Ohms which is outwith the tolerance level 1. Does a reading of 177 Ohms indicate a problem significant enough to impact starting / running 2. If yes - is replacing the source coil the only solution or is possible that I could repair it Have removed the flywheel cover and there is evidence of dampness and corrosion - so have dried it out and sprayed with WD40. Anything else I should check ? (All other resistance readings are fine) Thanks in anticipation Link to comment Share on other sites More sharing options...
stork955 Posted January 30, 2011 Report Share Posted January 30, 2011 Gday, it is a bit low. This could indicate some shorted turns in the coil. A rewind or replacement is the best way to go. Cheers, Stork Link to comment Share on other sites More sharing options...
