ignition coil

ignition coil

sun is now out so time to get the Falcon 74 out. No spark! The insulation on the original looking wire from the points to the coil also original looking had brocken down . I replaced all the wiring up to the rectifier.
The bike started after a push . It ran fine , good spark , charging all fine . The problem now is starting . Is poor starting a symptom of the ignition coil being on the way out ? or do they just stop working? Is there anyway of testing the coil or is it worth just replacing it?

Coil problems

Post  piston 197 on Sun Apr 17, 2016 10:33 am

Andy poor starting , especially when warm , can be attributed to ignition coil/ flywheel
The Flywheel when placed on a steel table should require around 30Lb pull to pull it free, can be checked with a spring balance, Villiers services will re-magnetize for you if this is the problem?
Coil similarly will start to break down and give a weaker spark when hot
Best bet is to check flywheel magnetism and replace coil, at least you know all components are good then .

Thanks John, have checked flywheel . Magnets are good if my fishing scales are working as they should . Looks like a new coil or time to do the 12v conversion.
