Title: Boyer micro coil connectors - source for replacements
Post by: paulbaker1954 on May 27, 2019, 08:38:36 AM: I need to replace a couple of the ignition cables on my bike which has a full Boyer kit with micro coils

Trouble is I can’t easily find where to source replacement brass connectors that push on the coil terminals

Can anyone advise where I can get them ideally on fleabay

Thx saw those as well but can’t see how the inner core wire gets fitted/crimped. Maybe I am being dumb!

Strip back the insulation so that the internal conducting wire is long enough to fold back over the insulator and crimp the conductor wire between the connector and the insulation.

Thx I thought that was it, it's a long time since I have played with "old" ignition stuff!! The connectors that Boyer supplied were different and required soldering etc

Post by: paulbaker1954 on June 17, 2019, 02:04:06 PM: For the record got replacement from Boyer at 82p each.

Turns out the Boyer Micro coil pins are 4mm diameter so the standard 7/8mm fittings are not much use and I had no end of trouble finding any 4mm ones anywhere
