No spark on EFE engined Katana

[Pedda]

Hello everybody,

as the title says, my EFE engined Kat shows no sparks. I measured around everywhere I could, all I know is there should be a spark but there isn't. Changed CDI, still no spark. Is there any measurements I can take from the CDI just ot make sure both I have are not fooked?

Complete loom is also EFE btw.

Cheers

Hmm.. I think the spark test IS the way to test a CDI. But as you've swapped it out with no change of results, it seems very likely the fault lies elsewhere. I reckon using a multimeter any generated pulses should be detectable  though, but I've never tried that myself.

To limit the number of variables (and the loom) perhaps the best way forward is making a bench setup of the ignition system. Pull the coils, signal generator and CDI from the bike and hook them up in a simple circuit a shown on the diagram in the manual. Battery can stay on the bike via leads or use a different power supply,

I put a post in oil cooled about the same thing and @Captn came up with some very good tests 

In oil cooled called, testing CDI and pick ups date 10th April.

Thank you guys. I'll let you know about results.

Maybe best to check the obvious first: ignition switch, kill switch, wiring to and from the CDI unit
