Until today my bike started perfectly - one press of the starter motor and she purrs into life.
Whilst out on a ride today, I stopped at a shop. Starter swung over as per normal but bike would not start. After a few attempts it started like usual and ran perfectly - also as usual. About 10 km later when I stopped and switched her off, she refused to start and I had to suffer the indignation of a tow-in home ;D
Back home I started trouble shooting. Did not take long to rule fuel issues out - everything was working as it should. Turning my attention to spark I discovered that the spark plugs were not firing - whether I unscrewed the plugs, kept them in the cap and held them against the engine, or whether I stuck a screwdriver down the throat of the cap. Nada nothing.
Now to work out the reason - take my multimeter, the manual and start testing-
1. Test the continuity in the connection plug to the coil and between the two spark plugs - correct as per manual.
2. Test the generator coil continuity - correct as per manual
3. Test the power sorce coil and pick up coil - correct as per manual
4. Test the CDI unit - resistances beteen the terminals is as per manual.
5. Double check the sidestand and clutch cut out switch mods - still functioning correctly.
6. Check the kill-switch and ignition switch - functioning correctly.
7. Check the two 10A and the main 30A fuses - all intact.
Then I check the regulator - get no resistance readings whatsoever between the terminals. Look like it is toast.
But can that lead to no spark? Whilst troubleshooting I had the battery on charge with the result that the battery was fully charged and the starter motor was turning the engine over normally when I gave it a last try.
So I am stumped at the moment and will appreciate and input and help.
Thanks.
