Thats ok Bryan...sat at my desk in the office today - ill have a look later on [Roo] when i get home but from recollection its set to enable the main light after the bike has started...its just that it starts the full beam...unless i have to re-configure the m-button barrel shaped thingy in the handlebars...

Back in the garage...I can see why my Speedo isn't working....think I'm missing something that bolts to the hub and slots in the Speedo drive!?

Post fiddling this evening I don't think the charging circuit is working as the munit registered 10.4v at 5pm this afternoon after it had been at work all day...something else to check tomorrow.!

Soooooooo, the charging might actually be working.... (im not sure) as theres an munit on it im leaving it on the optimate when its not being used....the checks ive done are....

Run the engine, stick a positive wire from the meter on the battery line.... and im seeing about 12.77v at tickover...if i blip the throttle i see it start to climb to about 12.8....not the usual jump id see from a modern bike...ie 12.5v  - blip the throttle then see it go to over 13v.

Again i grounded the black wire from the meter on the frame and stuck the positive in each of the yellow wires coming from the generator....im seeing about 1.6volts...is that right?

Anymore tests i can do?

I think Bryan did a write up on how to test the charging circuit. Thought it was in Aladins Cave but can't find it. I'm sure Brian will put me right if I'm mistaken.
