Set DMM to "AC Voltage" 100v scale, measure between each pair of yellow wires coming out of the engine. 1-2 2-3 and 3-1 (polarity doesn't matter...). Should have 60 Volts AC at 5000 rpm.

Just got already for a nice ride and it happened again about 30 mins from my house looked down and noticed the digital display was flashing and the speedo pin was going mental pulled in it went away thought meh carried on got a minute up the road and it died for 5 minutes. Got it started and rode home quick.

Just got back and stripped off the back plastics just about to try the above out.

Right my multimeter doesn't have a 100v scale and I'm not entirely sure it was set to AC but I used it on this setting

and got 0 at each pair of pins

Wrong setting, turn it clockwise one click. It appears that's the DCV setting, so averages out to 0v with AC.

ooook something a little wierder just happened.
Went to try the above again turned the key noticed the digital display was off (everything else looked normal) decided it must just be low on battery; thoguht I'd see if it'd start. But it just locked on the ignition, kept trying to turn itself over even though I'd released the button. Turned the ignition off but it still carried on trying to do it, disconnected the battery and it stopped. Reconnected the battery and it's carrying on!

Tap the starter solenoid with something. The contacts have stuck.

Where's that? Not around the bottom of the front cylinder area is it?

I've heard they go often on sv's actually :scratch: or atleast I think it was the starter solenoid.

Starter solenoid, under the RHS seat infil panel where the main fuse lives.

gah I hate this bike, gave the starter sole. a tap, solved the issue (ta). But turned the key in the ignition and everything was completely dead, gave it a min turned it off and on still dead. Decided it was a fuse, checked the main fuse - looked ok (thankfully as I've just found out I don't have a spare), checked everything else all looked ok went to try it again and it worked!

At 4500rpm the three pairs of terminals had 75v
