I fitted the 150 amp solenoid which I bought off ebay and........the battery is knackered. I had fully charged it with my Optimate but it hardly turned the engine. I am now waiting for a new Yuasa battery.
One thing I could check was to see if the parking lights came on with the brake light and the engine not running - they still do, with the daylight headlamp relay in or out. Naturally, the lights were turned off at the handlebar! I believe Cam's bike does the same thing. Anybody else?
