So yesterday evening I decide go to for a quick fang through the nasho on my Triumph sprint. Stopped at my usual servo for a fillup then off I go. Get to bald hill and stop for a bit. Hop backup on turn the ignition on, pull the clutch and hit the starter. Nada, zip, nothing. Ok, turn off, flip the sidestand down and up again, try again. zilch. The lights on the console but nobody home. Tried a few more times then I started noticing the headlight looks kinda yellowish and a few more goes the LCD on the console wasn't showing any info. Looks like dead battery, so I called for a tow. Got home and tested the battery, 9V. Jumped it from the car and it started right away. Check the battery with the engine running, 11.7 volts (was charged by the car engine for a while before starting) and decending, not rising when revved. So battery is fine, charging system is broken. Will test in the morning but from what I've read, the first culprit is the rectifier/regulator, so ive hunted one day from a wreckers. Hoping its just that and not the stator.
