Went out for spin into Wales this morning only for the charging warning light to come on, I pulled over to find oil pissing out of the alternator cover, and its blown back over my boots, the header pipes and the rear tyre

looks like a seal has blown and soaked the alty belt with oil, causing it to either slip or become detached from the pulley wheel(s). Bugger!
Ended up having to be recovered home by the RAC, only a 45 minute wait for the recovery truck so full marks to them.
That’s the first time I’ve ever been let down by my 12S in 6 years of ownership, ah well, 1st time for everything eh?
I’m going to sulk my way through a couple of beers now
