Anybody seen this before on the Beaver upgrades? Friends went Sat, 2nd time in 2k miles/2 months. Hes no idiot on electrics and everything's installed as should be. Main 30 amp fuse from reg/rec to battery. First time it went was put down to the newly rewound stator (300?miles) burning out. Replaced with a low mileage OEM one. Coincidentally we know of another one doing exactly the same on the same day.
