Has anyone found a suitable alternative to the Motorola alternator fitted to these 505 engines?
I have just repaired such a Motorola unit by having spare parts from a spare alternator. It did also require a new regulator, as the original literally fried itself.
Experience and evidence from other 505 owners suggests that once the slip-rings become too worn, rectifier burns out etc, the Motorola unit is simply un-economical to repair.
I believe that there is a Bosch unit which can be fitted. Anybody replaced their Motorola with something else?
