[QUOTE="Fred W, post: 1185841, member: 3828"] What a bunch of nonsense. Just because someone was told something by a person of authority [I]who should know[/I] how it works doesn't mean they actually do. The alternator on your FJR, or most other bigger bikes, is also an AC generator (three phase to be exact) that produces AC current, and there is a rectifier to turn the AC into pulsating DC, a regulator to regulate the charging voltage to a nominal ~14.3VDC average, and yes the battery on the bike acts as the filter (capacitive) also. The way that you blow out a rectifier/regulator really quickly is by shorting across the load. That is easy to do with jumper cables. [/QUOTE]
