Can't afford a Cycle Electric ?

This is still basically a "one-wire" set up.  The little Bosch can be adjusted to suit your output needs by bending (some have adjuster screws) the contacts slightly.  Too much can boil your small chopper battery, so tune it down to 12.8-13 volts.  This type of regulator bracket can be spun around, etc . . . with extra holes to help get your regulator where you want it.  Up front like this, it catches air and keeps everything cool.  Unhook a single wire(hot BAT wire), and generator can be easily removed for service.
