The 77 B1 and C1 use a 3-phase excited field alternator and a separate rectifier and regulator - this system is unique to the 77 models and can not
use the later model rectifier/regulator - nor can the 77 rectifier and regulator be used on later model 650s. The separate 77 rectifier and regulator are no longer available
from Kawasaki,
The CSRs (and a few other late model 650s if I recall correctly) use a 3-phase permanent magnet alternator and a combined rectifier/regulator. This rec/reg is also
still available (at least as aftermarket) and can be used on all 3-phase permanent magnet models.
The easy way to tell what system you have:
- 3 yellow stator wires plus 3 bolts in the center of the alternator cover plus a green wire from the regulator to the field coil = 3 phase excited field system
that requires separate 77 rectifier and regulator.
- 2 yellow stator wires and no bolt holes in the cover = 1 phase permanent magnet system that requires a 1-phase combined rec/reg (used on most of the 650s from 78 and up).
- 3 yellow stator wires and no bolt holes in the cover = 3 phase permanent magnet system that requires a 3-phase combined rec/reg (used on the CSRs and possibly a few other modesl).
Hi Yellow lifted this from a Yank forum,seems you have a combined reg/rect suitable for use with Z1 type permanent magnet rotor ,seems you have the green wire as the unit you are using has the seperate exitation field.it states above it needs separate 77 reg and regulator...Hope this helps Paul J
