Z1 900 Regulator / 21066-013


Product Description

Z1900 Regulator Rectifier 


Equivalent to OEM:

  • 21066-013

Fits Your:

  • 1972-75 Z1900 

Please read this information carefully before completing your purchase.

The Z1 regulator is basically the same item as the other combination
regulator / rectifiers that we sell for the Kawasaki's with the exception of
the length of the wires.

  • Buyers should have no trouble installing the rectifier 
  • it mounts to the bottom of the battery box, where the original voltage regulator was mounted
  • won't fit  where rectifier used to be 
  • Once mounted, the wires plug into it just like the original components did.


The black wire from the new unit (the ground) - MUST be connected to the negative
battery terminal.

Trying to ground it anywhere else, or any bad ground can cause the unit to catch on fire (really)


Please contact us if you have any further questions.
