1978 KZ1000 Project

That doesn't have the model # on the side. It might be a cheap Chinese knock off junk. 

rstnick post=907481 userid=2777I was reading about the Shindingen SH775 Regulator Rectifier combined unit upgrade for the older KZ/Z's.
Will something like these modern SH775s work?

Voltage Regulator Rectifier for 760cc Polaris 800 Ranger SH775 2011-2014 ATV | eBay

That is a cheap Chinese Repop. I think you need to put the search word "genuine sh775" to get the real thing.
Look for a good used one on Ebay. Anything worth buying is going to be +$100 Canadian by the time its received.

I have bought a few used ones from there, search "2013 Polaris RZR800 ATV regulator". You need to be sure it is OEM, be sure you can see the ID number in the seller photos.

Here is one I bought :



It was dirty (ATV) but it cleaned up OK and works excellent.

You can also buy the wire harness kits from Ebay (Chinese stuff OK) search "voltage rectifier connector for street Triple 675 675r 1050R T2500676"



Use thick ground (black) and power wires (red w 30A inline fuse), hook up directly to battery. Other side goes to generator plug.
