1981 kz1100 a1 not charging

I hace a newish (about a year old) rotor, just bought brand new stator, and reg/rec. I'm getting 48-50vts off the stator at 4000rpm off yellows at the male side of the stator 6 prong clip. I'm getting 48-50vts off yellows at the male side of 6 prong clip going into reg/rec at 4000rpm. I'm getting only 10vts at battery at 4000rpm. I have continuity between the reg/rec and positive lead at battery (battery disconnected of course) and continuity between reg/rec and the neg lead at battery. What the hell am I missing?!? Any and all help/advise on the matter is GREATLY appreciated as I am at wits end.

Even if new, it sounds like a bad regulator anyhow.
Have a spare or can someone lend you one to eliminate that?

The following may help you...

1) disconnect the stator wires from the harness and set your multimeter to AC voltage. Start the bike and rev the engine to 5000 rpm while probing between the three output legs of the stator. You should be getting about 75+ volts AC on each combination of legs. For example: from A to B, A to C, and B to C.

2) assuming the above checks out, wire the stator directly into the R/R. Bypass the factory harness. Connect the R/R ground to the - battery terminal and the + to the positive battery terminal. Next, start the bike and rev to 5000 rpm while putting your voltmeter across the two battery terminals (set meter to DC voltage of course). With any luck you should see about 14.5 volts.

If you get the voltage you need then consider adding a fuse in line with the power output from the R/R to the battery. The R/R ground can go straight to the battery without concern.

Thanks guys. I'll try to hard wire the r/r as suggested and see what happens.

A bit of a follow up, before I hardwire the thing, I isolated the white and red wire coming from the r/r at the junction where it spits off to the starter solinoid and the 30amp fuse and it's reading 150vts! So I'm guessin that the new r/r is just as bad as the old one. That's what I get for being cheap and getting the $25 r/r, time to spring for the $100 one.... any recommendations? Z1enterprises are out of stock.
