I’ll wait for the diagram, that was my original attempt.

I’ve tested a some different combos to the field coil plug, but green-green white-brown Black-black. The green/brown of the coil should technically be all I need to use based on the wiring diagram. Should I hook up the loose green from the R/R direct to ground, that better be the solution to...

.7-.8ohms both ways between all whites, no continuity anywhere to ground. Have tried red and green from the rectifier side direct to battery, still minimal AC voltage. Maybe .5VAC while running out the stator between whites disconnected from rectifier. A 40 year old bike circuit can’t be...

All tests were open except from Green-Brown Brown-Green 3.8 ohms.

My green wire with a male spade not in the plug has continuity direct to chassis. I believe my rectifier green ground may be separate, will run it direct to battery. Do you have this R/R wiring diagram?

Still no white wire AC or battery DC increase voltage, tried swapping the 3 wires to the field coil around no change. Coil must be trash.

Coworker introduced me to Logic, I’m pretty sheltered in hip hop but it flows well.

Fire and verify tomorrow. Oh, how much amperage will that rectifier pull? I can’t trace the power back as it’s blind in wrap so I added a blade fuse to be certain. Probably goes to the starter, but if there is any residual draw just pull the power.

Good, because I did check continuity and the case was not grounded anywhere. I am confident your advise will have me charging granted something is not haywire in the windings.

R/R came yesterday, thanks again. When I wire up tonight, the Red and green from the Rectifier both go where? Switched 12V or can I go direct to the battery? Also, the regulator 3 wires are white/black/?green to my field coil black bottom and green/brown top of the plug/receptacle. I'll read...

Interesting information, just curious how you know the replacement R/R(stated for 78-79 xs750) is not correct? The permanent mag uses all 3 wires? Here is my alternator assembly. Are there no other ways to power the eMag, I might wire up the old r/r to see if I can get magnetism if the...

(3) A/C whites are going to (3) yellow in the eBay rectifier with (1) extra yellow to headlight relay, red from rectifier direct to battery, green from rectifier to key switch 12v Magnetized(hopefully) field coil BLACK to red through eBAy regulator, green from field coil to green through...

See I don’t know if I have the eBay rectifier side wired correctly either. If I power the red wire(on white/yellow side) direct to battery, green(currently disconnected in photo) goes 12VDC but not the other way. Also do not know if polarity matters on regulator side green/red male...

There is a black wire to the stator as well, does that need a chassis ground or is the R/R case sufficient? Since I’ll be doing some trial and error I wonder if a 9V would have enough juice.

Going to need a little trickle charge and kickstart, I believe I can test the case for magnetism with the key on.

Doing a little more research says to test the field coil wiring as it may power the magnetic field. The previous bike owner(s) had been in the R/R harness wiring and removed a receptacle to the regulator side and my eBay replacement R/R may not have the same color coding. Guess and check...

Own a ‘79 SE Special that I’m getting ready to sell. It’s never charged properly from my initial resto, just trickle charged and never went on long trips. I presumed it was the R/R which was actually confirmed bad through continuity. However, continuity through 4 whites coming off the stator...

Thanks for looking into that, so they actually measure as advertised? Only reason I ask is 3 years ago I put a set on a cb450 that were supposed to be 12” but were actually 12.5 c-c at the lowest.

Sits too much now, time to sell.

Looking at putting a set of those rear shocks on my xs750, what center to center did you order and actual measurement? Need 310mm give or take a dime to keep angles decent with the front drop. Wheels turned out , love me some gold accents And two-stroke smoke
