Alright, firstly i tried using the search and reading through the forums before deciding to post here, but i am completely at a loss.
Essentially I am not getting a charge (or atleast an adequate charge) to the battery. At 1000rpm it's about 11.3v, at 3500-4000 it's 11.89 max (after adjusting the regulator).
I'll just lay out what i've done or checked thus far and see if you all can give me a clue:
About the bike:
1977 XS650, new to me, runs great (if not a little rich) other than the charging issue which kills it after the battery is drained. Oil cooler installed. original everything else as far as i can tell. Headlight will not come on (i've suspected this may be related, possible short?). Rear brake light works, no running light (not sure if it's supposed to have one).
Tinkering:
I have three rectifiers available to me; the original stock one, a radioshack bridge one i built, and one from my cb750 (82). All three read the same DC voltage output of 11.89.
I have two regulators, the one that came with the bike and a used one i picked up at a shop.
Two available batteries, brand new. One AGM, one regular.
I've tested the white wire to white wire coming from the stator, I get 30-35Vac across any combination (this seemed high to me).
Brand new brushes, three available sets. (Original owner kind of unloaded his garage on me in this deal)
It's hard to get my multimeter's probe to the inner slip ring on the rotor (with brushes removed) but i get a reading of 1-3ohms across the inner and outer. I know you're supposed to get 5-7, but i wouldn't think i'd be getting the AC out if the rotor or stator was the culprit.
Two available headlights, the original, and my cb750's i used to test with.
My turn signals on one side come on but don't blink, and on the other don't come on at all, so i imagine the flasher relay is bad too. (again, possible short eating my DC voltage?)
...
I think that about covers it, I really don't want to dip into out of pocket cost on a stator or rotor just to find out they weren't the problems, so any ideas would be greatly appreciated. Thanks guys!
