ok folks..please help..we own a 82-xs650...it fails to charge correctly..the stator unit was replaced once before and it made 14.1 volts when running...now..we replaced the reg/rect unit with a brand new one..the bike still after having a brand new battery and brushes installed to chargeing system fails to charge correct...we went to ride the bike..the battery was dead..we replaced it, then the reg/rect was replaced..still no help..then the battery..still no charge, brushes..new...nothing...now we replaced the entire charging assembly with a used one it charges fine for a couple thousand miles...now it appears to have died again...anyone know where to look for starters and anyone know how to ''properly '' test the windings? our book says but it really dont tell ya what ya need to know in detail...someone has to know these chaging systems very well..they been around way to long..please feel free to contact me..we need technical help here..thanks !

My stators read .7 ohms between all the white wires and the rotor should read 5 ohms or better between the rings.......good idea to stand off the round case a bit so it stays a lot cooler in there.......water hurts nothing ....constant dirt roads and sand might.........mines been open 60 thousand....
Got the bike at 10 thou.....the PO had just replaced the rotor....th stuff in there can last if kept cool...........discounting a short somewhere....

We need some key information. What is the voltage across the battery at 1200 RPM (wait a few minutes after starting to measure)? What is the battery voltage at 3000 RPM?
It would also be helpful to know the voltage between the 2 brushes on the alternator, again measured at 1200 and at 3000 RPM.

ok...heres my question...to measure across the 2- brushes...put the neg side of the meter on a good frame ground the the hot on a brush end...or measure directly across the 2- brushes? not really a idiot here..just dont know the proper means of testing. also....if i take a tester and measure resistance across the white leads they should all read equal..correct? ...next question...do the brushes send in electricity or send it out? basically i need this..nobody has ever told me just how this type system actually functions..if i had the basic's as to how it works i'd feel much better in trying to repair it..my test equipment is basically a ohms meter along with another unit that measures ac/dc voltage ect....electricians type meter.

ok...heres the deal...today i done a check at 1200 & 3,000 rpm off the top of the battery...it reads like this showed 12.09volts @ 1200 ...then at 3,000 rpm it showed 14.20 volts........... now at the brushes ..with the motor off the right side brush showed 11.28 volts ..the left side brush only showed about 1-volt..ok, for the feeler gauge magnet test..if you turn the key on it pulls the feller to the end of the crank ok, shows magnitism, then if you put it to the right side brush it shows good magnetism...for the left side brush, very little magnetism...ok, does this help anyone decifer whats up here? all help is greatly appreciated.

Well, if you are getting 14.2 @3,000 RPM then there is nothing wrong with your charging system.

Possibly you have something shorting to ground killing the battery when it sits. I suppose on an 82 you have multiple fuses in the fuse box. You could put a meter on the fused circuits to determine if one of the circuits is drawing voltage while it is shut off (draining the battery). If you can isolate in that way you could trace and inspect the wires , connections etc for a short to ground.
You could also pull all the fuses and see if it still drains the battery.
