HHB PMA not charging above idle?

[SOMMS]

Hey gang,

Long story short: xs650 hardtail with Hugh Handbuilt PMA, Sparxx Capacitor, no battery just kick.


Yesterday after a nice 30 minute ride I pulled over to the store. Shut the bike off. Went in got a soda. Come back out...the bike wont kick over. I try for about 20 min before trailoring the bike home.

Bike runs great with a battery. However, this is what I'm seeing...

Off the HHB stator wires I see 12.50, 11.5 and 11 volts AC at idle. I see 20, 20 and 22 volts AC when I'm revving the motor.


Now get this - off the regulator I see 12.5-13.5 volts DC at idle...but when I rev the bike it DROPS to 4-6 volts. ???


Any ideas gang? Does this mean a bad regulator? A bad stator (I already had one of those and replaced it) or something else?


Thanks a bunch for any insight you guys may have.


PS- I have sent Hugh an email but I know how busy he gets and it may be awhile before I hear back.

On a p.m.a alternator I would expect to see around 14.5 volts at 2000 rpm.

From the figures you have given that is probably OK.

Sounds like the r/r is Donald Ducked but rather than guess suggest you work through this or if that checks out OK this

I had a similar prob and replaced the regulator to fix it.

Yes, its seems like your regulator has failed. If its under warranty, you should get a new regulator for no charge. Did you buy the second stator from the same aftermarket seller? When you replaced the stator, was that under warranty?

How many months/years have the stator and regulator been operating before they fail? This does not speak well for the quality of parts you are buying.

Retired - I did get the 2nd stator from the same place - Hugh himself replaced it at no extra charge. Maybe when the first stator went bad - it damaged the regulator...and it hung on as long as it could til it died on my yesterday? I dunno - just a theory.


Problem is - I need the regulator by mid-week as we are going on a ride. I hope Hugh get's back soon.


Thanks for the feedback.

Jamesgs4 - cool! Replacing the Reg/Rect did the trick?

 

[jamesgs4]

Email me today - we have regulators in stock, but I haven't updated the website yet. We can send out a new regulator/stator/etc as you need. Thanks man!
