Ok guys here is one for you. 2007 Road King custom. 48k miles. Bought it the end of April it had 40k miles then. I just received two new CE rectifiers today. Installed the first one. Fired up my sled. 12.5 vdc. Ok so I go check all the connections. Fire it up again 12.5vdc.
I unplug my stator do the checks continuity between phases and nothing to ground. I start the bike and at 2k rpm I am getting 50vac.
Now I figure has to be bad connections checked them again and they are all good atleast sure seem to be. Start her up again 12.45 vdc. Now I check all my fuses and any other connections I find nothing. Everything checks good.
So at this point I am baffled.
I am hesitant about trying the second rectifier. I had to wait a week to get these.in am I missing something that is right in front of my face? I am not a newbie when it comes to sleds and I am an electronics controls tech for 15 years so I understand what I am looking at. I am going back to look for a connector on the bottom of the frame that has been pulled apart or anything. I am waiting on my service manual to arrive it was ordered last week so I am kind of blind to some things.

Any thing anyone can throw my way that may be the least bit helpful I would appreciate.
Thanks

 

Can you hook a scope and check for presence of all phases?
What's the battery voltage?
How many Amps is the rectifier passing when you get 12.5V?

 

how many rpms is the motor turning when you get readings of 12.5 VDC?

above 2000 ?


is battery good ?- a duff or discharged battery will put a load on the charging system.


terminology:

you have a "regulator"- it does have a rectifier component ( converting AC to DC voltage), but most will better understand the term regulator
