I couldn't find this question asked previously so I figured I would post it up for my benefit and for others too.
I have freshly built 701 SN with a new cdi. When I had it running a month ago, the battery was not charging. I tested the lighting coil green leads, perfect @ 1.3ohms.
I pulled off the rectifier and the numbers didn't match the repair guide chart as closed as I would have liked. I tested another rectifier I had laying around, same results. I bought one online (from a source that "said" it was working). Same EXACT numbers.
So I put the new rectifier in. I tested connected it all up except for one green wire, which I put to the positive lead (on the lighting coil side) on my multimeter on AC. It came out around 2.6 ac when I cranked it. I don't know what it's supposed to be, but it seemed strong so that told me my stator was okay.
So I plugged it back in and disconnected the RED lead coming out of the rectifier and measured that against ground while cranking. I was getting 3.6V steady. I have a stupid Pro-tec pipe that once installed, means I cannot get my ebox out again without removing my exhaust manifold so I want to make sure this is working before I put it all together. Obviously the draw from the starter will not let me get a good reading at the battery terminals while cranking, it has to be running on it's own.
So would you think 3.6v DC coming from the red (disconnected) rectifier lead is normal? There is a VERY good possibility I missed a ground or something when I first noticed it not charging and has since been fixed when I reassembled it.
