honda motorcycle rectifier

Anyone have a detailed test, using a voltmeter to test which is possibly bad? My bike isn't charging, and it's either the stator or rectifier, and neither is that cheap. I have searched and found a couple of post giving basic info, but nothing detailed. It's that or I take the bike in and pay $90 for diagnostics so they can order just the bad part.

Do you have the shop manual?

I've never done troubleshooting for those parts, but it has a pretty good electrical problem/test section.

No, but I think I know where I can borrow one.
Thanks.

Don't need one....follow the guide in the link in my prior post.

I just went to that. Awesome. I even have a meter with all the bells and whistles so I can follow this through. I'll see if it jives with my bike.
Thanks,

I got a manual if you need it. Also, worse case, come steal the rectifier off my bike and put it on yours.

Thanks G. Worse case, I'll just borrow the manual. I wouldn't want to risk ruining your rectifier if that's the case. I have a history with electronics. My brother and I both had nice stereos in our trucks when we were younger. We both had electronic crossovers. Well, my brother's crossover went south, and he asked if he could borrow mine as he was going out that night. Well, unbeknownst to me, he had a short which blew his crossover. Did he fix the short before plugging in mine? Of course not. My crossover lasted a full 2 seconds before "electing a pope". (White smoke for the humor impaired). I do appreciate the offer though, and will reciprocate anytime you need something. I think if I can't figure it out this wekeend, I am just going to run it to Kolbe next week. Their prices are amazingly identical to Ron Ayers, and I trust their work.
Thanks,
Fig

That sounds more like your brother has a history with electronics.

Tombs incomplete charging 101:

I would check each lead wire coming from each coil winding for ac current. If you have a broken coil it will test as an open when you hit both the inbound and outbound wires. I am thinking if you have a bad rectifyer you will have ac current on the wires to it and no dc current from it.

If the charnging system is like that of a car you will have a diode trio with a feedback system coming from a regulator. The regulator senses the dc current availability and can raise or lower the output from the diode trio (charging coils). The plain old systems just use a rectifyer or zener diode to dump excess power into heat with no control over rate of charging.

Good Trouble tree. I have a manual. Haven't looked at htat section to see what they have for trouble shooting this kinda problem.Made a copy of this & will keep it in there. Haven't had any trouble W/my RR but then again it's only 1yr old W/1400 mi. since new. Great find!
