Thanks, LIMagna.  Good to know where to find these units -- and at a rational price...

No problem Lawrence.  If it wasn't for the info I found here on these forums, I would not have known to look for the OE equivalent part.  BTW, here's the direct link to the Shindengen part for anyone looking ... they seem to have several aftermarket parts on their site that work:

I bought this bike with a bad R/R and it was over-charging and boiling the battery. That's one of the reasons I got a good deal on it, I don't think the PO had any idea what was wrong with it. I replaced the R/R with a OEM Honda part, replaced the battery and haven't had any further problems with the charging system yet.

That is great that you fixed it. 

Not my first bike but the first bike I bought for myself I got real cheap because he could not keep it running.  I replace the main jet and it ran like a bat out of hell after that.

My RR went out the second time in about 2 years. During the hot part of the summer. I have read little ways through the Thread. I am not quite sure what is going on.

Problem Battery boiling and a lovely Sulfur smell. Yay!

Any ideas what to do besides change the RR and Battery Again?

I guess you would say MY RR WANTS to show how powerful it can be not how it can die.

This time no fuses pooped so I guess that is good.

Kyle, there are two failure modes on these units.  It is called a regulator/rectifier, because (duhh) it has both functions.  If the rectifier function fails, it just doesn't charge and the battery runs down.  If, however, the regulator function fails, it continues to charge, but for all it is worth -- cooking the battery.  This appears to be the failure you have suffered.

It seems that you have no choice but to replace the regulator/rectifier and the battery.

Get the relocation kit or some other device to cool your regulator to eliminate this from happening again.

I was noticing the relocation of the RR on a couple of bikes. Is it a kit? and where do you get it? Or can I do it myself?

Here's an interesting thought from the Magna Riders Forum, that suggests that a bad battery can cause the R/R to fail.  Any thoughts??

Hey Guys,

Long time no post, I never followed up with my R/R failure
http://www.magnaownersoftexas.com/forums/index.php?topic=2622.msg34495#msg34495

After buying a used R/R from a salvage lot off of a another Honda a 250 something i think, the used R/R had the same wiring as the Magna one anyways.

I decided to relocate it to a more ventilated position, I ended up extending the wires on the R/R by cutting the wires off of the burntout R/R and using them to extend the ones on the used R/R.

I ended up relocating the R/R to in between the rear wheel and the exhaust using the upper exhaust mounting bolt. That was back in July of 2009 and no problems since.


I'll post pics when I get home from work today. Ok so it wasn't the day I said I would post them but here they are.

Before anyone says anything I know... I forgot the Seafoam.

A fellow MOOT'ster has designed and built a custom bracket for putting the RR in that location.  It has so far worked great!

Regulator failed today after about 4 years with a used R/R, so moving it seemed to dramatically improve its lifespan.

Regulator O/C failure

78,000 km (only 16k km since the last one) but I only ride in the hot summer months

I'm looking into possible buy a better after-market higher current output R/R for the magna.

My 3rd regulator has failed... One leg blown (undercharging)
Aftermarket, probably has at least 60K on it and 5 years old...
Buying a ElectroSport via Amazon for about $75 shipped...

Arrived today... Did not know that it was made in China  :-(
Couldn't they put a little longer wires on it, really... How much would it cost?
It would be fine for the stock position, but I have mine on the side...

I'm new to the forum and first time Magna owner and love it.  Have a 1996 Honda Magna Pure Red.  When I got the bike I noticed the R/R wires (yellow side) where burnt in half.  I replaced the R/R and kept popping my 30a main fuse.  After a couple hours of frustration and metering all the connections on the bike I couldn't find the problem.  Then it hit me and I checked the main wiring on the new R/R and found they miss pinned the hots and grounds.  After repining the harness she took the fuse and its been happy trails since.  So all you out there going to change it out and have the same problem maybe this will keep you from those hours of frustration lol.  Funny story had to share.
