Where did you get your regulator?

Where did you get your new regulator?

I believe my regulator is going out so I will be replacing it.
Some of the after market ones have longer wires / leads that are more friendly to the relocation modification. 

I know some have not had good luck with after market ones so which ones are those.

Robert,

  I got mine here:

http://www.regulatorrectifier.com/catalog/1997-2000-Honda-VF750C2-VF-750C2-Magna-Deluxe-Regulator-Rectifie

  It's the OEM Shindengen (part # SH538D-13).  Wires are exactly the same length as stock since it is the stock part.  Price is much better than going through Honda.

Funny I got mine from regulatorrectifier as well, but my leads were longer...

[LIMagna]

They have several regulators that will fit the Magna ... the Shindengen is one of them:

Perhaps you purchased one of the others?

Prehaps.. The one I ordered said it produced 10-20% more power than stock.. (IF memory serves me correctly). All I know is, it's been working fine and the extra long leads helped me move my regulator to the side of the bike.

I ordered the one Hootmon recommended mainly for the longer wires for the relocation kit.

I see the one on Hootmon's bike is black so hopefully it will be black also. I did not see a color selection so if it is gold that will be OK.  


Greg said he should get the bracket in the mail on Monday. So hopefully I will get them both by this weekend.  

I enjoy riding Brenda's bike but miss my Magna.

I've purchased from Electrosport Industries twice now (one for the GS850, another for the LS650 I just got) and have been very happy with them.

Got the regulator today.  It is more of a dark chocolate than black.  Hopeful will get the bracket by this weekend.  Greg – nudge nudge pock pock. 

The regulator gets hot but probably not hot enough to require high temperature paint.  I wonder if I could paint it a high gloss black paint.

I would not repaint it at all.  When the bike is still, radiation (primarily infra-red) is, I believe, a significant portion of the heat dissipation mechanism.  Unless the paint is designed to radiate, it may not do well at all.    I suspect the coating on the device is anodized to the aluminum, and (hopefully) is chosen to maximize the radiation effects.  While the appearance of a surface may have some correlation to the radiating capability, appearances can be deceiving, as our eyes do not perceive infra-red.   Having said that, I think that, gloss will, in general, not radiate as well as flat.

If you choose to paint it, I would advise a very thin coat.

I'm with Lawrence and I would go flat for reasons stated and aesthetics.

Yeah, what Lawrence said.. But in Yellow!!!!

[punchy]

the regulator that i bought was made in...................no not Japan................not even from a crap company in China, with little or no quality parts or quality control ..but ..............made here, in England,
which makes a change..i;ve found that anything......anything....that needs to be used, to be relied
on which has marked  "  Made In China" on it is rubbish quality...the Chinese are copying everything....punchy..

Won't black also absorb radiant heat from the sun during the day? Heat + voltage regulator = bad news

Radiation efficiency is indeed bi-directional, so yes, direct sunlight adds heat to an efficient radiator.  Charles asked this question during our discussion of relocation strategies, and, according to my measurements, when the bike is parked, at idle, for a several minutes with the sun bearing directly on the regulator/rectifier, the temperature reaches approximately the same maximum that one under the battery box reaches while riding.  In order to find these conditions, however, I had to wait until late in the day, and park the bike with its axis orthogonal to the sun's rays, to achieve normal incidence on the R/R.  Other incidence angles do not show as much temperature rise.

So what does this have to do with reliability?  That depends on the failure mechanism.  If you believe that the failures are induced gradually, which seems to be the assumption on this thread, then some positive function of both time and temperature is what drives failure rate.  Under this assumption, you are clearly ahead to relocate the regulator/rectifier.  If, however, you believe that the failure is due to a single temperature spike, then relocation is of limited value.  I personally have no data to support either theory, but lean to the extended thermal stress assumption.

By the way, Dave, removing the potting material from the failed R/R you provided me proved too daunting.  I eventually gave up and proceeded to drill it out, destroying all evidence in the process.  After hours of drilling, chiseling, cursing, etc., I have still not removed all the stuff from the heat sink/case.

I am thinking I will leave it alone at least for now.
