Regulator / Rectifier CBR1000F (Honda/UK Electrex RR23 or Ebay China))
 

Regulator / Rectifier CBR1000F Options (Honda/UK Electrex RR23 or Ebay China)
I've a 1990 CBR1000F model - In 21 years I've blown the following R/Rs

• 2 x Honda R/R [$220 approx]
• 1 x Electrex RR23 (lasted 4 years) [ $160 approx ]

Now going to try one of these from Ebay China - just because it's only $50 approx.

Anyone else tried one or will I be the first to write the test report?

Looks like you will be the Guinea Pig.

Let us know.

Basically, a rectifier changes AC to DC, and a regulator bleeds off excess current as heat. My old GS1000 had a separate regulator and rectifier, which was a great idea, but it took up too much real estate. I have a single R/R by Electrex on there now. Any R/R can work if the wiring is correct.

My friend's VFR has a small computer fan on the cooling fins of his R/R. Since the R/R on our CBR's have no cooling fins, could an air scoop or fan be installed?

Hi Slowpoke,

Hec, at that price buy 2. Then you wont be stranded when the first one dies.

Then you wont be stranded again when the first one dies. :)
I don't know about those Chinese models, Martin.
OK around town but I'd never trust one on a long run without a "proper" one as backup.
And I'm not talking about an original Honda one as backup either....

You'd probably have to call Johnno again and the wine bill could be excessive :eek: :)

Personally I think the key to RR longevity is keeping a good battery
in the bike as a battery that's just about had it can take a good RR
down the drain with it.

3 seasons and I toss my battery for a spanking new one

Hi Shadow and Sprock

Sprock - I fully agree with your logic about having a properly maintained battery in good order.

Now .. I don't know what it is with these early Honda electrics - Some guys seem to get a lot of trouble and others seem to get by without even having to know what an RR or a stator is.

FYI in my case -

• Bike standard - no electrical add-on.
• new AMG battery 14 mths old.
• New RR - Electrex RR23 (UK) - 4 years old
• Bike on intelligent tender when not being ridden.

I have checked all voltages / resistances / currents and they meet specifications.

Guys - the frustrating thing is the RRs don't seem to last for me.
From my experience

• the Honda ones both failed on the Rectifier side (No, or low, Charge to battery) [No collateral damage and suspect battery of poor condition initiated this as I had no battery tender in those days]

• the Electrex one failed on the Regulator side (Battery overcharge voltage ((more than 15.5v)) and this then caused the collateral damage of cooking of the good battery and then the Ignition Control Module (CDI) unit).

Sorry, having done all my checks I don't have any answers to this for benefit of others.

Will let you all know on the Chinese RR - I don't expect it to be a panacea - just maybe a copy of the Electrex one at half the price.

Hey:

NAGA, just to let you know I tried one of these that had the same pic but a different company and it did not have the correct amount of connectors, so could not be used.
So please check it out before wasting your money.
