Have you sandpaper the frame to get metal-to-metal contact to the R/R? This will transfer the killing heat from the R/R. Also check that the R/R is grounded properly.
Is the battery in a good condition? What is the charging voltage @5000 rpm?
3.5 ohm instead of 2.5 ohm could be a measurement error. Check that the instrument reads zero ohms when the test leads are connected to each other, and also check that the batteries are OK in the instrument.

Are you getting 40 -55 volts from the stator on all yellow leads? If thats good and the rec is good and grounded/earthed properly, then check the battery. I know you've replaced it recently, but even new batteries can be NFG. Everything seems to check out fine according to your findings. I've seen many cases of loose connections and grounds. Not just at the reg/rec and battery, but other ground staps that become loose over time around the frame that result back to charging issues.

Check out this VFR article. The charging system is closly that of the CBR's. Mind you the guys kinda get into a heated argument, but there is lots of good information that may help you out with your chrging problem. Good luck!

Thanks guys for the help and suggestions - I'll check it out and report back on what I find.

Shadow, you know I have little mechanical savvy, so the best advice I can give you is to open a shop selling R&Rs... ! At least you will get discount.
There must be an underlying fault, eh? You cannot have to replace the items that often without there being something else causing it. (You will know I have no idea what that is of course  ).
Good luck Pete.

Well, we've made a start on tracing the reg/rec problems.
First, we checked continuity of the 3 yellow wires, from the stator plug to the reg/rec plug, all fine, and resistance the same on all 3. I then decided to strip one of my burnt out rectifiers, and found that one of the yellow(field coil connections had burnt out under the rubber cover. My son, who has almost completed his elecrical engineering diploma, pointed out that this may be the result of some problem with the red live wire, between the reg/rec and the battery. Resistance was about 40% higher in the red wire than on the yellow wires. We then started the bike, and checked the resistance in the red wire, 57,6Ohms at fast idle, climbing as the revs rose to 65.7 ohms at 2000 revs!!!! (No connection to the stator, just the battery )
WE MAY HAVE FOUND THE PROBLEM My son says it sounds like a partially damaged red wire from too much heat, or a short, which would cause the reg/rec to sense it should pump more and more current to the battery, until it failed............
I'll continue first thing tomorrow, stripping the wiring loom, and keep you informed.
The light at the end of my tunnel might not be an oncoming train.... I hope.......

Good news Pete, I suppose that is the good thing about being your age - you have a son old enough to use the brains his mother gave him  .
Keep us posted; it will be a lesson for us all.

Thanks Flogger, you're too kind...
Going to change your name to "The Clockwork Orange"- let's see if you understand the significance of that......
Also, check your personal mails......

We have now checked the current from the stator - within spec.on all 3 wires
No earthing issues
No line loss, wiring within specs. Replaced one connector, which looked OK but was slightly burnt.
Replaced reg rec.
Charging within specs, but r/r getting warm quite quickly.....?
Checked battery water.
ALL WE CAN DO NOW IS WATCH THE VOLTMETER, AND HOPE....again.....

New reg rec figures for the Electrex R/R as follows
Max charge 15 Volts above 3000RPM, running voltage constant at 14.7 volts for 100 miles. Speeds from 0-125MPH, average around 85 MPH.
5 Minutes after I stop, reg/rec is quite cool.
I still think the voltage into the battery is too high....
What value of resistor should I fit into the red power line between the r/r and the battery to bring the input voltage down to, say 13.5 volts ? Help please, and a pic of what it should look like...
I think the battery can't handle the high voltage and ambient temperatures, and it's causing the battery to lose water, and when it gets too low, it cooks the regulator..... I'll be checking water loss after today's ride, and making a "dip stick" so I can check water levels without removing the battery every time....THE NEW VOLT/TEMP/TIME GAUGE IS A PLEASURE !!!
Now we wait and see......
Thanks to you all for help & suggestions.
