Very different Mr A.

The best reg/recs are Mosfet. Jaws now sells the mosfet type. The cheap reg/recs dump the unused power into a shunt hence the excess heat. Mosfets control the output from the alternator so little excess is generated.
If you are going to replace the RR I would buy from Jaws. A cheaper one would not be a good idea as Andybird would say. Correctly!:-0)

I don't think it was the carwash. Plugs are not ideal ways of passing on high current and heat will always be created which abets corrosion and so the circle goes on. There is always some resistance across any joint which is why gold plating is used as it has excellent conductivity and resistance to corrosion. Not having much gold is why I have soldered everything and taken the output from the RR directly across the battery.8rfl@

Sorry Andy but some of us live in the real world where expense IS an issue. ?200 may be easy for you but some of us have to compromise. Replacing the three would be ideal or why not replace the bike!:-0)

Bit touchy??

I too live in the real world, one where a failing reg rec will have more than possibly fried the generator as it goes into warp drive, quite possibly taking the battery out as well.

Or maybe not.

BUT how many threads on here where one part has been replaced and others follow, sometimes meaning the 'new part' has to be replaced again.

Replacing all 3 is the only 'guaranteed' way of sorting the charging problems. In this case if they are original from an early Bird then I would suggest 'preventative maintenance' is appropriate.

Just my thoughts based on my personal experience, albeit not as an auto electrician.

Didn't mean to be "touchy" Andy.

Even replacing all three is no guarantee Andy as wires corrode....as in "loomfix".
Providing the remaining bits are properly checked then I don't see any reason to replace all three. I am waiting to see what voltages Mr A gets when he tries it out. If the voltages are good and connections clean then he should be ok. Mosfets are MUCH better than shunt Reg/recs as they don't have the heat problem which imho is the root cause of most (not all) charging problems. I've seen peeps with computer fans fitted to try and cool their RRs. Mosfet is the expensive but best solution.@tu*

I have ordered a new plug and connectors as the original isn't worth messing around with for the sake of three quid. Also given the impending Ireland trip I think I will take the plunge and buy a new reg/rec from Jaws.

are you saying that all those with shunt type reg/recs should immediately switch to mosfets because they are better?brok3

re read Andy's post Bill, I suspect he was having a chuckle at your (unintended?) play on words.....
It'll be better than your current one Mr A

or maybe he wasnt! :dunno:

ps Bill, why is there a little 'X' in a little cloud under your stats top right of all your posts?

I suspect not 4_4_2. I rather think he was trying to point out that he had recommended replacement.:-0)

Er, no, it was the 'unintended play on words' i'm afraid. I am far too classy to point out the other thing.;-0))

:eek: Did Bill OR Andrew not mention that?? :dunno:

Nobody asked. If anyone had asked if anyone had a spare plug/connector I would have been to the post box as well to post it out free (as ever). But nobody did.8rfl@

Thanks for that, I think I will replace the plug and connectors. Does anyone know where I could buy a new plug similar to oe part?

Correct! I asked where I could buy one.c7u8

Update

I have replaced the plug and connectors and fitted the new reg/rec from Jaws and the voltage across the battery is reading between 13 to 15 v. The meter moves between those readings and doesn't give a steady reading. I ran the bike for a few minutes with lights and indicators on and noticed the casing of the new regulator quite hot, not so hot as not to touch but definitely hot at the top edge. Should I be worried?
