    Called into Electrex yesterday (they are just up the road from me) to get them to test my VFR800 FiX reg/rec (updated OEM) which was misbehaving. It had done about 20K and was not giving full output on one phase. The technician just mentioned their new version was a MOSFET design and would be a very reliable replacement. Having read about the Shindengen FH012AA MOSFET regulator which everyone seems to recommend, I thought it strange that no one had mentioned any alternative MOSFET designs. Needless to say I bought it! It runs very cool, stable 14.5V output at all revs and smaller/lighter than original. Very pleased! ElectrexReg.jpg

    The only Electrex I could find that has bike parts is in the UK. Where are you located?

    Sorry, forgot to mention location. I'm in Reading, UK west of London. Electrex are in a small village industrial estate just north of me. They are Electrex World and have a good website. They do a lot of aftermarket specialist electrics, particularly classic bike 'upgrades'. They also have one of the best 'sorting charging problems' advice sheets I've seen: http://www.electrexworld.co.uk/pdfs/Troubleshooting-3P-PMG-&-RR.pdf. Had similar problems with my 1986 VFR FG. I think their FiX reg/rec will fit that too. Their model code for the FiX reg/rec is RR53. It was a bit on the pricey side but if it sorts the problem long term I'll be very happy! Best wishes and good luck with all your problems! Tom

    That explains it. I thought my questionable ability to use Google effectively was worse than normal. :smile: Glad you're happy with the R/R. If I ever need to replace one, MOSFET is the way to go. More and more bikes are using Shindengens as original equipment, although the Shindengen website now only lists the FH012 (they used to have an FH008 and FH010, which were lower amperage units).

    Hi tomwalter and anyone else,
    Wondering what the old original looks like. I think mine has been replaced as it is silver and has markings SH579C-12 with a circle that has >II< in the centre but the arrows are filled in.

    Cheers Lgn001 the link was great. It states the number I needed to tell me it is original but the more reliable version. Thanks again.

    No problem. I do what I can to make up for the times that I just confuse the issue (as in I'm completely wrong!). :biggrin:

    U.S. based riders can look to Rick's Motorsports Electrics for a MOSFET reg/rect. They are even distributed through Tucker Rocky, but many dealers don't know to check for the "H" designation parts. If my memory serves, Rick's part number is 10-126H for the 5th Gen. The only time I have seen one of these fail, it involved the stator pulsing/surging as well, so not sure the r/r was really to blame, but it started dropping voltage when hot...

    Apparently there are two different types of MosFet voltage circuits that work with our bikes. The Shindengen FH012 uses a parallel design . Excess power is released as heat. They are very low leakage and can be connected to the battery without fear of discharge. Mine only gets warm.

    There is another type of mosfet design that is in series with the alternator. Only just enough power gets past it. Of course the voltage in the AC circuit gets very high.

    I am under the impression that many regulators fail because they are getting electrical noise from the ignition system and start lowering the regulated voltage causing excess current to be run though the unit and over heating it.

    A fairly good check (after voltage checks of the input and output) of a rr is to try touching it after running the bike for a while. If it is too hot to touch you will be in trouble sooner or later, solid state electronics don't like heat.

    I know that you guys are talking about the r/r. If in the US and needing an upgraded shindengen r/r I have a brand new one in the box that just got delivered. I ordered it a week previous to my bike getting stolen. Let me know and I am willing to make a deal on it.
