    Hi,
    Got the bike home - Stator dont show any issues - So glad I didnt go for what the shop suggested spending $750 replacing good parts.
    Further checks seem to point to a bad regulator/rectifier though, and even though it looks similar to your pic there are some difference when it comes to the coding...
    Mine says: SH572E-12 (with T9.8) just below - thats it - no part number or identification other than that.
    It is a single 5 pin plug though - I've seen the SH572E-12 listed on fleabay but they either have two plugs and/or a different number written below i.e mine have: T9.8
    No idea what that means or if its important

    suggestions...?

    cheers

    That second row of number's is the batch number and build date code's etc

    Do you want a brand new one or a used one, genuine, aftermarket, local or oversea's?
    It'll be dearer locally

    Aftermarket ex China, $16.20 inc post (4-6 week's wait)
    https://www.ebay.com.au/itm/Motorcy...296679?hash=item2839602f27:g:QsUAAOSwNRdX30Mb

    Forsetti (made in china) $89ono inc delivery ex Qld, (around a week postage), better quality than cheap china

    Wanting to throw the most expensive parts at the bike was a bit of a red flag

    Something interesting I learned last night - Forsetti is owned by Yamaha Australia

    Find someone wrecking a modern triumph or bmw bike and get the reg/rec and weatherpack connector off it - they are commonly shindengen fh020aa (mosfet) with 5 pins on 2 separate plugs - one has three for your stator and the other one for the 12v and ground

    The wiring is dead simple - 2 or 3 phases from your stator going in (in any order) and 12v output/ground to the battery if you wire it directly in and bypass the bikes wiring loom, if you suspect a break or short in the loom. You will need a fuse or auto reset circuit breaker.

    Guy named Mark Boxer - he runs Hoon TV - just got finished merging a 1998 R1 with a 2018 R1 and I saw the bike last night


    He got the 2018 R1 from Forseti as well as a big load of cash for the project

    Yeah had the bike in the back of a rental van at a mates place last night - he went to Yamaha head office with it today, and Monsignori Rossi is apparently going to ride the damn thing at some stage

    Well there you go. I thought Forsetti was most likely the product name for Jap Spares Chinese products.
    I was looking at a big bore kit from them for the Honda 400F.

    Maybe we should get back on Topic

    This confuses the hell out of me
    - So suggestions is to use a completely different brand/type of reg/rec - so what comes with that? I have no idea what the diodes spec are on the one I taken off the bike (other than the SH572E-12 code, nor what the spec are on the ones beeing suggested - If you can interchange any reg/rec then why all these different types on the market? (prices on the same I got fluctuates between $30 up towards the $350 mark (cheaper as you step up towards heavier bikes for some reason)
    The one I got ("SH572E-12" can be sourced for 125cc/250cc all the way up to 1500cc Suzuki;s, but some is also sold specifically for quads of various brands - What is the difference? - Dont really care about the connectors as thats easy enough to sort
    - Im more curious about the internal behavior and if it would send the correct charging signals back to the battery across the RPM spectrum on my small bike (especially if I went for something like the Forseti or Shindengen Mosfet FH020AA or one sold for suzuki 1500cc (ESR550-A4) for example?

    ... and lets not forget its a 1999 model/year with a tiny 12v SSB RTX5L-BS battery fitted - Dont want to risk under/overcharge the battery due to misbehaving reg/rec - (listings seem picky when it comes to fitment/year)

    A 12 volt battery is a 12 volt battery, doesn't matter if it's a standard flooded cell, sealed lead acid, or whatever (the exception being lithium batteries). They are all just six cells in series with a nominal 2.1 voltage per cell.

    The brand and specs of the reg/rec aren't super critical so long as its designed for a 12 volt system. All the reg/rec achieves is rectifying 2 or 3 phase AC to 12 volt DC, and regulated to a maximum of 15 volts (generally).

    There are differences in technology. The standard diode setup that shunts excess current to ground means the stator is always working at full output, and reducing the load (unplugging lights etc) actually puts more strain on the whole charging system. You will find this type on old bikes and generally they fail by not charging at all or failing to regulate the DC voltage. They run hot.

    An improvement on this is a mosfet reg/rec which works on the same principle but is far more efficient. The most common one we find is the Shindengen FH020A and they are a good unit. Manufacturers are using them for a reason.

    I have a Shindengen SH847 which is different again. Instead of shunting unused current to earth, it opens the circuit, which has the result of the stator running cooler. They are really pricey units though.

    Thanks - appreciate the explanation = but it comes across as weird considering theres sooooo many different ones sold on the market - seem that 90% of variations could have been combined into one basic unit.
    But, seem I could shop around for pretty much any 12v reg/rec then

    cheers

    The Shindengen SH572-12 reg/rect is a 12V 20A unit, with a 25A output at maximum.
    If you want original you'll be paying around $150

    There are probably more than 50+ different type's of regulator/rectifier's you could use on your bike, then there's all the aftermarket copy's (generally cheaper than the original Shindengen reg/rect)
    Most have an output close to what each different bike need's, which is why there are so many different one's,
    some may have different bolt pattern's, some may have different wiring connection's, etc etc
    eg some plug directly into the reg/rect, some plug into a socket on a fly lead

    Other compatible reg/rect's for your VL250 Intruder are the Shindengen SH640EB, SH719AA, SH650A-12
    These will also fit your bike with little to no mod's required.


    What do you do for a job, are you an Engineer, or studying Engineering by any chance ?

    I was blown away by the shop quotes on the stator and reg/rec so checked with an official local Suzuki dealership/maintenance and they pretty much came up with the same figures - so $150 is wrong - the reg/rec stock item retails for $350+ and the stator (which gladly worked out as good) would set someone back $750+
    Stupid, stupid prices - These two parts is 2/3rd of the bike value

    I decided to try the Shindengen FH020A that was suggested earlier - only paid $30 for it and would have to do some minor tweaks on the wiring - but thats a no brainer really

    ... no Im not an engineer ;) Im handy on occasions though and often able to work things out (with a bit of help/head bouncing with others on occasion ;)

    You don't have to buy your Shindengen regulator's from Suzuki, you can buy them from other place's too,
    place's like Motorcycle electrician's, ebay, and the internet, Electrosport, Roadstercycle, RMStator, and locally like- https://www.custombikeelectrics.com.au/ , https://www.smallcoilrewinds.com.au/ etc etc


    So the Reg/Rect you bought was new ?
    Guessing it's just a cheap china copy for that price?

    This is one of the cheapest place's to but that Shindengen FH020A reg/rect $135US inc post

    Possible a cheap import - but I guess I could use up like 20 of them over time if they are prone to break and still come up @ top vs going to some oz brick and mortar shop.
    Perhaps would have been a slightly different approach if I had a 30K bike investment - but the bike in question costed close to nothing so why go over the top on things like this - next something else like the stator is gone - a snow flake chance in hell I spend close to $800 for a new "genuine" stator - if anything I probably try to get it rewired...
    In terms of the Shindengen reg/rec, to price I mentioned was on the stock replacement reg/reg - Not the Shindengen one.
    Anyway, thanks for the input and clarification on this - Should take about a week (or 5) depending on APO service, but once I get it I will post an update on how it pans out.

    cheers

    The stock Suzuki replacement reg/rect is made by Shindengen, same as the one that failed 20 year's later on your bike

    Where did you get one at that price? If new, it sounds like a knockoff

    Genuine shindengen stuff is not cheap
