Replacement reg/rect - any will do?

[CookMySock]

My Hyosung GT650R developed a short-to-ground fault in the stator windings (now repaired) but it looks like its toasted the regulator/rectifier, as expected.

Now it seems the reg/rect is a perfectly generic item? Three yellow wires, red and black/white stripe wires.

The stator is capable of about 350W, so are there larger capacity regulatorsthat that are better and smaller ones to be avoided ?

Any suggestions? Anything will do as long as the bolt holes match?


thanks,
Steve

You nearly correct. More like "Anything will do"
The 3 yellow > Stator
The other 2,
1 > Output
1 > Sense wire

Check with your local bike wrecker first. Eg can even be a quad bike or whatever. This type of Regulator/Rectifier is common amongst Honda, Suzuki, Duk .... All you need is a 5 pin / 5 wire one.
*Important* Get one with a proper finned heatsink if possible

I read your stator thread. Good skills won the day there.

Thanks Warr. Yeah it was a wee bit bodgied up, but hey the wheels aren't going to fall off coz of it.

Yeah theres a wrecker down the road who aparrently has a big box of rect/regs to try. I'll go see him on tuesday.

If you want a long-lasting never-fail reg/rec, look for a Shindengen SH232. Old-fashioned type with heaps of big fins to soak up the heat. Fitted to the CX500/CB250/CB750/CB400/dozens of other Honda bikes back when they had good regufiers. He'll have half a dozen, should be pretty cheap too, $20-40.

You can get 2 or 3 wire reg/recs from an autosparky - they use them on small tractors and stuff.Not cheap,but at least you don't have to pay the premium ''motorcycle'' label.

There are also some newer ones with more wires that will do fine as well: 3 stator wires (usually yellow) and two each of the power (usually red) and green or black earth wires (good, because the double up means you can put one earth wire to the battery -ve, and one to ground on the frame), and one more 'monitor' wire that you hook into some circuit (such as taillight) that's live when the ignition's on.

I heard the reg/rec used in the 98-01 yamaha R1's are pretty good units pricey though brand new at $200. Very popular replacement unit for the bad design early CBR's.

Roite, I got a yamaha one for $160 new. I had to change the plastic connector housing on the stator connector, and I replaced the terminals on the regulated output wires with spades.

Quick stator-to-ground isolation test - hi Z - pass!

Shove plugs in, start, and 14.4V on the battery! Sorted!

Thanks folks.

That's not pricey.
That's about normal for an 'aftermarket' Shindengen unit, whereas a "genuine" Honda one (also made by Shindengen) last time I looked (about 9 years ago!) was over $400.

True?? ill wait and see what the dealer says is up with my cbr , if
its the r/r i might have to see what they have to say about it.

on the same topic. I just replaced the whole charging system on my bike, stator to battery. Now the new r/r unit I got from the wrecker is putting out the right voltage, but is heating up a damn site more than the old one I used to have. The old one was off a GN250, new one off a GSXR400. My bikes a gsx400. Is it gonna be alright? As I really don't want another 6 weeks without a reliable bike

That looks like the old unit the gpz's had too, 'cept they have 6 wires, gotta be the toughest s.o.b. reg/rec ever made.....

Yeah the brand new one I got had smaller fins, and was physically smaller too. I'm sure it runs at a higher temperature.

Just reassure yourself that you can take it back if it goes pop, the guy knew what he was talking about, newer-technology reg/rects run hotter than the old ones, and all that sort of crap, and then just go ride.

Sometimes you just have to trust that things will work. in a month or so, you will have forgotten about it.

Heat is what kills the R/R so keeping the air moving over them will make them work longer.
My model VFR the R/R is tucked away under a fairing and it is common practise to put a cooling fan over them. I did this on my previous VFR.
An alternative idea is to mount the R/R up under the headlight where they can receive a direct flow of air.
More wiring required or course but another worthwhile option I think.
