Default Is there a upgrade Rectifier 2005

I have a 2005 and I heard talk a while back of a upgrade for the rectifier,,,
Is it a plug and play item, Or do I have to rewire the whole thing,,,,
Thanks
Mike

try doing a search on "mosfet". I've replaced my old R/R unit with a Mosfet unit, and it was fairly easy. Had to change the terminal plugs on the wires, and drill a hole to mount it. (mine's an '04)

Just did this last weekend with a used R/R from a ZX10 I got on eBay for around $40 (it came in a Kawi box and looked brand new). Still waiting on the Triumph link lead to finish it up right, so I just plugged the female spade connectors into the replacement unit. Replacing the old burned-out rectifier was super easy.

SH010 or SH012 will do the trick. I bought mine used off E-bay for $25, came from a ninja, although that part # is also used on the Grizzly ATV's.
It's not plug and play as these use two connectors, but it's no biggie to wire them.

Those part numbers are for the shunt regulators. Probably a better option would be the mosfets. The mosfet numbers are FH010 and FH012.

I put a FH012 in my 2013. I think I paid $39 for it on ebay.

As everyone else stated...Mosfet. Wire it yourself, get plugs or wire harness from easternbeaver.com or triumph dealer.

Is the regulator rectifier a common issue? Would it be a good idea to repalce it on a regular basis like on a VFR Honda? I venture many miles from home and don't need trouble.

Go to the mosfet version and don't look back. They are much more stable and reliable.

I got a plug-n-play replacement from racetechelectric.com. No wire changes, no drilling, just swap 'em.

I've only had it on there for a short time, no problems so far, but can't really give any opinion on longevity. But it's fine so far...

The MOSFET regulator doesn't use an external sense line like the OEM SCR type, so it tends to be more forgiving of marginal batteries and connections (though the battery is still an integral and necessary part of the system).
The regulation voltage tends to be higher than with the stock regulator, and makes better use of the available power from the stator, because it's able to switch on and off at a very high frequency, whereas the OEM one can only switch at the stator frequency, and discards power unnecessarily in some conditions, like lower RPM.

Looks like these rectifiers are the updated type, Plug and play and come with a life time warranty, Am I reading this right, That's had to beat...

I just grabbed this one from ebay:



It's listed as an FH012AA ... will that work on my Gen1 with the correct DIY wiring?

Should work,
Check youtube for video with
"FH020AA / FH012AA Mosfet Regulator Rectifier check out" by Roadstercycle
(Links don't appear to work)

this guy shows how to check the rectifier portion of the unit with a simple DMM diode check measurement. To check the regulator operation, a variable voltage supply would be needed.

Maybe I'll just hang onto it and keep an eye out for the rest of the parts needed to build a YZF1000.

I was headed out the driveway on a two-week trip when the green light on my aftermarket voltmeter went out...battery not charging! The voltage regulator had failed and I figured I was screwed, since the local dealer stocks ZERO parts for the KLR. I was pleasantly surprised when he figured out that the regulator off one of the Kawasaki quads (I don't know which one) is identical. He sold me that and I was on my way just a couple hours late.
