by popular demand ...FOR SALE a plug and play mosfet EX conversion.

No illusions or false claims...the supplied genuine Shindegan mosfets will be sourced used...but the cool runner will no doubt offer a long service life.

Each regulator is to be vigorously cleaned and confirmed electrically operational, each bench tested and "live" tested on an EX, my Honda or Ducati when possible. I'll provide specific output voltage details to ya'.

Conversion harness hand built using genuine Furakawa weatherproof connectors and 14 gauge silicone jacketed wire...both crimped and soldered for reliability.

Mosfet and cable conversions will be available on a very limited basis at this price point.

$120 shipped in CONUS only, Paypal accepted. Further mounting suggestions shall follow. Interested parties please PM.

Disclaimer- as with any electrical mod, I cannot.. and will not... be held responsible for any...any...consequential/peripheral damages. Though this mod is a proven, clear winner, the final responsibility as to the overall condition and integrity of your electrical system (and this installation) is YOURS.

your antiquated, 80's technology EX regulators are known to run very hot, cook from the inside out...meanwhile providing erratic output (to recharge the battery and provide system voltage)

when able, try feeling the cooling fins after you've taken a ride (heat is a byproduct of converting AC to DC voltage)

The more modern Mosfet provides stable output, runs way cooler, offers a much longer reliable lifespan.

read the old thread ZX10 regulator on a EX500 sometime http://www.ex-500.com/index.php/topic,27515.msg406149.html#msg406149

(my own Ducati and VFR mosfets in their 6th trouble free seasons)

PM comin' your way, DH.

I got involved with these years ago due to the terrible reliability of the stock Honda VFR rr's. Mine ran *burning hot* 30 seconds after the bike was started from cold.

Converted the VFR, was so impressed, I then converted the then 15 year old rr (I didn't trust it) on my Ducati with the same old, reliable Shindengen from the ZX10. Both those in to 6th seasons now...zero issues (except for a ground issue...MY fault...on the Duc)

The modern Shindengen Mosfets offer stable output, run cool...and as a result ultra reliable, long lasting. I'll proclaim longer battery life too...result of a bit higher charging rate than the shunt type offer.

SUGGESTION...add a voltmeter of your choice, for early warning of charge system problems. Could save a lot of cussin', pushing or a rescue even.

My remaining few units have each been live tested on an EX500.

Each is reliably outputting 13.8v-13.9v @ 1200RPM.

Once again, a bargain ..once gone...likely it for this season.

After I don't know how many months of the mosfet Ducatiman sold me laying on my work bench, I finally got a mounting spot figured out. I have a gen1 and the side panel fairings give you less space to work with than the gen2 fairings, so I had to get a little creative with mounting. Finally settled on the small void inside of the tail fairing. Yes, I know this is where the tool bag is located, but I've never had one and almost always have a backpack with a few tools, so the space is unused.

I did have to modify the frame ever so slightly. There is a small hook that protrudes off an otherwise flat surface for the rubber hold strap for the tool bag that I lopped off. I got the mosfet situated as far back without pinching the wires for the tail lights and license plate light. I then drilled a single 6mm hole in the plastic rear mud guard, ran an m6 bolt through the regulator and the mudguard, snugged it up with a nylon stop nut and that was that for mounting.

The original wiring adapter for the mosfet to the EX wiring harness was obviously too short, so I contacted Ducatiman once more and he graciously made me one to a longer specification and I will be returning the standard length one back. The length of the new one is 15 inches and was just right. I forgot to take a picture of how I routed the wiring, but you can see how it is started here. It runs up and over the top of the frame on the left side of the bike, right in front of the mount for the grab bar, then drops down directly underneath the hinge point for the seat latch and related key lock.



With the original regulator out of the way, I found it to be a perfect location for the remote reservoir for the Works rear shock I have installed, finally getting it out of the way of the side panel fairing. You can also see where the mosfet wiring plugs in with the stock harness. Neat and tidy.



The seat and side fairing clear everything quite comfortably and you can't even tell anything has been modified unless you remove both.
Thanks for the help @ducatiman!

Saab- a two-fer, very well done!

note to any interested members...I'll be marketing more of these in the future and....

will custom build harness length to your required dimension...just supply me with OAL (overall length)
thus enabling your own preffered alternative mounting options

Note: Mosfets are temporarily sold out, more to follow shortly.
 
#23 · (Edited)
a couple Mosfets are back in stock and available... seems a very fair price

Please advise your harness length...based on your preferred mounting location.

Take a good look...provide me with OAL (overall length, measured in inches"

PM for further detail or info.

If one is planning on an alternate mounting location like I did, it's a good idea to add a couple extra inches on top of your measurements. This is helpful to allow slight alterations in final routing, not to mention a bundle of wires has inherently more mass than a tape measure. My initial measurements were for 12 inches, but I figured real world application would require a tad more, so I went for 15 inches. In the end, if I had gone with 12, it would not have been enough.

Cool running, stable, reliable. A GREAT winter project/upgrade for your "keeper" EX.
