ZX10 MOSFET voltage regulator on DUCATI

can't be done you say? pics or it didn't happen? here you go.

I did the same mod using identical voltage regulator on the VFR with success. I wanted to update the Duc as its now 16 years old, i was apprehensive about the age and remaining service life of the original. The ZX uses updated mosfet technology, just some major wiring changes needed. Note the Duc is a 2 phase system, the ZX is 3 phase. After determining mounting and wiring...
its pulling over 14V at 4000 rpm, a test ride revealed it running cool. Here's to a long life. $59 bucks on ebay.

The scruffy wiring you see is temporary, i'll order proper connectors and loom to neaten it up.

Re: ZX10 voltage regulator on DUCATI

updating this thread....I had some charging system difficulties this year (2015)...2 separate metripac connector terminals loosened, all fixed. I opted to pull and rewire my stator continuous run *direct to RR* (no connector) upgrading from 16ga to 12ga silicone jacketed wire...see pics.

Also chose to ground the RR by running silicone 12ga direct to battery negative, using the frame as ground became unreliable and intermittent.

5 years on....charging is dead stable and reliable again. The Duc now 21 years old.

Always open for improvement/tweakage where needed.

9 years hard to believe....went by so fast. Thankfully the wiring was made visually neat and presentable long ago, a grounding improvement too. Thing still works impeccably. Mosfet upgrades worth every bit of effort and $$.

Thanks for that.....I'll be doing the same for my SS once I reach that point. To reiterate though, you wound up running the ground all the way to the negative battery terminal? I was, and am still considering a ground bus of sorts....sean

hi, I did exactly the same on the EX. at first I wired the Mosfet into the 6pin connector with a little tail but was worried about that troublesome white feed wire on the EX that corrodes burns out or melts the connector. "probably the reason the old one burned out" so I then took the 3 yellow stator wires from the 3pin connector just above the case. and run them straight to the RR and then wired the other two from the RR straight to the battery. a much better system. the added bonus of this was the old 6 pin connector was now redundant but it did contain a power feed and a earth wire. very handy for wiring in the alarm system I got later on.

using a ground bus system is fine as long as the bike has frame grounds around it. the EX doesn't it's an all wired system so there isn't much point but it could work well though with a little ingenuity.

on the Ducati I ran a separate ground right to battery, yes, I may have left a frame ground as well, can't remember. Redundant, but no matter.

For the EX I've long ago created a "plug and play" adapter harness in short (standard, for original mount location) and long (for optional undertail mounting) versions ...remove/unplug old rr, mount Mosfet rr, plug 'er in....go. Pick yer poison.

Ducatiman,

Thanks!
