Wtd: Voltage regulator - Ducati Paso (or similar)

[themechanics]

HAY YA ALL after replacing both cdi units i now need a voltage regulator for a ducati paso maybe the same for a big range of dukes ?are there aftermarket ones available ,any info appreciated.thanks bazza in the nth

How many yellow/brown wires coming from the alternator?

I have a two-wire regulator that I bought for my Ducati. After butchering the mounting holes, I found it was too large to fit.

If its any use to you, you're welcome to it.

If you don't have any luck on here, try any bike shop that sells aftermarket parts. The Shindengen ones (imported by Eurobike Wholesalers) fit Ducati - have a suspicion that they're original fitment. Shindengen supply R/Rs to quite a few bike manufacturers, including Honda, and (or so I was told) Ducati.
Last one I bought was around $300 new (less than half the price of buying a "genuine Honda" part from a Honda dealer, even though they're the exact same part. Go figure...)

I don't have one for you but in the past I got hold of an after market regulator for my 750SS from the UK. I don't remember the name but will try and dig it up (I got it through a Moto Guzzi guy). It worked like a treat and supported the charge light. I suspect virtually all Duc's will accept the same reg.

There is also Electrex in the States who do an after market reg but these were a lot more money at the time (I was in South Africa then).

Some guys use a reg from a Honda (CBR 400 I think, it's a Shendgren or some such, used in many Jap bikes) but I don't think these have the wiring for the Ducati charge light system.

Typically the reg fails because of a short in the alternator wiring - check the 2 (or 3) yellow wires running from the alt. to the reg. particularly at the under speced inline bullet connectors. The connectors tend to corrode and develop a high resistance, they then over heat which melts the insulation and causes a short that fries the reg.

Also the reg. itself can tend to overheat (due to it's location) this will also shorten it's life.

They're also not especially reliable - worse than standard, in fact.

Shindengen. No, one for a Honda won't have the charge light system.

Correct. There are typically too many connectors in the charging system wiring, and the wiring is generally a bit lightweight. Any corrosion or bad connections leads to bad mojo.
My first R/R failed for some unknown reason - probably just because it was too lightweight and hidden under the bodywork, where it got hot. (In the Olden Days, appearance wasn't such a big deal, and the R/Rs were out in the open air, so they fared better.).
I replaced the R/R and all the wiring from the stator and to the battery with larger gauge wires, and eliminated ALL the plugs. Then I mounted the R/R under the headstock on an aluminium plate,
The second R/R failure I had was due I suspect to a corroded yellow wire in the plug into the R/R. The wire was a bit burnt. Being only a few months after the work on the previous bike, I couldn't be fagged with a rewiring, so I just made sure all the connections were good, and remounted the R/R on the frame in the open air.

Hey hey hey! #$(*@#$ my VR also just blew up this morning.
Must be the heat, eh?

Or bad mojo.
There's a lot of it around lately, probably spread by bad mofos.

thanks all whom replied i think ill be goin with the after market one same as honda but more reliable than the duke one after i check the wiring etc
thanks bazza
