GT Regulator

[sportsprint]

The only issue I faced in 60,000 miles on my old ST Sprint was losing the regulator. In fact, the regulator and alternator both.

In the end, I ended up with a Shindengen regulator. In my opinion, this is the only MOSFET unit that works correctly. I have installed this even on my older Bonnevilles.

My question is this. The GT comes with a high output alternator. 400 watts, I think. Does anyone know what type of voltage regulator is used??

I read once where the GT's would come with MOSFET technology.

I don't have any data to back this up, but I've heard on this site that the regulator is not suspect on the GTs. I can confirm it is in the "updated" location which gets more air for cooling.

I asked the senior Triumph tech at my dealer about the GT's reg/rec when I bought mine and he was not certain but hoped it was a mosfet unit.

I have not had any trouble with my own 2011 GT to date.

I can only visualize a MOSFET on the GT. That's because of the 400 watt alternator.

In my experience, people started to lose their 955i alternators. When they did, they most often bought a Ricks stator unit. The Ricks unit is rated at higher watts.

Like all things in life, higher is better, right??

With the Ricks until came more wattage. Triumphs ALL had shunt regulators. At first, the Ricks alternator connector plugs melted. This should have been a warning sign. By the common knowledge was to solder the wires together.

Then, the Ricks alternator wires got hot. Some even melted together. Again, this was a second sign. Most just ignore this, also. Finally, the stock Triumph regultor just let go.

When switching to any larger alternator it is 100% IMPORTANT to convert to a MOSFET regulator. 100% important!! If you don't switch, no matter how big your shunt regulator is, it will eventually just melt....

I too read somewhere that the GT had a bigger alternator than the (late)ST(35Amp.). Then I started thinking that it was the same engine and the side cover looks the same as an ST………
So I went to the World of Triumph parts fiche and lo & behold the GT and (late)ST have the same alternator part number!!!
Triumph probably re-calculated the formula on how they arrived at the wattage rating.

I've actually just measured stock 955, Electrosport, and Rick's stators. The stock and Rick's units are almost exactly the same size, maybe off by a sixteenth of an inch in one dimension. The Electrosport is substantially smaller. Given they use the same gauge wire, units of the same size are going to put out the same amount of juice. (The E-sport definitely does not have the same output as the other two.)

Referring to a comment that given the same size, alternators all put out the same voltage?? is this correct?? So, if I buy any lightbulb that screws into the socket, they all put out the same amount of light?? Even though they are all the same size??

[KitNYC]

Light bulbs are not stators. A given number of coils of a given gauge of copper wire will end up being the same physical size every time.

Actually light bulbs don't work like that either, wattage is a very different thing to Lumens output.

Not to mention the socket part of a light bulb is not the part that makes the light.
