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....
