Yay.... Mystery solved...... Thank you sir.
2) I'm sure the stock regulator got very hot... I've never put my hand on it...
I'm sure that the MOSFET regulator still gets hot ... maybe not AS hot...
So I'm thinking that with the metal bracket bolted to the frame that it does act to extend the heatsink function somewhat .... not sure how big the effect is, but maybe you don't want to use a composite bracket?
You are right that the composite is like an insulator, but mind you the stock bracket is not touching the stock R/R , because of the little nut inserts... It's like 1/2 mm gap.... Plus there is a big hole cut out in the center.. Mine will mimic that.
Just because I could, when I took my R/R off to get the P/N off the back I re-assembled it with heatsink grease between the R/R and the bracket and also the bracket to the frame.... I know I know ... don't go all
on me ... it only took a minute.
I personally believe that most if not all the heat is dissipated through the front heat sink. For the little time I ran it...it did not get very hot. I did not do any heat testing on the R/R, but have been assured that this unit will hold up to the heat quite fine. This unit is fused at 30 amps. Max draw of the stator is about 28 amps at full screw. I believe this units origin is Japan.
