I am making a bracket to house the new R/R......and after much thinking I will leave it in the same location...just tilted a bit.... for my taste. It is really up to the individual taste.... but I'm kind of handy with the composites stuff....and can whip a bracket up about as fast as you can saw and bend a sheet of aluminum.... Stay tuned....


1) Per the wiring schematic in the Haynes manual the four wires (two hot and two ground) do indeed go JUST (directly) to the battery and do not wander off to the ZFE or other places. I speculate the same as you ... the needed more current carrying capacity and didn't want to use a single heavier gauge wire as it would make it harder to route the harness.

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?

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.
