Sorry for the load of electrical posts but I’ll be bugging everyone for a bit.
Is there an issue with putting the voltage regulator on the engine side of the firewall? Or is my only option to extend the shielded wires off the internal alt.?

I believe that many people have located them on the engine side. Perhaps there is more potential heat there, especially after shut down, but that is mitigated by air flow when the engine is running. Air flow is good. I put my Silent Hektik unit behind the firewall and extended the leads. That's where my over-voltage relay and capacitor are, so it made more sense to me to group those together, wiring wise, and the SH unit has a higher amperage rating as well as more heat-sink area than the Ducati.

I put my voltage regulator on the firewall above the Battery so it is in the air flow. It is working out much better than behind the firewall. Also the Rotax connector has caused some people issues. I just installed connectors right to the blades on the voltage regulator.
good luck Josh.

John, where and how did you get your hands on that Silent Hektik regulator. You must know someone who bought it for you in Europe, the sent it to the US privately?

put it on the engine side.
if the regulator burns out the fumes are toxic
