Mich48041 in above two posts, is giving good advice... The John Deere AM101406 ($20 on Amazon) works very well with Rotax 912ULS and Odyssey PC680 Battery. I have mine mounted in original position on firewall shelf with no additional ventilation. It is mounted on a sub-plate using thermal heat paste. I'm guessing close to 400 hours since install. I carry a spare in the baggage compartment that's never been used....

Last week the Amazon voltage regulator arrived and I did not install. It was half the size of the Ducati VR and quality was questionable so I went with the B&C XB100-2. That arrived today and looks exceptionally nice. Was shipped in a presentation quality box as a bonus! Install is almost done, but I forgot to bring my wife's hairdryer for the heat shrink tubing. I will finish up tomorrow, but I am a bit nervous. Changed engine oil and I did not clean the oil tank. I was concerned about removing hoses from the top of tank and then having to purge air from the lines. Lack of experience so I am taking small steps.

Buttoned up voltage regulator install today and pulled RV out for a run-up. All good! 14.1 volts. B&C bolted in place of original Ducati on the firewall shelf. New connector body fitted as well.

Isn't the regulator in the photo a B&C AVC1, made specifically for the 912 ULS series engine? That's what the box indicates, and that is what I have in my two 912 ULS-powered aircraft.

They are the same item. "AVC1 Advanced Voltage Controller" is the name. "XB100-2" is the P/N.

I didn’t open my oil tank to clean and inspect until 1200 hours and 11 years. It was clean as a whistle. I waited to avoid the purge process PITA.
