I threw it in the trash can yesterday. If you want it, I will get it out and mail it to you. I could never get it to work. I have another home made solution that I plan to try. I got it from George on the Zenith list. I can send it to you if you want. Take care, :-) Tommy Walker in Alabama N8701 40.5 Hrs ________________________________ Message 2 _____________________________________ Time: 07:55:48 AM PST US From: "Europa (Alfred Buess)" Subject: AW: RotaxEngines-List: Hobbs power source Dick, You can find an Installation Guide for PowerGenie at http://www.powergenie.central5.com/, bottom of the website.

M=E4rz 2008 14:06 An: rotaxengines-list@matronics.com Betreff: RotaxEngines-List: Hobbs power source I bought an item from Spruce called a PowerGenie. It is an electrical device that fits between the regulator and the positive post of the battery and a third wire going to the hobbs as power. I guess it senses when the engine is charging the battery and opens up power to the Hobbs thus negating the use of an oil pressure switch which I removed from my engine. Has anyone used one of these? Which wire would it connect to on the rectifier as the directions only specify connecting to the plus wire coming from a regulator? I sure don't want to mess up my electric's as it is pretty much "magic" to me. For a little background, I went to Lockwoods Rotax school and their display engine, which we tore apart, was obtained from an owner who had the Hobbs sender and oil pressure sender on a brass adapter going into the oil pressure sensing hole. The Hobbs should have been plugged into the oil hole supplying oil to the propeller (constant speed) if it was not needed. Anyway this two into one brass fitting did not hold, broke off, drained all the oil in the engine. Rotax engines do not like having no oil! When I got back home, I checked my engine and walaa I had the same setup (my Kitfox was a recent purchase) I got rid of the brass adapter, Hobbs oil pressure sender and connected the Hobbs to the master switch. This PowerGenie device is an attempt to have the meter running only when the engine is. It's a nice idea if it works as I have left my master on for a short time from time to time and I don't want to add engine time when it is not running. Any feedback would be greatly appreciated !

Report back once you have it integrated. We replaced the stock pressure sender on our 914 with a remotely mounted VDO-360025 ($25 from Summit Racing). Same form factor as the stock sensor but it has an extra terminal on top that serves as a low pressure "warning contact" that opens above 11.5 psi. Instead of adding a Genie, we added a SPDT relay. The power that supplies out turbo control unit also feeds the coil and common tap on the SPDT relay. Our "Low Pressure" annunciator is attached to the normally open contact while the Hobbs is tied to the normally closed contact. When the system is powered and pressure is < 11.5 psi, the "warning contact" on the sender is closed and the relay coil is energized (light on, Hobbs off). When pressure is > 11.5 psi, the "warning contact" opens and the relay coil is deenergized (light off, Hobbs on). Yet another option for the pile.
