Betreff: 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 !
