My suggestion is to use one of the alternator output wires as suggested in the Dynon installation manual. This works very well for me. It is accurate and stable when compared to an independant prop tach. The Dynon tach set-up for this configuration is 6 pulses per rev. -------- David Gallagher 601 XL/Jabiru 3300 First flight 7/24/08 54 hours and climbing!

I suspect a power or grounding issue is at fault. Do you use any filtering capacitor or other conditioning on your electrical system? -------- Doug Kandle, Idaho Read this topic online here: http://forums.matronics.com/viewtopic.php?p=236643#236643 ________________________________ Message 3 _____________________________________ Time: 06:10:13 PM PST US Subject: Zenith601-List: Re: Jabiru 3300 Tach Problem From: "DaveG601XL" Doug, I tee'd into one of the big white alternator wires upstream of the regulator. I ran this wire, though a 1 or 2 amp in-line fuse, straight to wire #32 of the 37 pin EMS harness. (either 32:right engine or 33:left engine will work) I put no filtering or anything in this circuit. As long as the alternator is on-line and the Dynon set to 6 pulses/rev for the same side engine it is wired to, it should work. Good luck, -------- David Gallagher 601 XL/Jabiru 3300 First flight 7/24/08 54 hours and climbing!
