Have a RV9 with Dynon 180 and 500 hrs, been flying since 2008, Began to get spikes on the current indicator on the Dynon EMS. Normal amps with VFR equip running is 10 to 12 been that way since first flight and normally remains fairly constant. Last couple flights the current has been eradic and spiked up to +23, +30 then back to normal. Ive had the alarm set down low so at +18 it went into alarm.. The Dynon voltage remains fairly constant during these events. As wired The Dynon shunt indicates all current from alt to battery and instruments. Style "B" in installation.
I replaced the alternator last weekend thinking the internal regulator may be at fault. flew today with the new Denso 45 amp auto self regulated alt and no change to the eradic amp spikes. Turned off all electrical one at a time EXCEPT the Plasma II + and still experienced spikes but smaller. Turned off everything again except Plasma and still saw gremlin. Also checked the Shunt and sensing voltage wire to Dynon for any looseness found none.
Leaves nothing in but alt,wiring,main 50amp alt bkr., EI, 680 battery. and Dynon180. anyone ever seen this before, Any comments appreciated. STILL LOOKING///???
