My N211AL is from kit no. 11, and has electric prop, electronic ignition, dual grant rapids Tech EFIS, autopilot, flaps, navcom, GPS, transponder, intercom, and retract gear. My battery kept going dead, so was advised to put an ammeter on it and see how much it was leaking, and then start pulling circuit breakers. It was leaking 18.7 milliamps. I pulled CBs one at a time and reset them. Would you believe the very last one stopped the leaking, and the ammeter went to 0.0. It is the CB for the hydraulic pump. Question: why is that circuit leaking when the CB is in? The pump works fine. I have added a pressure switch to keep the gear down and the airspeed is below about 85 mph ... or to put the gear down when the airspeed drops below 85k. The pump is off when the Master is off. Is there something in the pump circuit that allows it to bleed? (For now I'm adding to the Check List for Shutdown: Hyd. Gear CB -- out.) Any suggestions welcomed.
