Colyn,
The tester's ammeter kept reading that level as I pulled and then reset each circuit breaker ... Until I got to the last CB, for the hydraulic pump. When I pulled that CB the amp reading dropped to 0.0.
I had everything off including the hydraulic pump, when I put the ammeter into the battery's plus side which feeds all circuits. The battery was leaking 18.7 milliamperes. I think that circuit. Goes to a solenoid that closes a heavier circuit to. Power the pump, so do those solenoid s commonly 'leak'?

Terrence,
I'm inferring that you saw an instantaneous current. ...indicating you see some current when the pump is not running. Could it be something in how you have your indicator (e.g. pump running) lights wired?

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.
