I have a slow drainage from my battery. It won't hold the charge from one weekend to the next and I have been trying to track this down from when I first built the plane (7-A) 9 years ago. I have replaced the battery (Odessy 680), replaced the solenoids, etc. When fully charged it reads 12.4 amps. If it sits for a week it drops down to 11. 3 amps, which isn't sufficient to start the plane.
I am the most ignorant builder ever when it comes to stuff electrical. A hanger neighbor stopped by and put a gauge on and said the battery is drawing 3 mili-amps (whatever that is) when the master switch and everything is off. The only thing I can think of is the analog clock which doesn't go through the master switch, but I can't believe that clock should drain the battery so quickly. Keeping in mind I am totally ignorant on things electrical, does anyone have any suggestions on how to proceed finding where/why the battery drains? You can imagine how frustrating it is to promise a friend a plane ride only to find a dead battery. Thanks in advance!
