I think I have a parasitic electrical drain. If I do not fly my RV7 for several weeks, my battery seems to have drained down. I have used PC680s and now have a LifePo4. I have killed a couple of PC680s, one by inadvertently leaving the master on, the other by age and unknown reason, it just died. I am now very careful to make sure the master, avionics master and all other switches are turned off before I leave the hangar.
I have a FT50 clock/voltmeter/G meter that is attached to battery but I understand that it has a very minimal drain. The only other hint is that I hear a very slight noise if I plug in my headset before starting. My avionics are controlled by an Avionic master switch and all other electrical equipment is controlled by the master switch. I still make sure all other switches are off after each flight.
The alternator charges as it should, 14.4 v.
Is there an easy way to check to see if I have a parasitic drain on my electrical system after all switches are off?
