Starting to troubleshoot a battery drain issue... after a few weeks of being away, I found the battery completely dead (it won't even charge now..). First thing that caught my eye is VP-X showing around 3.5Amps on "Alternator field" circuit... with the engine shut down... That doesn't sound right??
I believe the total draw (with most of the stuff shut down via VP-X) was showing a little over 7 amps and that just sounds way wrong.. No idea where the rest was going.,. only one HDX screen was on.. nothing else was supposed to even be powered...
Any ideas why alternator field may be showing such draw w/ engine off?
PS. Did not build the plane so still getting familiar with what it even has let alone how it's wired up.. (have some documents, but still need eyes on each part to really understand everything)
