Should the power wire from the UMA hall effect tach sensor be connected to the battery buss (always on), or the main buss? I would think the battery buss because you would want it to continue to work if you lose your master contactor. If that happened, the Dynon battery backup for the Skyview would continue to operate the Skyview system and the tach sensor would still operate (as long as the aircraft battery has juice). Will connecting it to the battery buss drain the battery when not flying because it is always on? Thanks!
