Equipment:
- Lightspeed Electronic Ignition
- Garmin G3X Touch

I've got ignition on "right" and "backup" ignition switch "on" and the voltage shows 14.4 volts on the primary battery (charging) but the backup drops to 12.2 volts - should I be concerned?

When the key is on "both" and backup switched "off" both the primary and backup batteries are 14 volts (engine running).

Anyone understand what's going on? Can you help explain?
