exactly.
i turn on master switch, when backup battery is connected - nothing happens (most of the times), when I disconnect the backup battery - skyview is loaded up.
I’d do all the same ie
1. Turn on master switch with backup (SV-BAT-320) battery connected
2. If nothing happens then disconnect the backup battery or if SV lights up then check what the backup battery volts are via the SV menus.
3. If the backup battery volts are low then I’d connect a battery charger to the main battery, leave the SV on, & charge for a few hours - in this situation, if the battery is good, you should have no more ‘issues’
