Backup image, generator battery

[amweath]

The last couple of times I've started the main engine the TV monitor
continues to display broadcast TV. As I understand it, when the
ignition key is on the backup camera should display. I would think that
a relay must be ignition key activated to switch to backup camera.

When running the generator I have noticed that the gen. engine volt-
meter reads 12 volts or a little less. I did install a new batt. last
week, but it seems to be turning over slower and slower.

There is no belt driven alternator on the gen set. How does it's batt.
get charged. The manual is not real clear on that.
