genset voltage meter on dash

[Rose Mary]

Hi group
mom and I are still in Q where the circle has shrunk to 3...
been too lazy and warm to move yet.

anyway, replaced the genset battery which I knew was failing after 8
or more years. voltage meter on dash still reads low black/striped
to nearly red. A voltage reading at the new battery reads about 12.6
to 12.8
The voltage numbers seem better if the cat is running. Why would the
cat charge the genny better than the genset running?

Probably another of those duh moments but the voltage gage on the
dash has always been up better.

thanks in advance for your help.

It's like I told folks here, were it not for these great forums I
would have never had the courage to keep and use JP'S White Bird. It
has absolutely given my mum and myself a new direction!

That said, thank you all
