Electrical Panel

[TFU]

I have a 1988 Hunter Legend 37 and a question with respect to its electrical panel.
Just below the AC master breaker is a small rotary switch which can point to a number of battery designated positions, each having an idicator light. It is not the master battery switch (ie, 1, 2, or off switch). I'm thinking it has to do with allowing the analogue meters to connect to each battery bank but do not actually know. Have tried to trace the wires but have had no luck to date.
What is this panel switch system for?

Thanks,
Bill

As you surmised, it connects the designated battery bank to the voltage meter.

if it's on the AC panel. it's probably for switching the ac volt gauge from line 1 to 2. maybe the boat doesn't have line 2 but the panel was prewired.

I doubt they would put a battery gauge switch on the ac panel. but who knows. put up a pic of the whole panel

Thanks for your comments. I did eventually get around to tracing the wires (long time to do since PO had disconnected several pane wires).
The switch does in fact connect different battery banks (when connected properly) to the DC analogue gauges.
I have added a picture as requested for others in the same boat (pun intended).
Have also added a two pole main breaker in place of single pole shown in picture.

Thanks again,
Bill

Tried again to include photo as did not seem to take first time
