Looking for information on an "ALTUS" battery power monitor.
The device in question was most likely made in the 1990's for the marine / rv industry, made in Minneapolis Mn. , the company seems to be out of business as a web search has only pointed me in wrong directions.

This one has a 2' round meter scaled in 0-100% and e-f , has a "READ" switch directly under the meter, a 3 position rotary switch labeled main-aux1-aux2, and two other two position center off spring return toggle switches on the right side of the panel with green lamps above each switch.

If anyone has any information, instructions, schematics, whatever , it will be greatly appreciated, I can send a pix if needed.

Thanks for reading, John
