I have a Taiwanese trawler with dual Perkins Range 4 motors, dual alternators, Inverter with seperate charger and have an issue with the 4 position (off, 1, 2 or both) battery selector switch or maybe something else?
When running, regardless of the battery selector switch position, each battery is being charged. This was checked with a voltmeter on each bank and trying different selector switch positions. With the motors off, each battery is being charged by the charger. Engines off, the battery switch is set to #1, 2 or both, both battery banks discharge with a large load applied for many hours..
I have checked that the selector switch is functional with the battery banks disconnected using an ohmeter. I also checked that the battery banks were not somehow joined together, and did find an added battery cable between the battery banks and inverter. I removed this to no avail.
I have followed the wiring and do not see any type of isolator or cobiner installed anywhere. Please, what am I missing?
