Store switch ON no shore power. All systems good using coach batteries for power (red light use/store switch illuminated). Batteries at charged state measure 12-12.5 Volts.

Store switch OFF, plug in shore power, Power in coach (red light at use/store switch illuminated. Coach batteries measure same as before 12-12.5 volts)**

**Even though red light at use/store switch is illuminated, coach batteries don't indicate they are receiving any charge/assist from shore power. BUT, if I flip use/store switch (audible relay latch heard), coach batteries immediately show increase in voltage (approx 13 volts) indicating shore power is now charging/maintaining coach batteries.

Store switch ON, plug in shore power, Power in coach (red light illuminated), coach batteries show charging state (approx 13 volts).

Make a long story short, depending on position of use/store switch when shore power is plugged in determines if coach batteries are automatically "latched" through relay for charging state. No problem really except there is no stand alone light or voltage indicator to show if relay is "latched" or not.

I will solve my concern shortly as I am installing a small digital voltmeter (connected directly to coach batteries) so I can determine whether coach batteries are receiving a charge (relay latched). If I am missing something here, let me know.

Use/store should always be on when plugged into shore power or when gen is on. The only time to turn it to store is when its being stored.
