With battery charger connected, the coach battery indicator is flashing and shows 15.1V, no difference whether connected to a load (fridge on or off).
Have I installed the wrong coach battery (acid deep cycle RV battery) and need to change the dip switch setting or is the charger faulty?
Many thanks for any response.
The led/acid RV battery was low on electrolite. Once replenished, it is charging through battery charger at a steady 14.8V (electronic display as well as my own measurement) and there is no more blinking of the display.
