We have a D30-BRA-E in our new to us trailer. I'm finding that when our trailer is plugged in there is 8.85v going to the battery
. I didn't think these units were chargers too and that voltage seems to be low to charge a battery
Are these chargers too. Is the voltage correct? Also it seems some appliance only work when plugged in. Ie Tank monitor, Battery
. When testing when on battery power the battery is fully charged.
Thoughts , observations and ideas on moving forward are appreciated.
