We are plugged in to shore power set to 30 amps. Lately, the Multi Control panel flashes bulk despite having been on float just the other day. Batteries percentage is lower than 100% as well. If I switch off the Digital Multi Control and wait an hour or so, Bulk lights up but doesn’t flash. After a while, it flashes again. Someone on line said, “Blinking “bulk” means “bulk protection” - the Multi is charging in bulk more than 10h without reaching the absorption voltage.”
Batteries are 4 years old. What do I need to do to correct this issue?
Thanks
