I have an extensive solar/lithium system installed on my live aboard catamaran sailboat. We have two engines with alternators each connected to one of two BMS 12/200 (not smart version, no VicttonConnect control). Lately, the power seems to be off on both of these BMS—no led lights. I have referenced the manual which suggests using the remote on/off to repower the units but we do not have a remote on/off switches installed. It seems the alternators from two engines are not topping off the lithium batteries very much (or at all?)The alternators are successfully keeping our starter batteries topped off tho. Any tips to re-power without remote off/on or smart connect app? I am nervous about taking off all the wires and retightening the connections. Also not sure how to test if the fuses are bad. Seems I need the unit to have power to test the fuses?
