My 2005 Holiday Rambler Ambassador engine batteries are not being charged by shore power or by the generator. When I bought the unit new it was not set up to charge both sets of batteries. In 2010, I installed an Intellitec Isolator Dual Delay Relay to charge both sets of batteries. Worked great till this past week when I saw that the engine batteries are no longer being charged, except by running the engine. Looking for ideas on how to fix it. Thank You.
