My engine quit charging house batteries. DC panel light is usually white (yellow) indicating engine driven charger is working . I noticed light went to a dim orange - indicating a fault - and engine charger quit topping off house batteries. I put a multi-meter on positive and negativ poles coming out of unit and it reads 24 to 25 volt output. I assume a fuse or regulator issue . Does anyone know if there is an external regulator or fuse for engine driven 24 v charger? If output is there I can not figure out why batteries are not charging..
