I have a 96 Winnie Vectra 36WA and am in the process of preparing it for the season. The house batteries are fine as they will start the truck when truck battery is bypassed. The 12 volt sysrwm works fine when plugged into a shoreline. Will not work at all when no shoreline and batteries are only source. Checked all breakers but who can really tell with those dumb little round things. Manual says that converter is in compartment forward of right rear wheels. Of course it isn't; and I can't find it anywhere else. Have had this rig for years and no trouuble at all. Never needed to troubleshoot. Can anyone come up with any helpful suggestions before I have put a smile on the face of an RV technician?
