Morning,
Finaly got the shop manual has the schematic. Now i am in my skill set ha ha I found the probem this morning. the trim motor circuit is drawing 5-8 amps all the time. Doesn not take long to kill a battery at that size drain. Nothing is hot. Dont know exact fault at this point...
Helping my old Boss repair his boat. Crownline with a vovo V8 inboard/outboard when battery hooked up draws about 6-8 amps nothing turned on. I am electronics person disconnected Alternator thinking it might be draining battery, no help. Corrosion every where, guessing normal on boats...
