Boat is a '73 Katama powered by a 1987 70h.p. 3cyl. Johnson
Seahorse.Isolated the sources of the potential problem by systematically removing accessories one at a time.
Purchased a new Optima Battery this past Friday. Saturday a.m. the thing is drained. Same thing on Sunday. Its now fully charged sitting on my deck.
I have narrowed it down to the ignition switch at the helm or the motors own charging system.
Looked for frayed or burnt wires at the motor and found none. The lone fuse in the charging system relay is good.
The ignition key is in the off position. Could that switch be faulty and cause a dead battery overnight?
Do I need a new power pack or rectifier?
Any help is highly appreciated.
