I didn't loose a charger but other things like:
battery cables that had steel ends rusted into two pieces.
a Perko batery selector switch that somehow got water inside and drained
batteries and apparently shorted out the rectifyer charging circuit.
Even though used, I just replaced the axles and springs (one axle was new
three years ago!)
studs on the engine, exposed threads are rusted badly
etc, etc,

Sound terrible. You must be living near a beach with all the salty air
coming from the ocean to rust everything out.
