Charger location

[Jon]

My charger is located in the storage area for your drain hoses and
fresh water hoses. It sits behind a sheet metal boxed in area so it
cannot be damaged by loose things being put in this location. I'm
going to put a switch on the outside of this sheet metal box so that I
can turn oft the charger without removing part of that metal box. Now
my question is that I notice on the removable sheet metal box end that
there is a punche out hole with silver tape covering this hole. I was
wondering if at one time there might have been some-type of switch
located in this position? Does anyone here have a 78 or 79 with a
standard gasoline generator that has this sheet metal enclosure? Sure
would like to know what went in that punched hole. Oh yes the hole
itself is probably about 1-3/4". Thanks Jon
