Converter/battery set-up in old Clippers - warning

[Horst]

I know that this should probably go in Tips & Hints - but I'll put it here as I had questions about converters/chargers.

Those of us with old Clippers that do NOT have the coach battery access door - watch out! If  your battery is not secured VERY well, it will move around while you're underway, and may slide back and unplug your converter/charger.

This happened to me. (I was wondering why my battery was discharging too quickly!)    
The fix was to block the front and back of the battery with some wood pieces to prevent the battery from shifting around (in addition to the normal strap set-up it had.)
