You're welcome.  I figured this solution would be the best for you
because you could also install a jack to charge your dad's chair and the
output is a "tad" higher than the solar charger option.  You'll need an
automatic isolator, but that's a snap to find and install as well.  I
know you're not in Canada, but a store by the name of Canadian Tire
(http://www.canadiantire.ca) has one (search on "battery charger" in
"automotive").

In my experience, the "clamp" style ammeters aren't all that accurate
when it comes to reading small currents.  I like my digital multimeter
and doing things the "old fashioned" way.  :-)

Mind you, it'll mean you'll have to reset your dash clock and reprogram
the radio buttons, but I figure you're more than capable.  ;-)
