Supporting Your Association Has Never Been Easier...
A. So long as you change the lube
oil and filter at regular and reasonably
frequent intervals, and keep after maintenance of the air intake and exhaust systems
and engine mounts, there isn’t a lot more
required. It’s best to change the oil and
filter when the engine is at full operating
temperature and to avoid operating the
engine for short periods and at low load.
Keep the oil, air, and fuel clean, and the
engine will provide many years of service.

Q. This will be our first season on the
water with our 2001 Regal 2760, set up
with two refrigerators and two batteries,
one house, one starter. I doubt if the one
house battery will last for our extended
weekends at the cove, running two refrigerators. Can I hook in another battery parallel with the house battery? Will this have
a negative result on the fridge units? How
about the OEM A/C onboard charger? This
is all Greek to me! — Ron Kinsey

A. Your concern about powering two
refrigerators for a weekend from one house
battery is well founded, unless the house
battery is a truly massive unit. However,
it’s not difficult to add a second battery
to the house bank. If possible, the two (or
more, you can use a number of batteries
in parallel) batteries should be of the same
size, type, and age. (Consider replacing the
existing house battery if it is more than a
couple of years old.) The batteries can be
connected in parallel — negative terminals
connected together, positive terminals connected together. A battery selector switch
can be used to allow use of one battery at a
time; however, if the fridge is the main load
on the battery, they can be used in parallel,
as a single battery. The AC-powered charger should be powered whenever possible.
Its output should be connected to charge
both sets of batteries. When choosing a
house battery, use the largest-size deep-cycle unit that will fit, a group 27, group
31, or, if you wish, a 4D.
