Tiffin Motorhomes 2017 Allegro Breeze Owner's Manual page 66

You can use an old toothbrush and a sparse amount of a diluted solution of baking soda (so-
dium bicarbonate) and water (distilled or de-ionized, preferred; tap water, acceptable) to clean
and neutralize any acidic build-up around the battery terminals. If this is done and there is any
foaming on the top of the battery, this indicates that acidic residues are being neutralized.
Rinse the cleaned areas thoroughly with distilled or de-ionized water (tap water is okay, too).
Avoid getting the baking-soda solution into the battery fill plugs to each battery cell; this would
drastically reduce the effectiveness of the battery (by neutralizing the sulfuric acid in the battery
cells) or, worse, "kill" the battery.
Dry the battery cables and terminals to prevent corrosion. To protect those terminals further,
use a plastic ignition spray on the terminals. Do not use grease on the terminals, especially on
the metal-to-metal connections, as grease may act as an insulator and keep the battery electrical
power from entering the cables.
If the Allegro Breeze is to be stored for an extended period of time, the 12 VDC battery system
should be disconnected. This will prevent unnecessary drain and corrosion of the batteries and
their terminals. The chassis disconnect switch, which is located in the panel directly above the
chassis batteries in the rear electrical compartment, should be turned off as well.
Over time, the batteries will lose some of the water used with the sulfuric acid in the batteries.
Following manufacturer's recommendations as found in the Owner's Information Package, peri-
odically check the fluid levels in all the cells of the batteries (be sure to use safety eyewear during
this process) and fill those that are low with water (distilled or de-ionized water is preferred; tap
water is okay). Don't overfill the cells; follow the filling directions exactly.
This battery checkup should be done on a regular basis to realize the fullest service possible from
the batteries over the longest time possible.
The house batteries are located beneath the entrance door step well. Access can be gained by
lifting the middle step tread.
NOT ICE
Disconnect the 120 VAC electrical power cord
and the negative terminal from the coach
batteries BEFORE working on the Allegro
Breeze electrical system.
ELECTRICAL FEATURES
If the Allegro Breeze ever requires any weld-
ing operations on the frame, first disconnect
the chassis batteries. Failure to do so will
destroy all of the chassis computer system.
