Battery Inspection and Care

As the batteries contain a significant amount of electrical energy, they must be handled with due diligence and
care. Some of the routine precautions include:
Remove rings, metal watchbands, and any other metal jewelry before working
around batteries. If any metallic object (tool, jewelry, etc.) contacts the positive
battery terminal or any connection made to that terminal AND also contacts the
negative terminal or any of its connections, a SEVERE ELECTRICAL SHORT will
occur which could result in an explosion, fire, and/or personal injury. Lead-acid
batteries contain diluted sulfuric acid which can be dangerous; avoid direct contact

Auxiliary Start Switch

The auxiliary start switch (Figure 7-2) is located on the driver's-side console box. This switch
briefly connects the Allegro coach batteries to the chassis batteries—this allows the chassis
batteries to "borrow" power from the coach batteries to assist in starting the engine. If the
chassis batteries cannot themselves start the engine in the "normal" mode, hold down the
battery boost switch and retry starting the engine.
By using the battery-boost switch while trying to start the Allegro engine, a jump-start
situation is realized between the coach and chassis batteries. If the battery-boost switch is
required to start the engine on a regular basis, ask your Tiffin Motorhomes Dealership to
check the chassis batteries and the associated charging system.
