Sec.  393.30  Battery installation.

    Every storage battery on every vehicle, unless located in the engine 
compartment, shall be covered by a fixed part of the motor vehicle or 
protected by a removable cover or enclosure. Removable covers or 
enclosures shall be substantial and shall be securely latched or 
fastened. The storage battery compartment and adjacent metal parts which 
might corrode by reason of battery leakage shall be painted or coated 
with an acid-resisting paint or coating and shall have openings to 
provide ample battery ventilation and drainage. Wherever the cable to 
the starting motor passes through a metal compartment, the cable shall 
be protected against grounding by an acid and waterproof insulating 
bushing. Wherever a battery and a fuel tank are both placed under the 
driver's seat, they shall be partitioned from each other, and each 
compartment shall be provided with an independent cover, ventilation, 
and drainage.
