DIPLOMAT 2004
The chassis battery operates only chassis and engine functions. The
chassis battery is a crank type battery, producing the high amperage needed
to start the engine. Engine starters initially require a large amount of current
to crank an engine. Initial starter amperage draw exceeds 1200 amps. The
type of application in which the engine battery is used differs from the house
battery application. The engine battery state of charge remains consistent.
Maintenance is still required with an engine battery. Regular electrolyte level
checks and hydrometer readings should be performed. High electrolyte
consumption, or inconsistent hydrometer cell readings, may indicate a
charging system problem. Perform a charging system and current draw check
if the battery is exhibiting abnormal hydrometer readings.
NOTE: Replacement batteries should have the same cold
cranking amp (CCA) rating.
