SECTION X
ELECTRICAL SYSTEM
GENERAL - Fig. 23 and Fig. 24
The electrical system of the CH2000 is a 12 volt, direct current, single wire, negative
ground system. All electrical equipment is grounded to the metal structure of the airplane,
therefore the structure takes the place of the second wire. A 12 volt battery is incorporated
in the system to furnish power for starting and as a reserve power source in case of
alternator failure. The battery and alternator are both connected to the bus bar; from
which all the electrical equipment is powered, with the exception of the starter which
receives its power from the load side of the battery. The master switch, located on the
switch panel below the instruments, controls the battery relay. The master switch must be
on before any electrical equipment will operate. The CH2000 can be equipped with the
standard navigation lights, strobes, and dual landing lights located in the wing leading
edge.
TROUBLESHOOTING
Troubles peculiar to the CH2000 electrical system are listed in a Table at the end of this
section along with their probable causes and suggested remedies. Fig. 23 is a schematic of
the different electrical circuits used in this airplane and Fig. 24 shows the wiring.
After the trouble has been corrected, check the entire electrical system for security and
operation of its components.
ELECTRICAL POWER SUPPLY
The electrical power is supplied by one 12 volt battery and one 12 volt direct current
alternator. The alternator is located on the front lower right side of the engine and utilizes
a belt drive from the engine crankshaft. A voltage regulator is incorporated to prevent
overloading of the battery and electrical circuits.
