Test E

PINPOINT TEST E: THE CHARGING SYSTEM WARNING INDICATOR IS OFF WITH THE IGNITION SWITCH IN THE ON POSITION AND THE ENGINE OFF


Test E1:






Normal Operation
Under normal operation, the I (ignition) circuit 904 (LG/RD) will be 0 volts with the ignition switch in the ON position (C102a connected) and the engine not running. This will turn the charging system warning indicator on. This circuit is also used to turn the charging system warning indicator on if there is a fault in the charging system.
