BATTERY

The battery is a 12-volt direct current source connected in a negative ground system. The battery case is sealed and includes 2 vent holes to release gases. The battery has 3 major functions:
- engine cranking power source
- voltage stabilizer for the electrical system
- temporary power when electrical loads exceed the generator output current

Battery Positive Output (B+) Terminal Circuit 38 (BK/OG) (2.3L)
The generator output voltage is supplied through the battery positive output (B+) terminal circuit 38 (BK/OG) on the rear of the generator to the battery and electrical system.

Battery Positive Output (B+) Terminal Circuit 36 (YE/WH) (3.0L)
The generator output voltage is supplied through the battery positive output (B+) terminal circuit 36 (YE/WH) on the rear of the generator to the battery and electrical system.

A Circuit 112 (BK/YE)
This is the A terminal battery voltage sense circuit and it is used to sense battery voltage.

Circuit 921 (GY/OG)
The generator monitor (GEN MON) circuit communicates the generator load and error conditions to the powertrain control module (PCM).

Circuit 920 (BN/WH)
This is the generator communication (GEN COM) circuit. The PCM determines the optimal voltage setpoint for the charging system and communicates this information to the voltage regulator through the GEN COM circuit.
