L TERMINAL CIRCUIT (OPEN)
DescriptionINFOID:0000000009460663
The “L” terminal circuit controls the charge warning
lamp. The charge warning lamp turns ON when the igni-
tion switch is set to ON or START. When the generator is providing sufficient voltage with the engine running,
the charge warning lamp turns OFF. If the charge warn ing lamp illuminates with the engine running, a malfunc-
tion is indicated.
