The Yamaha Pilot Lamp Feed Back Cable is used with the GSCM-mini-y, GSCM-mini 60Hz or the GSCM-mini-i, when connecting to a Yamaha EF3000iS generator. The generator does not produce on AC output signal until the starter has disengaged. The GSCM-mini looks at the remote pilot lamp signal to know when the generator has started.
Cables are also available for Onan, Generac, Yamaha & Honda EU3000i Series. See Pilot Lamp Inverter Feed Back Cables.
