I need a wiring diagram for a generac 6551 model

Unfortunately, Generac does not provide wiring diagrams for their products. You will need to contact a local Generac dealer or service center for assistance.

Contact Generac directly to request the diagram.

Hi, you can try these sites, they have one for sale.

Your generator is equipped with a battery trickle
charger that is active when your unit is set up for
automatic operation. The trickle charger is
designed to help extend the life of your battery by
maintaining the battery when the unit is
not running.
you will need to review which circuit bord controls this and have that board replaced or serviced some of these gen heads have this built in and it will be the rectifier in the gen it self it will be a black 1x1x3/8 inch with a mounting hole in the center and 4 lug post for the wires replace this and your issue should be solved but consult your dealer for witch unit you have as to a control board external or the built in rectifier hope this helps.

The original part number your looking for is 78298 (Plastic tank valve). It has been superseded by part number 080270 and it it available here:
