Connect the inverter using those "clamp" type connectors or
if your has actual permanent connectors, like eyelets, you can go ahead and
connect that first. Positive side to the + sign or red side of the battery and
Negative to the -- or black side of the battery. Now with nothing else
connected, make sure your inverter works by firing it up once. If you get signs
of it working, turn it back off and go to the next step.
Connect the float charger by using the eyelets that it comes with or by
attaching the clamps from it to the battery.
Red to positive, Black to negative... If you purchased a marine battery with
dual purpose terminals then connect the float charger to the wingnut set and
clamp the inverter to the pole (auto post) terminals.
