Where is the plug for my on-board battery charger?

In most applications (unless otherwise specified by the customer), the plug for the charger can be located between the top of the pontoon and the bottom of the deck.

Depending on the brand of charger, the plug will either be coiled up and laying in the bracket on top of the pontoon, or it will be “plugged” into a holder. If it’s plugged into the holder, pull out the plug and then connect it to your extension cord.
