HOW TO SERVICE A 14 KW GENERAC GENERATOR! FULL SERVICE!

Watch on YouTube

What happens here

Before beginning any work on the battery, ensure the generator's control panel is switched to the 'off' position to prevent any electrical hazards. Use an impact driver or a wrench to loosen the nuts on the battery terminals. First, disconnect the negative (black) lead, followed by the positive (red) lead. Carefully remove the old NAPA Legend 26R battery (rated at 540 cranking amps) from its compartment. Wipe down the battery compartment to remove any dirt or corrosion. Install the new EXIDE 26R battery into the compartment. Reconnect the battery leads, attaching the positive (red) lead first, then the negative (black) lead. Tighten the terminals firmly by hand, then use a wrench or impact driver for a final quarter turn, being careful not to overtighten and damage the terminals.

Goal: Remove the old battery and install a new one.
