This on-off switch terminal is composed of electrical contact areas that connect to a charge or load on a battery. One is marked for positive current while the other is where the current returns to. These terminals can sometimes stop working or suffer corrosion which makes them dangerous to use. Brushing and cleaning a terminal can help remove dirt and debris, but a malfunctioning terminal requires a replacement. This is the case if the corrosion is severe enough to eat away at the metal or the terminal doesn’t clamp on the way that it should. The battery terminals can be removed and replaced using tools like pliers, a socket set, a wrench set, and a hacksaw. This terminal is a genuine OEM component directly from the manufacturer. It’s designed to be used on engines of snowblowers, lawnmowers, chipper shredders, and tillers. It is compatible with Tecumseh, Husqvarna, Toro, Troy-Bilt, Craftsman, Simplicity, Cub Cadet, Briggs & Stratton, and MTD equipment. Some items that can help with installation include anti-corrosion spray, felt pads, and heat-shrink tubing.
