ARCO advises using a fully charged battery - A weak battery can damage the starter and starter solenoid. And to also clean all connections - A corroded connection creates resistance, lowering the amperage required for an efficient starting circuit. **Features:** - Dynamically tested and packaged for out-of-the-box performance - Nickel-coated and/or epoxy-painted to reduce corrosion  - Sealed to minimize water intrusion - Designed for long life and optimum performance - Armatures are tested to withstand 50 times operating voltages (12 volts) **Warranty Information:** When properly installed, all ARCO products are warrantied against defects in materials and workmanship for a period of 12 months for leisure use and 90 days for commercial or racing applications.  Add an extra year of warranty to your rotating electric ARCO product (Tilt/Trim Motors, Alternators, Outboard Starters, and Inboard Starters) when you register your product within 30 days of purchase.
