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.


  • Dynamically tested and packaged for out-of-the-box performance
  • Nickel-coated and 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)
