Description of Change: The continuous flow of electrical current to the coil in the electric starting motor will burn out the coil. After the engine has started, the relay in the circuit breaker panel gp prevents the continuous flow of electrical current. A new relay with increased capacity prevents damage to the coil. The new relay increases the reliability and durability of the electric starting motor gp.
Adaptable To: The new 259-5274 Magnetic Switch Gp replaces the former 125-1302 Magnetic Switch Gp in the circuit breaker panel gp for the models that are listed. The effectivity of the new relay is listed in Table 1.
Replace the former relay with the new relay if the coil for the electric starting motor fails. The installation of a new relay requires the installation of new harness assemblies. The new parts and the former parts are listed in Table 2. Use the information that follows in order to replace the former relay.
