Abstract
A starter solenoid for electric starting apparatus and its method of manufacture. The solenoid has hold-in and pull-in coils and a cap formed of insulating material that carries a start switch terminal and a motor terminal. Both terminals have axially extending internal bores and when the cap is moved into engagement with the case of the solenoid to secure it thereto end lead wires of the coils are inserted into the bores of the terminals. The terminals are radially crimped into engagement with the wires and the crimped portions are then welded to the wires. The ground connnection for one end of the hold-in coil is made by inserting an end lead wire of the hold-in coil into the bore of a hollow metallic terminal that is carried by a metallic plate member, crimping the terminal to the wire and then welding the crimped portion to the wire.
