Abstract
Various implementations disclosed herein include devices, systems, and methods for implementing a starter system that utilizes multiple starter solenoids physically isolated from each other. For example, the system may include a first solenoid mechanically connected to a starter motor. The first solenoid may be configured to receive a first starting current signal and mechanically couple the starter motor with an engine. The system may further include a second solenoid mounted within an explosion proof structure physically isolating the second solenoid from the first solenoid and the starter motor. The system may further include a non-incendive circuit mounted within the explosion proof structure. The non-incendive circuit may be configured to indicate that the starter motor is coupled with the engine and signal the second solenoid for activation to supply a cranking current signal to windings of the starter motor for operation.
