When relay 6 is energized its contacts 6a close and energize the D.C. closing coil 19 of relay 18 to close contact 18a to energize relay 7, thereby closing respectively contacts 7b to complete the batterymotor circuit, contacts 7a to energize the fuel solenoid 9 and contact 7c to maintain coil 19 energized during the starting period. Upon the engine starting and the alternator reaching normal voltage, relay 12 closes its contacts 12a and 12b, the latter energizing relay 14 which closes its contact 14b to connect the alternator to the load circuit, opens its contact 14a to isolate relay 6 from the load circuit, opens contact 14d to insert an economy resistance 10 in the full solenoid circuit, and closes contact 14c in parallel with contact 12b. Relay 16 is also energized over contact 15b which after a time delay closed its contact 16a to energize relay 15 which opens its contact 15a to disconnect from the battery the closing coil 19 of the stopping relay 18, opens contact 15b to disconnect relay 16 and closes contact 15c to maintain its coil energized. Whilst the alternator supplies current to the load relay 7 is maintained energized thereby permitting the starter motor to recharge the battery. Upon cessation of load relay 18 is de-energized, its contact 18a opens, thereby de-energizing relay 7 and causing its contacts to open and re-energize the fuel solenoid. In the event of the engine refusing to start or the alternator failing to build up to normal voltage, relay 13 energized over normally closed contacts 12a, closes contact 13a, after a time delay, to energize a trip relay 17 which opens contact 17a to disconnect the battery from relays 6 and 7, so that the set cannot be restarted until the relay 17 is manually reset. The closing coil 19 of relay 18 may be replaced by a rotary cam driven for example by a small electric motor.
