The main purpose of the starting system is to ensure rapid rotation of the crankshaft, which is necessary to start the engine. The starting system consists of a battery, a starter and connecting wiring.
When the ignition key is turned to the START position, the control circuit excites the solenoid valve, which, when triggered, supplies battery voltage to the electric motor. The battery supplies power to the electric motor, which When performing procedures involving exposure to elements of the starting system, the following safety requirements must be met.
- a) Long-term activation of the starter leads to its overheating and failure. The permissible duration of the starter activation is 15 seconds. After such activation, before the next attempt to start the engine, it is necessary to pause for two minutes.
- b) The starter is directly connected to the battery and if it fails, is overloaded or short circuited, a spark arc may form and cause a fire.
- c) Before performing procedures involving the elements of the starting system, it is necessary to disconnect the negative battery cable.
