Pressure sender of the starting motor | |
The pressure sender monitors the air pressure of the starting motor. The pressure is monitored when battery power is supplied to the system and the circuit breaker is closed.
The resistance of the sender is varied in relation to the air pressure. A signal from the sender is read by the pressure indicator (starting air).
The table shows the comparison between pressure and resistance.
