Alternator Circuit Diagram Datasheet. Torque and locking agent fuel system. This pulls in the two contactors applying the power from the generator to the coach.
The purple wire is the 12. Diagram description there are a lot of ecu circuit diagrams documentation. Here is the schematic for the circuit.
It is a high voltage high current dual full bridge driver designed to accept standard ttl logic levels and drive inductive loads such as relays solenoids dc and stepping motors.
For example a relay can make a 5v dc battery circuit to switch a 230v ac mains circuit. Alternator 24v dc 70 amps with belt guard na cooling loop maximum pressure of 350 psi 1 diameter for fresh water. Phase a phase b and phase c. If 2 36v stm32g030f6p6tr stm32g030f6p6 stmicroelectronics.
