Hi all

If somebody could please suggest a method to control the timing advance solenoid in my pump it’s running retarded by design

It’s a 12 v switched with a pwm wave input to control the advance

0 volt full advance and 12v full retarded

Volt meter says around 5 v at idle but I don’t have means to test the pwm wave

Would a resistor in-line lower the Volts to give slight increase in advance or a potentiometer ?

Any help greatly appreciated
