...or by disCharging a capacitor. The onset of complex control motors in vehicle systems demands a more responsive means of switching whilst, reducing where possible the current through the PCM. This method is referred to as pulse width modulation (PWM). By pulsing a circuit, the duty cycle...

...not over-Charging the technician thought. The technician who was very experienced in diagnostics, contacted me for advice on how to approach this issue, as they had not seen it before. As the vehicle was fitted with Stop Start and a battery monitoring module, we decided to scan all syst...
