The first point to test is the capacitor itself. Enable precharge and measure of the change in voltage over the duration of the capacitor's charge. Note the time taken to fully charge the capacitors. It should follow the expected curve of voltage in an RC circuit. Now unpower the enable pin and measure the discharge. The times taken should be similar:
Precharge Precharge Discharge Discharge (Note: should be flipped as this is the charge graph)
