Hi John,

I am not familiar with the scope you are using and the scaling doesn’t seem to make sense to me but looking at the top it shows what I assume are min, max and current values? Working on those current figures, the voltage is low on the duty cycle, the ampage is too high and the duty cycle shown should result in a higher pressure signal voltage. It may be the way I am looking at it or the way you have the scope set. Maybe someone else would confirm for you what the typical figures for that particular system would be?
Was the capture taken under load, at idle etc?

I would also wonder about the peak on the last full event shown. It is mirrored on the fall of the next (half event shown) and would wonder how that developed in the following events. You have an increase in current half way through its rise which appears to be mirrored at the same point in its fall after its switched off. Its looks too uniform to be a glitch in the capture. It also appears to be linked to the point where you can clearly see the current limiting occur on previous events.
