Hi,

I’ve just been looking at the readings in greater detail and are as follows.

KEKO 29.6mA

Start-up from cold rises initially to 35.2mA

Then quickly falls in regular steps to about 12.4mA

Then as it approaches normal operating Temp. 10.9mA


If I open the throttle quickly it rises to approx 20mA and the return to about 10.9 -10.8mA.

The only worry I have is that when the engine is off – key out there is a current flow of 11.2mA for a few minutes and then it returns to 0.0mA.

It is as if there is a dc offset causing all my current measurements to be 11mA out.

I also check the fault codes on pin 14 (MAS controller although my model or 300ce 24v was not on the list.)

It listed fault 9 – Circuit 50 Failure. I have replaced this unit with a dealer supplied new one months earlier and the part number is newer.

Any more thoughts greatly received

Tony
