Well, two things.

First, to measure the EHA mA you have to put your meter in series with on of the leads. You can take the connector apart, remove the two leads, plug the front one onto the EHA pin and place one probe on the other pin of the EHA and the other probe on the remaining lead that did plug in to the EHA.

You can't measure it by simply putting the probes in the connector.

Does that make sense??

And be careful not to short anything out doing it that way (without the MB test leads).

Also, in my experience, that sears meter won't work when measuring the EHA current but I have another meter that does work. The sears meter does not seem to let the current pass through.
