Hello Jonathan
Thank you for the prompt reply, this is excellent information. I do have a couple of questions.
Q1: Should this be collected while the engine is running or with the engine off?
Q2: When you say b-lead I assume you mean with the alternator b-lead disconnected, so no current is going through the cable through the coil?
Q3: So how do I get to these pin voltages with the plug installed into the ACM, with or without the engine running?
I ask because there are some serious gymnastics involved with getting to the ACM behind my Glastar panel.
I'll look at it today.
Thank you.
Mike
