What I can't understand is why the SEF works with all other meters but not that internal one. Since the ID pins (a positive and a negative) come from the electronics in the control box and travel to the meter, there shouldn't be anything in the coil preventing it from working as it doesn't even travel into the coil. The only thing I can think of is from memory there were two grounds in the coil connector that the coils use and they are redundant, so maybe the SEF only uses one while all other coils use two. If the internal meter is using the ground pin that the SEF isn't using as the ground for the ID input then it might be not working because there is no ground present. That's if the meter is relying on that ground to be grounded by the internals of the coil.
