I've often wondered if we could test the basic operation by putting a
voltmeter on the output and seeing what it was giving at idle, at a specific
low cruise, etc. and comparing that with the readings of one that works. I'd
think the voltages would either be way off or would be jumping around.
Unfortunately, I haven't found a good way of connecting to it.
