The PCM controls the ground. It is pulsed (duty cycle) so you can't measure it with a VOM. If you have a dwell meter you can get a reading that way. At idle it should be about 70%.

What is the symptom you are trying to correct? The connections can fail, usually right at the plug. The most common failure is a sluggish solenoid.
