John:

thank you for e-mailing the table.  i assume the
values would also apply to a 2-wheel drive, 2.1L '86
vanagon ?

in terms of procedure:

1. are you just using a VOM across the unit ground (if
so, what pin ?), or vehicle chassis ground ?

2. Pins 4 and 11 you seem to be measuring current
flow, is this correct ?

3. any precautions we should be alert to ?

Thank You Again for sharing you experience.
