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.
