Arthur,

I read carefully your last post - and admit I do not understand 100% of it (most, but not all). So I will just report the facts, because I think they are showing exactly what you were predicting (but I will leave that conclusion to you):

I was not able to achieve 12 volts state again last night (by which I mean - after your post to try the wires in the relay - I continued to get 5 volts at 85/86.

Tonight with cold car - always 85/86 - key on/engine on:

1. Without relay in - 12 volts

2. With NEW relay in - still 12 volts - but pump clutch NOT engaging

3. I watched meter while allowing engine to run. At approximately 90 seconds after car was running, the meter dropped to 5 volts.

BECAUSE clutch did not engage during #2, I decided to verify load circuit.

4. I put OLD relay in (still coverless) - manually closed relay contact - clutch engaged.

*****

You had told me to verify NEW relay rating - I verified - it is 12 volts.

*****

I will await your next instructions.

Thanks!

P.S. I worked 13 hours today in the sun at the Ford car show. Some guy here is showing a MB (circa '66 sedan body style - with a 450 HP Ford motor in it - very weird!)
