Thanks for the info on the voltage regulator. I will fax this information to my mechanic. I do believe the relay for the pump has been replaced.
Looking forward to, and very appreciative of, any information offered.
My confidence is still high that I will get this car back on the road again.
However I may have to sell my W126 to do it!!
Not much of a market now on the West Coast for Grand Cherokees. Now that one is for sale
