By the way this is exactly the problem I had with my 70 amp alternator. I replaced the battery and the popped field circuit breaker problem went away and never returned

Based on your last paragraph, it sounds like your single battery has lost capacity, it can't deliver the current needed by the pump motor causing an excess load on the alternator. Take tthe battery to an auto store and have a load test done on it.

All,
 
I and many others on the LML certainly appreciate the recommendations and advice that comes from this site.  Thank you!
 
My regulator is mounted under the glare shield and was produced after 2000 which makes it the most up-to-date for its model number.  It has not yet been tested.
 
Besides the many great suggestions from all of you, I have talked with Terry Norris Sr. from Aircarft Systems and Bill Bainbridge from B & C.  They also suggest that it may be corrosion or a loose connection in a crimped terminal or connector.  Also a devise if not already installed (it is, between the motor and relays) to prevent back EMF.  In the next couple of days I will go out to inspect, remove and clean as necessary the connnectors in the system.
 
Also a note of interest was that if I cross-tie my second battery when operating the gear, the field circuit breaker would not trip.  It only trips when operating on the single battery.  It is a two battery system and has operated on a single battery for years with no problem.
