Testing relay boards...., Can you bench test a 914 relay board....??? Options

[second wind]

Hello out there....my car has been dying after getting a good warm up but starts the next morning. The tell tale symptom is that the fuel pump does not run when the stall occurs and even after hours of cooling off it still does not start...but it does in the morning....???
So talk on the street is the relay board is too old to work properly.....the description of 914 LTD's improved and rebuilt relay boards matches the symptoms of my car perfectly so as soon as I scrap up the money I will buy one.....meanwhile I have two spare relay boards and one looks really good. Is there a way to bench test the relay board before I swap the boards ?? These cars sure keep you on your toes and a relay board with fresh soldered connections sure sounds appealing so Brad is holding one for me. So back to the swap out....I hate to go to the effort just to install another faulty board. Look forward and appreciate any and all comments and help....thank you very much!!!!

Well guys...thank you again very much and I have a new clue to share. What an automotive hell hole I have had today! So my Chevy S 10 pick up with almost 400,000 miles acts like there is no battery in the car. It has done this once or twice before....I tried charging the battery but the charger fell off the truck and didn't work after that. I figured I could jump it with the 914 but when I started it (first thing in the morning ice cold....but LA ice cold) it only ran 20 seconds and then no fuel pump sound. Hmmm, well I could take the battery out of the 914 and hook the truck up too it and that should work....not even close....barely lit up the dash even though it worked on the 914. So I am standing in the street with jumper cables in my hand and in two minutes I am up and running because of my new best friends that stopped to help me. So the new clue is that the fuel pump doesn't run even when cold.....just sharing. I think I will get the multi-meter out and start following some direction and start testing as an intelligent person....I will report back and I really do appreciate all of the help. BTW truck starts all day long now and might for a few days....but then ?? I am going to disconnect the battery at night and work on that issue later...914 in first spot.
All the best,
