Hi Neil,
I would definitely recommend the* "is the valve ball lifting by at least
1/32 inch when the solenoid is actuated?" method.".*... that is critical.
If you have the 390 p.s.i. and it operated once I would suggest adjusting
the solenoid CAREFULLY it is easy to cook the solenoid if you do it wrong.
