How to test the RAVE valve solenoid .
You need a good set of crocodile clip leads , a good 12v battery .
I use these test leads they are excellent quality from an excellent seller also well priced .
Connect the positive to the horizontal terminal when held like this .
Then touch the other connector to the other terminal
the solenoid should snap closed fast and strong
if it does your solenoid is good .
See video below .
