SeaLegs Repair - Go Up but not Down - Replace High Pressure Relay

My Sea Legs (2 years old) got to a point where they would go up but not down.
00:00 Introduction / Initial Diagnosis
01:32 Replacing the Trombetta
05:32 Apparent Success
06:50 Still Broken with new Trombetta
07:21 Play with Orange and Green Wires
09:00 Investigating the Pressure Switch
11:08 Bypassing the Pressure Switch
12:50 Investigating the High Pressure Relay
17:14 Replacing the High Pressure Relay
19:08 Summary and TL-DR
I contacted Sea Legs service but they were very busy so I decided to proceed on my own. I watched every video on the Sea Legs channel (Thank Nate!) and set to figuring out my particular problem. I initially suspected the Tombetta contactor and so I replaced it - which was not the fix. Then I started investigating the high pressure cutoff / alarm circuit and found my way to a broken Single Pole Double Throw (SPDT) 12V relay. I replace that relay (inexpensive part on Amazon) and my Sea Legs are once again working perfectly.
If you are in a hurry, jump to about 19:00 to see what was really wrong :)
Update: my neighbor had the same problem, I gave him one of the relays and it fixed his boat as well.
I put this video up in hopes of helping folks. I am not an expert and this is not official Sea Legs at all.
