Default Can anyone help me with an Aquamist system issue?

bought an HFS-3 system from Jeff Howerton in 2011 (S/N 10444) for my heavily modified 2007 STI. It worked perfectly for a long time. I don't drive my car often though. When I'm not using it, I usually fire it up once a month, let it get to operating temp, Check several things, among them that the HFS-3 is working then switch the car off and cover it again. A month ago the HFS didn't turned on. I thought it might be a minor problem and decided to check it afterwards. I did it this month. I checked fuses and connectors, measured voltage on proper pins, connection to ground, and swapped the gauge cable for a CAT6 cable to see if the cable was ok, but nothing happened. I also checked for voltage in all pins on the cable going to the gauge and none has voltage. I checked on the controller but nothing happens if the gauge is not working, so I have no clue what the problem could be. I'm out of basic troubleshooting ideas, and would love any suggestion to what might be happening. I barely use the system as I have different maps on my Accesstuner, and just use the high boost with the aquamist map when I'm up to no good (which is not very often).

I will appreciate any help to troubleshoot and fix it. Again, it worked one month, and the next didn't, without even driving the car. It seems like aquamist does not have a support department so I'm in the dark.

Thanks for the (hopefully) upcoming help!
