What is plugged into port 27 in my helm junction box?
I've got a 2005 Sundancer 340 that is having helm control issues. Initially i thought it was the switch pads going out. One of them was recently replaced and I had assumed that the other may also be going out. My core issue is the 4 pin junction box by DNAGROUP under the helm. There are 3, 4 prong connections plugged into it. 2 of them are the touch switch pads and the 3rd is something else I haven't been able to trace. When everything is plugged in none of my switch pads work. When I unplugged the mystery 3rd 4 pin connection, my new port side switch pad powers on and works but the starboard switch pad is still dead. I've had two mechanics look at it and both are lost on what is going on. I assume its a bad ground, but I don't know this digital system well enough to sort out whats going on.
