I have a 2005 Hunter 25. I didn't think it was going to be too difficult to install a small fan until I opened the 12 VDC panel.I have probed with a meter and could not find 12 volts anywhere, except from the battery. I would like to connect the fan to one of my accessory switches. Other than connecting directly to the battery with an inline fuse, can someone give me some help? Thanks, Barry
