SO, I wired my panel with a cigarette lighter yesterday. Red wire got the juice and black was grounded to the airframe. The ground for the cigarette lighter terminted at the same place as the ground for the master, electric T&B instrument and one other item I cant recall as I type this. After install, I turned on the master and stuck a voltmeter on the cigarette lighter socket and it read 11 volts.
While I was at it, I wired up my WxWorx box. Red wire got the power and black was connected to a ground wire which terminated at a different place than the cigarette lighter. I then connected the GPS and the Wxworx box with the wxworx supplied connector.
Then, I inserted my GPS cigarette lighter power cord into the socket and flipped my master switch on.....My GPS made some crackling sounds from the speaker and would not power up. I unplugged the GPS and tried to turn it on my itself but to no avail...I think its dead.
How in the world did this happen? Did I wire something incorrectly?
