This one is a bit strange.
Both of the 12V outlet recepticles on the Jeep burnt out this weekend.
There are two. One is (supposed to be) 20A and is always live. The other is 15A and is only on with the ignition. I often use an air compressor after offroading trips.
Because I don't want to catch the wiring on fire, I have put a 15A fuse in the 20A fuse location - to make sure I don't overheat the wiring; the fuse will burn out before anything else gives up.
This weekend, I was inflating my tires and the 20A rated one stopped working. I thought I blew the fuse.
Checked and the fuse was fine. I probed the fuse socket and it was getting 12V. I started tracing wiring through the dash ... still no problem there. Probed the multimeter into the outlet and it was fine.
I used the other one (15A) and it did the same thing.
Pulled it apart and it turns out the center section of both plugs (positive) burnt out.
Why would both of these burn out in the same day ... without blowing the 15A fuse? If the factory says they are good for 15/20A, they shouldn't burn out.
Anyway, I am going to be converting the compressor to connect directly to the battery.
