Freightliner Cascadia Cigarette Lighter Fuse

The layout says that the F18 A/B fuses are for the 12V cigarette lighter. Anybody knows what the A and B slots are for? Also, I was using a Koolatron cooler from the cigarette lighter and it not only blew the fuse, but also the 12V connector melted, blowing the fuse again. Now when I try to replace the blown fuse I get a spark from the board trying to insert the new fuse. any ideas on how to get this fixed and what the problem is?

The load is too large for that connection if it's melting the wires. How many amps does that cooler pull?

4 Amps, but nothing is connected to the cigarette lighter any more and still getting the sparks.

This is a job I would take to the shop then. Sparking and melting wires before sounds severe. Are all the other plug ins operating okay? Did you try plugging in the cooler in another location?

I got a new cooler and it works fine from the sleeper 12V socket.

Also the other 12V front socket works fine.

That could be the previous cooler as the culprit then. I have had that happen, and I've also had Cascadias with "temperamental" plugs.

Get it through a shop.
