    Anybody know where I can find the fuse for the cigarette lighter of a 2010 389? Went to plug something in and it popped, the 12v and the fridge stopped working too. I'm wondering if it's got something to do with the other set of batteries that I got between the tank and the drives, since the fridge runs off of that aswell as the spare heater, but the heater still works.. I can't figure it out, any help is greatly appreciated.

    About 1:55 you'll see it. I put the video so you can familiarize yourself with all the panels. :)

    Cigarette lighters use to use a 30 amp fuse because they were exclusively for a cigarette lighter. Newer trucks are using 10 amp fuses because of wire lengths and these outlets are being used for other things like electronics. So look for a 10 amp fuse if not a 30 amp. There should be a diagram on the cover.

    I'm guessing you have more than one in the bunk? Are they all inoperable? If it's just the one, it probably isn't a fuse. You can remove the panel, unplug the cord from the back of the 12v outlet, and use a test light to see if you have current to there. If that's the case, then you have to replace the outlet itself.

    Yeah, I have a total of four, the other two work just fine, it's just the two that are where the a/c controls are

    Did you look at the bunk panel inside the passenger bunk door like the video says?

    Those might be on a separate fuse from the other two, then. Start off simple.. take a test light.. if you don't have a diagram for the fuse panel, just go through the fuses with a test light, and make sure you have power at both metal tabs on top of the fuses. If those all check out, then you'd go and check to see if it's the electrode itself.
