I don't know if that is the proper terminology but I have two power points in my bunk that are no long working including thone I plug my cooler in to. What is the usual reason for this? I pulled one out to see if there was a fuse and couldn't find one. The plug itself was easy to remove, is it the plug that goes bad? The guy at the desk here at the TA didn't even recognize what it was when I showed him. :roll:

Its very possible that the plug has gone bad. My recently did...it got hot enough that the plastic of the nose of the plug started warping...and the contact tab inside the plug socket was pushed back in.... if that has happened, make sure you pull the fuse before trying to pry it back out...or use something non-conductive to do it with. If you replace the plug...make sure you have a minimum 7.5 Amp fuse....thats what my cooler requires, and the only add on plugs I found came with 2.5 Amp fuses. The fuse for the power point will be in your main fuse panel... most probably in the accessories area.

You might also want to see if you can dig around and check the wiring that goes to that power point....seems truck manufacturers have gone to using chintzy wire to do things.... Does the cooler work in another socket?

Cooler works fine, tried to plug in other things to the same socket, no go. Is the fuse in the plug? I saw nothing in the main fuse block that might be associated. All other plugs work fine so I'm thinking that each plug has its own fuse?

Ok, let me be clear on nomenclatures.

Socket= power point.

Plug= item inserted into power point.

If your cooler works fine when plugged into another socket....then it is a problem with the socket where it won't work. That problem could be related to a contact breakdown within the socket itself, a broken or fried wire between it and the fuse box.... or there is a fuse somewhere in line that has popped.

If you look into the socket....is there what appears to be a "tab" of metal in the center that looks like it is pushed flat against the back of the socket? If so, it needs to be gently pried forward a little ....otherwise it won't make contact with the plugs center "positive" point.

If your cooler does not work ok when plugged into another socket, and there is no fuse readily visible....then take the plug apart slowly and gently noticing how the parts come apart. Some of the plugs have an internal fuse that can be replaced.

I think thought that the problem is related to a blown fuse somewhere in line.... or that socket has just given up the ghost. Cooler plugs tend to generate heat and over time it can mess up a socket. That socket may have to be replaced....

Try looking under the bed and in the side compartments for a second fuse box. Many makes of trucks have the bunk fuses located there.

I have also seen the bunk fuses located behind the sleeper climate controls. This has only been on trucks that have a plate held on with a few screws. If the climate controls are part of the sleeper trim itself then don't worry about pulling it and looking behind it.
