Got distracted checking the fuses in my 2006 Dodge Ram 3500 Diesel and now have an issue. The fuse diagram shows cavity 30 as a spare 15 amp fuse and cavity 31 as a 10 amp fuse for PCM/Transfer Case Brake. I have a 15 amp fuse and am concerned where it should go, cavity 30 or 31. Is it just a spare to be used if one of the other 15 amp fuses blows? All of the other spare cavities do not have fuses in them.

Should there be a fuse in cavity 31?

 

I see quite a few people have viewed my post but I have not got any replies yet. I am asking for someone to open their fuse box on a 2006 Dodge Ram 3500 Diesel and tell me what fuse, if any is in cavity 30 and cavity 31.
I would really appreciate the effort. Thanks

 

It would help if your post was in the correct place.

I will move it there for you now. For future reference:

I just went out and looked at my fuse box.

#30 is marked spare and has a 15 amp in it just like yours.
I have never had to change a fuse in my truck, so I can only assume that it is to replace a blown 15 Amp.

Hope this helps you.
