    Just wondering if this is that main fuse for the APU! see the pictures! My display wont turn on, and couple of guys here mentioned to check main fuse by the alternator! Some are saying that this fuse is on the batteries! So Just to make sure if somebody knows if I need to change this one on the picture!?Thanks!

    Not a Volvo expert, but there's a possibility that that fuse goes to an inverter, if not, then most likely your APU.
    I'd test it with a continuity tester first, before replacing it.

    He beat me to it! But follow the wires down. I think that may be the problem, That one side doesn't look very good... But what do I know. I hope you get it fixed.

    my apu has a fuse like that in the battery box, that joker is corroded for sure , clean it . a baking soda paste will work well. if the main line going to the batteries get corroded the apu wont start and will be dead, clean it and all other connections in there while you are at it.

    Thanks for the info guys!!!
    Do you know by chance where is the easiest place to get this kind of fuse? I noticed there is a thin white wire on the bottom of the APU, and its kind of exposed of isolation( is this the ground), but very hard to get to it.
