This is on a 2015 GMC Canyon but is really a generic question. There is a plate with non-replaceable fuses on top of the battery (see photo below). I would suspect this unit is quite expensive and only available from GM in the near future. If one of these fuses pops the entire assembly would be replaced although I think I could modify it for replaceable fuses by cutting off the existing fuses and drilling a few holes. After supposedly identifying a short on a normal fused circuit I would typically just stick in a low amp spade fuse and see if it pops. At the anticipated cost of this assembly, however, I really need to use a non-destructive method. What approach would you electric guru's suggest?

These are standard bolt in fuses. Should be available at most auto parts outlets. Hope you never blow one of these large amperage fuses. You could have more problems then just a fuse!

You guys need to look at the picture more closely. These fuses only have a bolt connection at one end. The necked-down portion of the fuse is actually part of the plate. Yep, I've never seen this before either but if GMC is doing it, it must be the wave of the future. Even if I'm wrong, my original question is still valid and I wouldn't want to be blowing more of these fuses before verifying the problem has been identified and fixed!

These should be the fuses. Bussman AMI fuses

If the fuse blows use a test light....Hook the clip on the lead attached to the handle.. to the NEGATIVE battery terminal.Now touch the positive terminal. LIGHT = GOOD dark = either dead battery or bad test light or bad connection.Assuming light.Now touch each of the LOAD terminals on the battery.. one afte the otherLight good, Dark blown. Problem found (if that is it's the fuse).ANd wha't more.. No additional blown fuses.
