Why does my room fuse keep blowing

Today my brother-in-law replaced the alternator in my 2000 Mazda 626. He informed me that the 100amp fuse under the hood blew. Now the radio won't work, or the interior lights, and the locks only work with the ignition on...AND NOW WHEN I TRY TO REPLACE THE ROOM FUSE, IT BLOWS BEFORE I GET IT ALL THE WAY IN...

SOURCE: blown 100amp fuse under hood.

you need to remove the sides of the holder, when you do you'll see a small bolt on each side of the fuse,, these fuses have legs that get bolted down, I believe its a 10mm head on it,, take care when removing them, they disapear quickly as they are so small, and keep track of which wires attached to them go on which side

They may not need to be replaced but they need to be repaired. Somewhere under there in that wire harness you have a power wire that has a bare spot chafed in the insulation. You'll have to unwrap that bundle, the one you jiggle, and check each wire carefully for a bare spot. Start with any wire that is red,pink, orange; those are the normal power wire colors, but don't stop if you find one. There could be more than one. Just tape over the bare spots, you don't necessarily need to replace them. If the wire harness has beeen rubbing on a piece of the car try to reposition it so this doesn't happen again. Zip ties work good for this. Hope this helps.

Where is the alternator fuse located on a 2002 mazda millenia

The alternator usses two fuses - a 100amp maxi fuse and a 30amp engine injector fuse. You should have battery power on both circuits at the alternator with the key on and the engine not running.

Fuse number 22 keeps blowing after friend jumpstart and blew 100amp fuse

Did he connect the cables wrong? I would have the alternator tested. I've seen bad alternators blow there fuses. If the cables were hooked up backwards, it may have damaged the alternator.

The alternator belt keeps breaking on a 2000 mazda 626 it has been replaced 4 times and all of the mechanics say they cannot find any prolbems no bearing prolbems no pulley misalligment

What they mean is there is no obvious problems. What else runs off that belt? Check for misalignment there. What makes it break? Does it happen after a long trip ( 2 hrs. highway driving) or at timed intervals ( every month, 6wks)?
Carefully check all the pulley's for sharp edges or bump outs into the belt. If you find anything use a small file and smooth them out. They can cut or pinch your belt and weaken it so it breaks over time.
Check the pulley alignment with the engine running where you can see all the pulleys and belts at the same time. This might mean crawling under the car. Vary the engine speed while you watch and take it up to cruising speed. You are looking for something to change, i.e a pulley to start wobbling. It could be a mounting bracket that bends at higher revs that needs to be replaced or strengthened.
Hope this helps.
