My alternator bracket keeps breaking cause of the motor Mount so the serpentine belt keeps breaking I just replaced the alternator bracket and the belt not even a week ago I was just driving down the road and everything started to dim and shut off. So I pulled over and it died couldn't start unless it was jumped and it only lasted maybe a half a mile. Does anyone know what is wrong?
Is this a good question?

If the belts aren't lining up properly and were dealing with the motor that has the mount on the end that runs between the belts your probably looking at a broken motor mount . When the rubber in the mount breaks the engine can torque sideways causing the belts to rub on the motor mount bracket and wreck the belt . to check the motor mount try using a jack and lift the engine . There should only be a little lift before you actually lift the car . If the motor moves up a lot you need to replace the mount. If the motor mount move to much then you can end up hitting the power steering bracket or the alt brace .

Can you post pictures of the broken mount? Maybe multiple angles? I'm not an expert on Honda Accords, but I am a mechanical engineer who works in the automotive industry. I was a mechanic until I graduated with my engineering degree. I only say this to show that I not only intend to help, but I am capable of helping as well. So if you really want to know why, it may be worth it to post the pics.
First guess is that something is misaligned. Pulley, bracket, alternator, etc.

This is strange for an alternator bracket to keep breaking, possible faulty belt tensioner/pulley putting too much strain on alternator, as Ford Fairlane/oldturkey03 suggest some pic's and more info. you are saying bracket breaks because of motor mount(is the motor mount moving a lot) replace it.

Hi, I'm just curious that @giondomenico says it "keeps breaking cause of the motor Mount". Unless there is something obviously wrong with it, why mention it and if there is why not fix it and see if the problem is resolved.

I have lost two top alternator brackets because the A/C compressor is locked up. When you activate to wind screen defogger the A/C goes on. Remove the A/C relay to see if this fixes the problem. I also think new mounting bolts might help. What torque does Honda call for? Blue Loctite helps as well.
