Alternator failing
Hi guys,
I have a 2002 C320. I recently had some troubles with my alternator after putting new brakes in, did this myself. I think I did them wrong because the sensor was not showing I have new pads. A couple days after doing the brakes I got the Alternator/Battery visit shop and then came the battery undervoltage consumer defect display as well. I replaced my battery and than replaced my alternator. For awhile this worked and I did not have an issue until about a week ago when I applied the brakes at a stop light I received the Alternator/Battery visit workshop display again on my dashboard. It went away and came back only when I was applying the brakes just for that night. When I turned the car on the next morning it was there but then disappeared after driving for a couple minutes. Fast forward to yesterday and it has been on ever since. My question, can the brake sensor, if not positioned correctly underneath the brake pad, cause the alternator to fail? Should I check to see if there is a fuse that has blown? I will be taking the alternator out and back to the store I got it for an exchange but I am wondering if I should try taking the sensor completely out of the car, I do not really need this sensor as I can usually feel and hear when the brakes need changing. Any help would be great!

Would you be able to elaborate a little more on what could be going on than? I just think this is a little to obvious, brake pads put in wrong and now alternator is not charging, new battery and alternator and still malfunctioning but only started once I applied the brakes. Couldn't the brake pad sensor short circuit alternator when it is not properly put underneath the actual pad?

Okay, take the brake pad issue out of the equation and we are left with a failing alternator 2 times. What do you propose I replace next, how do I diagnose this failing alternator? I would rather not go to a mechanic shop as this would cost a lot more money than to just replace the part myself. I have changed both the battery and the alternator.
