Fixed my alternator on friday and last night it started making a rattling noise from the alternator area but it was too dark to have a look, ive come out this morning and my car struggled to start and the rattling noise seems worse, i thought it sounded like the fan on the top of the alternator tbh but when searched on here cliokiz had a problem like this but not sure what the problem was or what he did to fix, any ideas??
