    If they did any welding on the exhaust system there's a chance they fried the alternator If they didn't disconnect the battery before welding.

    When my alternator failed it did so on and off. A multimeter across the battery terminals will show you what's happening. My bet is it's about to die completely.

    Not necessarily.   Alternator failure can be sporadic and intermittent.  

    Like an organ in the body,  dysfunction usually comes before failure.
