Only other thing to check would be to make sure the ground and battery cables are tight. Mechanic likely did this though.
six racer thanks we had the regulator replaced and all so far after a day, but he gave me the old regulator and the box of the new one, and the part numbers don't tally! basically the old one stamped F 00M 145 285 that cross refs with part number 12317523059 on the realoem site looks like it is for use with 120/140a alternators but correct me if i am wrong please anyone as I am not sure I am reading the realoem table correct

BUT the one he replaced it with is for use on a 150a alternator
Voltage regulator 150A 1 04/2002 part number 12317540656
