hey randy, need a part # for a voltage regulator for a 2002 V6 mustang coupe. also, will it work with a non-motorcraft alternator? i believe it was replaced with a Duralast? i have to check the brand after work, was bought from Autozone last year so most likely a duralast. thanks!

 

that is part of the whole instrument cluster, no servicable parts aval

 

so if my voltage regulator on my alternator is bad, my only choice is to replace the whole thing...again? yarrrr

 

sorry I mistook your post as meening for the volt regulator gauge, in the dash/cluster

now the volt regulator is ONLY serviced in the alt as an asbly from Ford, if you bought aftermarket, take it back as they usally have a free life-time-warranty.
now thats the catch/problem wth those aftermarket alt, they might be cheaper than the dealer but what good are they if you have to re-place them every year or so
what it is, is a ploy toget you back in the store to by other stuff as you wait and walk around, while getting you your "FREE" replacement alt, starter, water pump or.....
