Wade 10 Report post Posted October 21, 2010 I'm not planning this on my mustang but I have another 390 vehicle that I'm thinking about upgrading to a 3g alternator from a mid 90's Mustang. This way I can get rid of the external voltage regulator and add additional accessories such as an electric fan etc.. I believe the stock one is 61 amps and the 3g is 130 amps. Anyone do this and have some advice? How about the ammeter gauge, will it be affected? Thanks, Wade Quote Share this post Link to post Share on other sites
