mrk3cobra Posted October 4, 2017 Share Posted October 4, 2017 What gauge wire are being installed in LSX swaps, between the alternator and starter? Pete Quote Link to comment Share on other sites More sharing options...
Richard Oben Posted October 5, 2017 Share Posted October 5, 2017 Most alternator wires (charging) go to the battery or post from the alternator to the starter post from battery to alternator and are 10 gauge. This should not be confused with the starter wire which runs from the battery to the starter which is battery cable. HTH R Quote Link to comment Share on other sites More sharing options...
mrk3cobra Posted October 26, 2017 Author Share Posted October 26, 2017 I ran a #2 from the battery to the starter, and ran the same oem #4 wire from the alternator to the starter. I did add a 100 amp fuse inline with the cable between the alternator and starter. The oem wire had no fuse or fusible link. Quote Link to comment Share on other sites More sharing options...
alainburon Posted October 27, 2017 Share Posted October 27, 2017 I ran a #4 from the battery to the starter then a #4 from the battery to a distribution block. A #4 from the distribution block to the alternator. I used milspec wire for all that. Quote Link to comment Share on other sites More sharing options...
