80LS1T Posted June 22, 2003 Share Posted June 22, 2003 Ok on my LT1 alternator all I have to have hooked up is the red thick wire, from the post on the back of it, then that goes to the battery...right? I dont have to have that other connect that plugs into the alternator hooked up right? Guy Quote Link to comment Share on other sites More sharing options...
Guest greimann Posted June 22, 2003 Share Posted June 22, 2003 The big red wire does go to the battery, but you WILL need at least one other wire to excite the field, and maybe another to run the charging idiot light. That should be covered in a Chevy wiring diagram. Quote Link to comment Share on other sites More sharing options...
80LS1T Posted June 22, 2003 Author Share Posted June 22, 2003 "Ah I see" said the blind man! I was just looking at the wiring diagram and now I see what I missed! Now I know why my battery kept going dead after 15 minutes of running! Thanks Greimann! Guy Quote Link to comment Share on other sites More sharing options...

80LS1T Posted June 23, 2003 Author Share Posted June 23, 2003 I forgot to hook up a positive ignition voltage to the field wire. Guy Quote Link to comment Share on other sites More sharing options...
