Ok been having some stuff happen lately. Took the wifes van to a dealer for recall work and I drove my Jimmy and it saw me looking at a Subaru WRX. Well when I went to leave it wouldnt start. Found out I had the positive battery cable get a little hot and burn through. Replaced both with 2 guage cables and jumped it and then as I drove my lights and all other accessories got real dull. Ran a test and found the volts were dropping as the vehicle ran. If you jump it it starts at 12 volts and then after 5 minutes its down to 6 volts. Anyway I have heard about upgrading to a one wire alternator. What year chevy do I order it for?? On hookup I heard you run a jumper wire from the post to one of the plugs. Which one. Also the jimmy is a 350 with HEI, 4 barrel, auto if that helps. Thanks. Trying to build it to run with the big boys.
