Evening y'all,so I've read the schematics,and I've read the pages on the differences between the 1 wire and 3 wire alternator,but none are for my year. I have a 1987 V1500 with a 4 wire shown below. I've wired the small red wire straight to the battery from the nut,wired the S voltage sense wire to the nut,and the key power to the brown wire leading back to the original harness. Both the F and P wires are unused. I have not tested the alternator itself at the parts store,but its supposed to have "low hours". While driving voltage doesn't exceed 11.8V regardless of RPMs. Did I wire it correctly? There is a fusible link in the same wire loom as the brown wire,and it sparks when I touch a hot lead,is it supposed to be wired to the alternator as well? Additionally,I cannot find the green power wire for the A/C compressor. Where on the firewall,or which loom would it most likely be? Thanks in advance for any input.
