Look @ side plug. 12SI plug only take 2 wires & nothing but only grease/oil if lucky to keep "water" out of it. CS130 have space to take 4 wires in "water proof" plug. The opening post includes an image with what looks like the older style 12SI alternator. jelly2m8 JUL 11, 11:15 PM quote Originally posted by Patrick: What the heck is this mess?
