1985 Chevy Truck CAB

You put a new starter on? check there first for wires that are disconnected or in the wrong place. Also one of the wires may have burnt up. there are what's called fusible links on the wires. they are smaller wires connected to larger ones and they burn up it's like a giant fuse so the rest of the truck won't burn. the diagram i'm sending shows the layout, check by the accessory contact too it should be easy to find. Also the purple wire should be on the "S" side of the solenoiod.
