Please bear with as I'm new to the forum, but I've been trying to find a schematic on 1989 F150 ignition system. I HAVE the #%@ Chilton for this vehicle and it is crap. I need a wiring schematic for the complete ignition system for the 5.0. I had a burnt wire near the solenoid that seems to feed ignition coil and ignition module. Replaced wire all the way to firewall and still only have 4.7 volts to coil and ignition module. Changed out coil, ignition module, ignition switch, distributor, computer, and even ran jumper to hot side of coil. Coil still won't fire. Checked eec and fuel pump relays and they work and have 12 volts coming out of them. Need to know location of fusible links in detail and a complete ignition schematic including underhood and inside cab. Can someone Please help me out with this.
