Electrical problem
1990 Dodge Dynasty 6 cyl Front Wheel Drive Automatic

Have 1990 Dodge Dynasy that keeps blowing the Ignition system fuse in the under hood fuse box. Sometimes it blows right away sometimes it cranks for a few seconds and sometimes it will start and run for a few seconds but then just blows out the same fuse. I have disconnected the following.
Alt, AC,Ign coil,Cooling fans, both computers. Anyone have an idea? or a good wiring diagram?

Try to replace the ignition or trace all the wiring and look for any arch marks or touching wires. Something has to be grounding out if it keeps blowing the fuse. There has to be a serge of power in that specific line to cause the fuse to blow out like that.
