Proto F14 Tomcat here.
Transistor at Q33 recently blew after coil locked on.
Now if power is turned on; the fuse highlighted in the reference picture shows continuity to ground at right side. I noticed continuity to ground on pins 1J11-4 and 1J11-5 also. These conditions are only with power on.
Replaced the coil associated, Q33 and its pre-driver.
Since these all tie back to U20...Im assuming the 7408 @ U20 is most likely bad.
Any thoughts? Thanks in advance
