I messed up - now it wont start

[tnscmatt]

1973 lo boy 154. The generator was rebuilt and the voltage regualtor is 2 years old. The tractor ran great. The throttle cable was stuck so I replaced it. When putting the dash back together, it sparked. I know...I forgot to disconnect the battery. Now it wont turn over at all. The battery is fully charged. Did I blow out the voltage regulator?? What else could it be? I replaced the fuse. Dont yell at me.

Re-check your wiring connections where you did the replacement and see if they are still making good contact!----sounds like just a connection problem to me! thanks; sonny

Check all the safety interlocks.

The only safety interloc is the clutch pedal so it has to be depressed when starting.
Whats the fuse control?
