Ok , I've changed out the motor on one of my F models . everything worked when it was parked. The new motor/used had a broken neutral safety switch wire which I fixed. I plugged everything in , installed a new battery and hit the starter button. There was a faint glow of the red oil light and then I blew a 15 a fuse, I replaced the fuse checked my connections and battery , nothing. No starter noises , no clicking , its in neutral . What's my problem. I've done lots of motor change outs over the years , I'm stumped.
