Question:
I have an approximately 4-5 year old Husqvarna zero-turn,RZ-5424, model # 965881301. It has ran like a champ since I bought it used. I've installed a new ignition switch, a new solenoid, and a new battery, but every time I try to start it (with the key), it blows the 20-amp fuse located under the seat. I can go across the solenoid terminals w/ a screwdriver, and it will turn over freely, and not blow the fuse. There is also a small (perhaps 14 gauge) wire that accompanies the large red wire to the battery, and I have BOTH of those hooked to one side of the solenoid. The other large red wire is from the other pole of the solenoid (2-pole, not counting the small yellow wire) that has a spade clip, connected in the center of the solenoid...to the starter. Just the large red wire to be clear, is connected to the starter alone, with no other wires coming FROM the solenoid TO the starter.
EVERYONE keeps telling me that I have a short somewhere, a naked wire somewhere, etc., but I've went over the thing a hundred times, and cannot find a single wire out of place. WHY can't I get it to start with the key, and WITHOUT blowing that 20-amp fuse?

Answer
Of course it doesn't blow the fuse as fuse is connected through the ignition switch and is between the battery + post and the the ignition switch. When you jump across the large terminal on the starter solenoid you are effectively connecting the battery + post directly to the starter bypassing the entire starter circuit.
Okay let try this since you probably don't even have DVMM or the circuit diagram. Unplug the ignition switch connector then remove the A1 terminal (purple wires), the S terminal (Yellow wire) and the L terminal (red-yellow wires) also disconnect the engine pigtail connector and then try the switch If it still blows the fuse then either you have the wrong or a defective switch. If not reconnect the S terminal, if it now blows during testing trace the Yellow (S terminal) for a short. .If doesn't blow the fuse reconnect the L terminal and again test again If it blows the fuse trace the red-yellow wire for a short. If fuse doesn't blow then reconnect the A1 terminal if it now blows the fuse during testing either there is a short between the A1 terminal and either the engine pigtail or the PTO switch. If doesn't blows reconnect the engine pigtail . Now if it bows the fuse then there is a short on the engine side of the pigtail. Can be as simple as you pinching the fuel solenoid wire behind the starter and the crankcase.
Hint your wife's bobbie pin is use the remove the wire terminals from the ignition switch connector housing.
