My Husqvarna YTH2448 Modle # 96013000700 will not turn over with using the key but will turn over if I jump the starter relay with a screwdriver but still wont start,but if I spray just a squrit of starter fluid it will run a second. how can I fix it.

be sure your battery is fully charged. or put a new one in. try it now. if it still does it test the solenoid. check all grounds and connections. it takes time but it is an easy fix. there is a short somewhere. battery, connections., grounds, solenoid,. if you think it is the starter you can put a ground from the engine block to the ground on a good battery and a hot from the starter post to the hot on a good battery and it should try to start. but normally it is not the starter

Turn the key to the run position and then use a screwdriver to connect the two posts on the starter relay...will start the vehicle.

If you jumping direct to the starter and it is starting then the is okay and there is another problem in the circuit.

Need the other numbers on the id tag to look-up the wiring for further diagnosis.

turn on device and wait for response inspect every component for malfunction

check key switch first, and fuse.

I have a Husqvarna 2448 I just rebuilt the engine someone before changed the motor the four wires 2 go to charging like the other 2 go it discharges when you kick the pto in I put a new clutch on it the 4 wires are my problem

Im not sure what you mean by I jumped out the starter relay and the starter engaged.
so i am going to assume that you jumped from the battery side to the starter side on the relay and that engaged the starter... which is fine but you say the relay clicks when u turn the key. Pull off the clip on wire from the relay and push it against the battery side connection on the relay (u may need a small screwdriver to assist the connection) the relay should cause the starter to engage. If it just clicks (my bet) then you need to replace the relay (its really called a solenoid )

Charge battery to full, start in neutral, still clicks? Bad ground, or bad connection. Jump starter solenoid with screwdriver,etc. if motor turns over the relay is bad. Chaz Moto DC

There won't be any voltage going to the starter until the key is turned to 'start' with the brake locked down. And to check that, you need to disconnect the wire to the starter. I would first check the current going to the solenoid when the switch is turned to start by disconnecting the insulated wire going to the bottom of the solenoid and hooking a test light or voltmeter to it and turn key to start. Again the clutch/brake pedal has to be held/locked down. If there is power going to the solenoid but not to the starter, it's a bad solenoid. Hope I've explained this so you can understand. Dwain
