I have a cub cadet LT1045 (2007) and the engine won't start. It won't even crank. Just put in a new battery and I have lights but when turning the key all it does is make a whistle sound. All wiring visually is ok and oil is full. Have any ideas why it might not start?

This was put together by a few forum members and might help. Let us know how you are doing.
Electrical* problems can be very easy or very difficult, depending on four things.
1. * How well you understand basic electricity.
2. *What tools you have and know how to use.
3. *How well you follow directions.
4. *You don't overlook or assume anything and verify everything.
Remember we cannot see what you are doing. *You are our eyes, ears and fingers in solving this problem. *You must be as accurate as you can when you report back. *The two basic tools we will ask you to use are a test light and a multi-meter. *If you have an assistant when going through these tests it would be very helpful. *These steps work the best when done in order, so please don't jump around. *Now let's solve this problem.
First, check the fuse(s), check battery connections for corrosion (clean if necessary) and *voltage - above 12.5 volts should be good.*
Second, check for power from the battery to one of the large terminals on the solenoid. *One of the wires is connected directly to the battery and has power all the time so one of the large terminals should light a test light or show 12 volts on a meter at all times.*
Third, *check for power at the small terminal of the solenoid while depressing the clutch/brake pedal and holding the key in the start position (you may need an assistant to sit in the seat to override the safety switch). If your solenoid is a four wire solenoid, check both small wire terminals as one is ground and the other is power from the ignition switch. *If your solenoid is a three wire solenoid, make sure the solenoid body is not corroded where it bolts to the chassis of the mower as this is your ground path back to the battery. *If in doubt, remove the solenoid and clean the mounting area down to bare metal. *If there is no power to the small terminal then your problem is most likely a safety switch, ignition switch or in the wiring.*
Fourth, check for power on the other large terminal of the solenoid while holding the key in the start position (you may need an assistant to sit in the seat to override the safety switch).*
Fifth, check for power at the starter while holding the key in the start position (assistant again).*
Sixth, check your ground circuit back to the battery.
After you have gone through each of the above steps, let us know what happened when you did each step. *At that point we will have great info to tell you how to proceed. *Remember you are our eyes, ears, and fingers, so please be as accurate as possible.
Be as specific as possible with voltage readings as this will help diagnose your problem quicker. *If you do not know how to perform the above checks, just ask and I will try to guide you through it. *Youtube also has some videos and as you know a picture is worth a thousand words.

I did not have any power on either one of the small terminals, also no power on the other large terminal while turning the key switch.
There was also no power on the hot lead leading to the starter. I just replaced the solenoid on my mower, could it have gone out again? Also what could be causing the failure of the solenoid? It was running good and when i turned it off by the key it would not restart.

I have said this before. You need a wiring diagram to trouble shoot electrical problems. You follow this diagram like a road map till you find your dead-end road. Other then that you are just guessing.
Were you able to find a wiring diagram? I am looking for a wirning diagram for a model 1525. I found a wiring diagram for a 1045 on Google searcing for "electrical schematic 1525".
one of the google search returns listed pictures of various cub cadet schematic drawings. One of those drawings popped up a dialog box that said the diagram was for a 1045.
I was able to download a service manual from the Cub Cadet web site. That manual was for 1000/1500 Series Riding Tractors. THe manual did not have any electrical schematics. The manual listed step by step electrical trouble shooting items with pictures. the steps listed match what the 1045 schematic indicates.
Did replacing the PTO switch fig your problem?

Pages 84-86 are wiring diagrams. Look online at sears multimeters and go purchase an inexpensive one. Next print out wiring diagram and follow step by step instructions in troubleshooting section starting at page 71. Believe me, you'll be glad you did when you locate the problem, plus your multimeter will serve you well for years to come.
