It is not a difficlut job at all once you locate the solenoid. There are two large wires going to the side posts and one or two smaller wires going to the smaller posts. Just keep track of where these were originally and put them back in the same place o the new one. The solenoid is held on by two small bolts or screws.
I assume you are talking about the starter solenoid: Follow the positive battery cable from the battery - the other end will be connected to the starter solenoid.
Look for loose connections at the battery, starter solenoid, starter and switch. If all connections are good, the starter solenoid probably needs to be replaced.
replace battery & starter solenoid.. possibly carb.
There is normally a second starter-position solenoid under the clutch pedal. It probably is not getting contacted when you step on the pedal.
Like any power switch you have Power in, Ground, Switched Power out and the Switch Terminal.
I assume you mean a starter solenoid. Look at how the old one is hooked up. Put the new one in that way. ...and disconnect the battery first.
Contact Sears or check their web site.
Look for a loose or corroded battery cable. If the cables are ok at the battery, check the connection at the starter and at the starter solenoid. Otherwise, the solenoid may need to be replaced.
Depending on what model mower you have, there could be several problems. But, start by checking the fuse. Most mowers have a fuse that is located near the starter solenoid.
If it is a riding mower it may have a blown fuse. They are usually located near the solenoid.
battery, solenoid, starter, engines locked up from overheating, or a bad switch (IE seat brake deck blade engagement swithces)
Sounds like a bad ignition switch. It could also be a bad starter solenoid. If you can find the solenoid you can unplug one of the small wires while it is trying to crank over and see if it stops. If it does it is probably the switch. If it doesn't then it is probably the solenoid.
