Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello. Thank you for choosing Just Answer. I will be happy to assist you. How long did the replacement solenoid last, before it failed?
Thanks for this information. Your solenoid have a large red cable attached to each of your solenoid posts. How many small wires are attached to your solenoid?
Do you have a 12 volt test light, or a multimeter?
One of your small wires is a ground, and the other is a hot wire from your ignition switch, when you turn your key to start position.
We need to determine if the wire is energized, and has voltage when your key is in start position.
Can you get me the model numbers off your mower? I will check for a wiring diagram.
I did not find a wiring diagram. Which tester do you have, test light, or multimeter?
Ok, without a wiring diagram, I am not sure which wire is ground, and which one is your energizing wire. We will figure it out.
What colors are the two wires?
Ok, green is likely ground, and orange is likely the wire that should have voltage in start position. Are you familiar with using jumper wires?
I am trying to determine if your solenoid is actually bad, or if you have a loss of voltage to your solenoid.
Did you use a screwdriver to jump your solenoid?
Let's try something. Instead of using your screwdriver to jump across your two large red solenoid cables, jump from hot post on your solenoid, to the terminal where your orange wire attaches to your solenoid.
Let's see if your engine will spin.
Thank you for checking. Use your meter to check for voltage on your orange wire. When checking, make sure your parking brake is locked, and your ignition switch is in start position. You should get a reading of 12 volts.
If you are not getting a voltage reading, this is part of our problem. Are you getting a good ground on your black probe on your meter?
Test your meter on your battery, to see if you get a reading ...
Have you checked for a blown fuse?
The reason I asked, is because you are getting a voltage reading at your battery, but not on your orange wire.
The wiring connector that attaches to your ignition switch has a red wire in it. Check to see if you have voltage on your red wire in your wiring connector.
Thanks for checking. Do you have a piece of wire you can use to jumper across your red wire and your orange wire, in your wiring connector?
Is the other end of your orange wire still attached to your solenoid?
Keep in mind that your orange wire must have voltage, and your green wire had to be grounded.
Put your jumper wire back into your wiring connector, Red Wire, to Orange Wire, then check to see if you are getting voltage on the opposite end of your orange wire, at your solenoid terminal.
No problem. Dinner is an excellent reason to stop.
Absolutely. I will get an alert to notify me that you have returned.
You are very welcome! You can wait until we are finished, before you leave a rating.
