Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Make and model? Do you have a voltmeter to test with? Dash and keyswitch gets voltage through the switch, from the posiitve side of the starter solenoid. The fuse may be bad, or the fuse holder may not be making the connection.
I need make and model. Check for voltage past the fuse to the keyswitch.
Check the power wire from battery cable connection. Be sure there is voltage past the fuse. 280-10 is fuse wire. I see snapper uses the battery connection instead of the solenoid end of same cable, See diagram above in the link.
