john deere 318 won't start
Comments (12)Nope. just getting my info from an ONAN manual. This is a bit garbled since I'm copying it from a 2 column pdf file- 3. Pull spark plug wires off spark plugs and remove spark plugs. Connect an approved spark tester to each of the spark plug wiresand ground them away from spark plug hole. Turn key on and crank engine over for 5 seconds while watching for spark. If a spark occurs regularly, the problem is not in the ignition system. If no spark occurs, go to step 4. Incorrect wiring can cause elec- tronic ignition damage. Do not attach any lead or jumper with power (such as B+) to coil negative terminal. 4. Connect a jumper lead directly from the positive battery terminal to the positive (+) coil terminal (smaller diameter of the two threaded posts). Crank engine over while watching for spark. If spark occurs, the problem is in the low oil pressure cut out switch (if equipped) or related wiring, the lubricating system (low oil pressure), or in the other circuitry bringing voltage to the coil. If no spark occurs, go to step 5. 5. Connect positive side of voltmeter to negative (-) coil terminal (larger diameter of the two threaded posts) and negative side of voltmeter to engine ground. Turn key on and rotate flywheel slowly by hand while observing voltmeter. Voltage should switch between battery voltage and 1-1.5 for each revolution. If voltage does not switch properly, replace ignition module. 6. Install spark plugs and wires. If ignition module is being replaced, be sure to connect red lead from new ignition module to positive (+)terminal of coil, black lead from module to negative (-) terminal of coil. Continuity Test 1. Pull spark plug wires off spark plugs and remove spark plugs. 1-1 Accidentalstarting of the engine AWARNING can result in severe personal injury or death. Remove spark plugs before proceeding. 2. Turn ignition on. 3. Connect a voltmeter between the negative (-) coil terminal (larger diameter of the two threaded posts) and a good engine ground. 4. Rotate the flywheel slowly by hand in the clockwise direction until the voltmeter reading switches from approximately 1 volt to battery voltage. Atthis point, one of the chaff screen screws should lie between the two timing marks on the blower housing. To recheck timing, the flywheel must be rotated another complete revolution in the clockwise direction. Moving the flywheel back and forth across the reference timing mark will not activate the electronic ignition control.

Comments (25)lawnboy1022 It sounds like it may have jumped time. To check you can use an ohms meter and have some one attempt to turn flywheel very slow while connecting one lead to spark plug wire end the other to ground. Turn flywheel watching when the contact on flywheel comes to position with coil you should see meter move? Also pulling engine cover look close at key that aliens flywheel if it appears it spun even a little that should be the problem!...See MoreJohn Deere L120 Fuel Delivery problem? (Won't start)
Comments (2)Sounds like your not getting any power to the fuel pump, I would take the fuel hose from the fuel pump to the carb and disconnect it from the fuel pump and leave it connected to the carb then feel the hose full of gas and see if it runs....See MoreJohn Deere 180 won't start
Comments (12)I checked the solenoid on the carburetor by first verifying that there was power going to it when I turned on the key, then I removed it and held it up to a ground and energized it again. Nothing happened. I'm assuming that means the solenoid failed. Unless someone pipes in that I did't check this correctly, I'm going to order a new solenoid and report back after installing it. Thanks all... Jeff...See Moreapalmerjr
