Question about 1991 Suzuki DR 350 S

1 Answer

I have a DR250s suzuki with no spark.

I need a test procedure to test the magneto & ignition module. A wiring diagram would be very helpful. I have no power at the coil.

    I have the same problem. When I turn on the ignition and kick start, I get one spark, then no more. I tried the coil on my scooter and I get repeated spark.
    I have power to the CDI box, and an AC signal coming from the pick-up coil. However I have 295ohms at the pick-up coil. I can't find a spec for this.

I have a 1996 gsxr 750 and its not getting fire but getting power everywhere else what should i check. ? Also witch wires on the coils are positive and negative??


Hi, Billy and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting, leaking, spark plug cable connections loose check for spark leakage in the dark.
6. Faulty ignition coil or CDI or electronic control module.
7. Faulty CKP, CMP, or BAS sensor.
8. Faulty ignition switch.
9. Tilt sensor needs a reset.
10. Security alarm failing to disarm needs reset

I have an L100 series John Deere tractor mower. Pretty sure the Magneto is not sparking. Need the diagram.q


A quick test is to unplug the small wire plugged onto the ignition module if it starts then it is good , you will need to plug it back in to shut it off when the key is in the off position.You will find the ignition module under the flywheel shroud, it has the spark plug wire on it. The wire runs through some safety switches on its way to the key and those switches are most likely the problem.

1991 Cutlass ceirra 3300 ,runs fine for short time. starts running rough,then dies/will not start again.changed fuel filter, then tested fuel pump.fuel pressure is good.what next ?


Check for spark when it won't start. If you have spark, might be your fuel pump relay, maybe the map sensor. If no spark, check another or all plug wires. If ignition isn't working, it could be Crankshaft Position sensor, Camshaft position sensor (or pick-up coil), ignition control module, coils, pcm, or the wiring associated with them. PCM determines spark timing after inputs from crank and can sensors, and sends ground signal to ignition module, cutting primary voltage to coils, initiating spark or high voltage from coil to sparkplug. All these parts have to be working right for ignition. All can be tested too. You'd need a digital volt ohm meter (DVOM) and a repair manual for your car with the test procedures. That Mitchell alldata-diy site has a special on subscriptions, pretty reasonable for a 1 month subscription, and excellent info and troubleshooting flow charts, wiring diagrams, etc.

Yamaha motorcycle xs 850 lh no spark


Hi, Brent and the usual suspects are:
1. Fouled spark plugs.
2. Discharged battery, needs to be 12.5 volts or better and be able to pass a "LOAD" test, your battery may show 12.5 volts but has little or zero amps and must be replaced.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting, leaking, spark plug cable connections loose check for spark leakage in the dark.
6. Faulty ignition coil or CDI or electronic control module.

Have a 5600 Gen. with 10 HP B/S engine OHV. Did great during Rita, replaced carb- changed gas-replaced plug- doesn't want to fire it seems. Where Can I find the magneto ? Are there points on the flywheel...


The magneto is by the flywheel. Depending on the age, there maybe points under the flywheel. If so you remove the flywheel and there the points are. Sometimes bugs build cacoons between points, make them inoperable. Newer engines have electronic ignition though. Follow the small wire from the magneto coil ( where the spark plug wire goes) it will either go under the flywheel through a plastic bushing, or to an electronic module. The magneto coils do fail you can test with an ohm meter. Before that test for spark. You can remove the spark plug, and let it rest on the engine to get ground, and turn the engine over. You always need 1-spark, 2 fuel . If you have spark, see if it will hit on starting fluid, if it does, then you have a carb or fuel filter issue. Those shut off valves on the bottom of those tanks, can be a problem

Need to know how to hard wire ignition module


Ford has substantially altered their 1978-86 electronic ignition test procedure. Due to the sensitive nature of the system and the complexity of the test procedures, it is recommended that you refer to your dealer if you suspect a problem in your 1978-86 electronic ignition system. The system can, of course, be tested by substituting known good components (module, stator, etc.)

This system, which at first appears to be extremely complicated, is actually quite simple to diagnose and repair. Diagnosis does, however, require the use of a voltmeter and an ohmmeter. You will also need several jumper wires with both blade ends and alligator clips.

The symptoms of a defective component within the solid state system are exactly the same as those you would encounter in a conventional system. Some of these symptoms are:
- Hard or no starting - Rough idle - Poor fuel economy - Engine misses while under load or while accelerating
If you suspect a problem in your ignition system, first perform a spark intensity test to pinpoint the problem. Using insulated pliers, hold the end of one of the spark plug leads about 1 / 2 inch; (12.7mm) away from the engine block or other good ground, and crank the engine. If you have a nice, fat spark, then your problem is not in the ignition system. If you have no spark or a very weak spark, then proceed to the following tests.

Tell if you are talking about this ignition system...

No spark on 1971 suzuki ts 125


Hi and welcome to FixYa,

Initially, check for pulsating voltage on the black/yellow wire from the magneto to the ignition coil. Additionally, temporarily disconnect the black/yellow wire to the ignition switch.

Perhaps a wiring diagram would be of additional help.

Good luck and thank you for asking FixYa.
