Test the coil electrically
A digital multimeter is required for testing the resistance levels of the ignition coil. The terminals of the coil are going to be marked "negative" and "positive," and these are the two points where the resistance of primary winding can be measured. Step 1: Prepare the multimeter
To check a 12 volt coil, set the multimeter to at least a 200 Ohms setting. Attach both leads of the meter to the coil-terminals with black to the negative terminal and red to the positive one.
Step 2: Test the resistance
The normal, acceptable range for a standard 12-volt car is 1.5 to 1.7 Ohms. See if the reading is within this range.
Step 3: Test the secondary coil resistance
Set the meter to 20K Ohm setting, and attach the leads to the ignition coil's center terminal. The reading for secondary-coil resistance should be 11, because if it is lower

Why is my 97 Honda 4 wheeler not getting fire


There are three items that are connected together needed to create spark on your 1997 Honda 4-wheeler, regardless of which model it is.
Before we go through a checklist of these three important parts, look for a black wire with a white stripe that runs to the ignition switch and kill button from the CDI box. Disconnect this wire before it gets to the ignition switch and kill button, then check for spark. The most likely cause is a broken kill switch on the handlebar, or shorted ignition switch. Such a condition grounds this wire and kills the spark.
If this test did not restore the spark, continue reading...
Here is what is required to create a spark.

First, the alternator has one coil which generates a high voltage--about 125 Volts AC for the CDI ignitor box.

Second, there is a pulse voltage generated once every revolution of the engine that goes to the CDI box. This pulse causes the CDI to dump its stored energy from the 125 volt line into the primary of the ignition coil.

Third, If the two connections of the wire that runs from the CDI to the Coil are BOTH SHINY clean, the ignition coil will generate a spark.

If any one of these 3 don't happen, the spark will go away. Of these three, item 3 -- one or two tarnished and/or dirty connectors -- is the most likely cause. Just an added resistance of 0.3 Ohms or more in the CDI to Coil connections will cause the ignition to fail. No other wires have to be this clean.

How to fix an off and on switch on a briggs and straton model series, 19e400 5000 watt, on and off switch located on top of the motor. is there a wire thats supposed to hook onto the switch somehow.


Kill switch should have a wire connected to the tab on the spark coil under fan cover. The switch is a means of shorting kill wire to ground. On some generators, there will be another method of shutting down the engine. Usually on/off switch will be more visable on the control panel. Most likely the switch on fan cover was not connected to prevent confusion.

No spark 10 hp briggs+straton model 19E412-010701, ON/Off Switch broke replaced that, but get no spark


Remove the kill wire from the the back of the ignition module and test to see if you then have spark. If you have spark you would have a bad ground but if you still do not have spark then you may have a bad ignition module.

Won't start. No spark plenty of gas. Was running and just quit. Has there been a problem with any electrical on these? It has a briggs and Straton Motor.


This is going to sound way to over simplified but here goes. They have a low oil level sensor and when the oil gets low OR the sensor fails it kills the ignition. If the engine oil level is fine and you still have no spark.. disconnect ONE lead of the sensor and check spark again. If you have spark the Oil level Sensor is either very dirty or has failed.

My Coleman 6250W Gen. Has no spark . I got it fired up once and then nothing. I rebuilt and cleaned fuel system and I have plenty of gas. Does the Oil Sentinal prevent startup? Can I disconnect...


If it sat for 2 years, particularly in humid environment, try removing one of the wires on the back of the OFF / Shutdown switch. If you get spark then, the switch is defective. Also check the wiring closely as a pest may have been gnawing on the wire itself.

The oil alert will also cause the ignition to be disabled. Removing the wire from the sensor will temporarily defeat its intended purpose of shutting down the engine due to no / low oil. If the engine runs afterwards, then you may have a bad sensor if the crank case has adequate oil.

NO FIRE ON KOHLER 12.5 OHV MOTOR


All wires on a small engine except for the spark plug wire are to ground out the spark and stop the engine. Except a few for accessories and on generator/welders.

Knowing that, there is a small main wire that comes from your coil and leads to all other wires. It usually sits under your gas tank and runs toward your on/off switch or ignition switch. To see if it is any off your shutdowns gone bad, disconnect this wire. If still no spark then you either have a open in this wire or your magnito (coil) is bad.

If it starts, then unplug all the wires going to the kill wire and hook them up one by one until you find the one that kills the engine. Follow the wire to it's source looking for breaks in the line. If no breaks then the switch is out of place or bad.

Note: check your oil level first. Most engines come with a low oil sensor that will kill the spark if the oil level gets too low.

To check is your magnito is bad or you have a short, disconnect the wire at the magnito found by the flywheel under the flywheel cover. Tuck this wire out of the way and try to start your unit. No spark then you have a bad magnito.

I have a potable generator that will not turn off.it's a 16.5 briggs vanguard v-twin motor.i replaced the coils and the diode wiring assembly.i fill the diode assembly might be backwards.is that possible?


Are you saying the engine will not turn off? The engine shut down uses a ground on the ignition circuit to shut down. This kills the circuit that provides the spark for the engine to run. See if you can trace the circuit for the shut down and check the ground connection.

Powermate 6250 no spark


Hi Mark,

The engines used on the Powermates have a low oil shutdown system that can be troublesome. Try this:

1 - Make sure there is enough oil in the crankcase. The oli level needs to be all the way up to the bottom of the threads in the oil fill hole.

2 - Still no spark? Replace the spark plug with a new one (properly gapped), then spray something like brake cleaner into the carb. Pull the rope and see if you hear any detonations from the engine. If the engine tries to start but won't you need to look at the fuel system, then the ignition.

3 - If you proved there isn't any spark happening, look under the plastic cover where the kill switch is located. You'll find a small metal box with wires coming out of it. Find the wire that goes from the box to the kill switch and disconnect it at the switch. Mark things as needed so that you'll remember where to put them back. Give the rope a gentle pull and see if we have a working ignition, if it does have spark there is something wrong in the low oil shutdown mechanism.

4 - If you've convinced yourself that the low oil shutdown is misbehaving try changing this oil and flushing out the crankcase. Look for any evidence of debris that would have made the oil level float bind. As a final test reconnect the wire we took off the switch and disconnect the one that goes from the module to the oil sensor on the side of the engine, if you don't get a spark with the sonsor disconnected you probably have a bad module.

5 - If we didn't get ignition with the low oil shutdown disconnected from the kill switch, reconnect the wire we took off and then disconnect the (usually black) wire that leads down inside the engine. This is the kill wire for the ignition module. If you get the engine to start with this wore disconnected you may have a shorted kill switch, test it with an ohm meter.

6 - if there still isn't a spark with the kill wire disconnected you may have a bad ignition module. You have to take off the carb, then the blower housing to get to it. Check that the kill wire isn't shorted to the block anywhere, and that the module has the proper gap and orientation before replacing it, The modules say "cyl side" on the side that should face into the engine. A regular business card or a playing card ought to just fit between the magnet on the flywheel and the module, too loose would cause a loss of ignition. You get extra points if you use a feeler guage to set the gap to 0.010 inches.

7 - Ignition modules are available from a bunch of different places, your local Briggs supplier will want to know the model, type, and code numbers located on the side of the valve cover in order to be sure which parts you need,
