This is how to check a johnson and evinrude outboard coil plain and simplecheck the primary and the secondary wires for fire. You are testing resistance not amps or current.

Testing An Outboard Coil With A Multimeter Using An Ignition Coil From The Johnson H Or T

What most boaters do have is a digital multimeter.

How to test johnson outboard coil. A malfunctioning or dead power pack can cause your Johnson outboard to have problems at start up. When you talk about the coils you are talking about the primary and secondary ignition coils and you have to test both using the multimeter. You can use a multimeter to test the power pack.

58 rows JohnsonEvinrude DVA Peak reading and Resistance charts. You should have a reading of at least 150V or more. How to Check an Evinrude Stator Remove your negative battery cable.

How to check vintage Johnson Evinrude OMC outboard ignition coils to see if they are functioning. The secondary is not connected to the primary. The power pack on your Johnson outboard boat motor is a central part of the ignition system.

Power Pack Ignition Module for Johnson Evinrude Outboard A power pack or ignition module is the device that controls the timing of ignition functions on all engine cylinders. Secondary is about 9000 ohms 9 kohms. Most boaters dont have the equipment a professional has to test the coils on a Johnson outboard motor.

Using an ignition coil from the Johnson H or T Series. But i am not getting any ohms to show up on the white to purple. Remove the engine cover and locate your stator.

Take the good unit or a new coil and reconnect it to the engine bracket. You want to test the resistance not current or amps. Speed limiting operator warning function.

Testing an Outboard Coil and Points with a Multimeter. The key here will be to install the new coil so the gap between the magnets on the coil and the. How do you test a Johnson stator outboard.

I have a 2000 70 hp johnson motor and I think the timer base is bad. If the test described below tells you the ignition coil is bad its a simple matter to replace it with a new one by simply reversing the process by which you removed the old one. To test the secondary you need to measure across the two secondary terminals NOT from one high tension terminal to ground or primary.

Turn the dial on the face of the meter to OHMS not AC or DC voltage. Modern outboard coils consist of two windings around an iron core. And distributes this power to the ignition coils.

The secondary winding should have between 3000 ohms to 8000 ohms or 3 KOhms to 8 KOhms resistance. When working with the outboard motor you want to turn the dial to 200. Unlike other coils which fire one cylinder only this one fires two cylinders at the same time.

Some power packs also have a SLOW. Complete testing of a. I tested the timer also and the ohms reading is ok on the black to black white wire.

This means that there is no resistance the unit is burned out. Turn on the volt meter. Evinrude Johnson models after 1984 became pretty complex in that components changed yearly sometimes from model to model in the same.

Outboard ignition coils sometimes called coil packs supply the high voltage required to fire spark plugs. Connect the black lead of a ohm meter to the spark plug boot terminal then with the red ohm meter lead touch the ground of the coil or the powerhead itself if the coil is still installed. Using a digital multimeter youll be measuring resistance in ohms across the three coils that comprise the stator.

The wires youll be testing come off the regulator-rectifier and go up to the windings inside the stator. Plastic covered coils can develop cracks in the casing or cracks can develop in wire coverings which lets the current leak or arc out to the engine block. Multimeter testing of Johnson outboard coils.

An easy test and the FIRST test I run is to disconnect the stop circuit at the powerpack plug-in or screw. Im not getting any spark at all and the stator tested ok according to the cdi test procedure. Performing tests on ignition.

Ignition Coil for Johnson Evinrude Outboard. Weak spark and NO spark. You dont want to test your outboard coil with these wires connected.

Attach the ends of a multimeter to the coil connections for input and to ground testing electrical resistance in the unit. In order to properly test the coil you need to remove it. Then touch still with the red lead the orange wire if its attached to the coil.

For an outboard motor turn the meter dial to 200. Johnson_99_magnetohtm Johnson Evinrude OMC outboard motor outboard motor repair 99 15 hp dateyear of manufacture water pump. If your meter has one look at the screen.

Remove all the wires from the points so you are not getting any feedback from the condenser or driver coil. Set your multi-tester to the Resistance or Ohm setting. First in order to properly test the coil you need to remove it from the ignition plate.

Make sure it is set to OHMS not DC or AC voltage. The video below describes how to check vintage Johnson Evinrude OMC outboard ignition coils for functionality. The power pack supplies voltage to the ignition systems power coils.

Turn on your voltmeter. If an upside down horseshoe appears the meter is ready to read OHMS -- resistance. The video below describes how to check vintage Johnson Evinrude OMC outboard ignition coils for functionality.

Remove the cowling of the outboard to begin a static or resting test. So to review primary circuit resistance is measured between control module or points and ground and the secondary circuit is measured between the spark plug wire and ground. First in order to properly test the coil you need to remove it from the ignition plate.

If the readings are low disconnect the orange wires from the ignition coils and reconnect them to load resistors. While a bit lengthy here is a video posted by a guy who has been messing with antique outboards for years and he demonstrates for you where to make those connections in order to test. The secondary winding should have between 3000 ohms to.

Check the DVA output on the orange wires from the power pack while connected to the ignition coils. Replace the coil unit with a new one if the reading shows as infinity or zero. When low spark is detected on a plug it might be time to replace a coil.
