1974 25 HP Evinrude wont fire no spark at plugs against block. Coils check out. Now what ? How do I check coils, condenser, points and magneto? Is it complicated?

Motor is old but has very few hours on it. It has been sitting up for over ten years. I first tried spraying starter fluid in carb and starting it (Motor is pull start), motor wouldn't fire at all.I pulled out a plug and tested coil on pair of metal pliers I saw no spark from the 1st plug I tried. I did not test remaining plug for spark. How can I test coil? I hate to buy 2 and the problem be a magneto, stator plate or a set of points. Furthermore, how do I test the remaining electrical parts previously mentioned?

SOURCE: I have 1975 Evinrude 135 hp I cant get it to start

Have some turn the engine over and ground each spark plugwire to see if they spark. Good plugs won't matter without juice.

I have. A 1996 60 HP evinrude stalled out,put new plugs in it,no fire from plugs....and also what is the proper position of the fuel (red tab)

No fire to plugs. Replace the coil? Been a long time since I worked on these. I believe that they are set up like lawn mowers. They have a magneto to fire the coil. They can get rusty and not let the coil fire. Just something to check.

How can you test a magneto from a American indian moped

Nobody really calls them magnetos anymore, coil is the industry term, unless it has points and a condenser. If you are referring to the flywheel with the magnets inside of it, then that's called a flywheel, not a magneto anymore. You make sure by holding the bare coil lead with the rubber boot pulled back down the coil wire some, against the cylinder head, away from the spark plug, better yet, remove the spark plug, then do this. Disconnect any ground or shorting wires, and have an assistant pull the pullcord or press the starter button or turn the key. If you hold the lead about 1/8-1/4" from the cylinder head, you should see an arc of electricity jump from the lead to the head, just wear some gloves, preferably thick rubber, and don't touch any metal with that hand. The color should be pretty blue-ish otherwise the coil may be weak if it's say more of an orange spark than anything. If there is ANY spark, the magnets are ok but if it is not a vivid blue color, the coil is not producing a spark with a strong enough voltage to effectively run the machine correctly and will need to be replaced. Coils do go bad, just like plugs, but only after some time unless they're defective, then they'd fail prematurely usually pretty quick.

I have a lt1000 with a 17.5 horse briggs was running great died one afternoon and has no fire to the plug. keeps fouling the plug. what could be the problem.. How do u test the magnito and where does it...

you can use a neon bulb voltage tester to check for spark
a magneto gets its spark from the collapse of the magnetic field that occurs when the points close
the magneto is comprised of two coils.
a primary and a secondary.
when the points are open the primary and secondary are one continuous circuit and generates a considerable magnetic field when the magnet passes the magneto.
when the points close the primary coil is shorted to ground.
this causes a very rapid collapse of the magnetic field in the magneto.
this field collapse can generate a very high voltage surge (the power for the spark)
this surge can exceed 12,000 volts or more and yes it is a bit painful

What's mag

A mag or magneto is a coil of wire that is "excited" by a permanent magnet thereby inducing a high voltage to fire the spark plug with. Most single cylinder lawnmowers use mag and point systems to fire the plug. Coil is hard mounted and the permanent magnet is part of the flywheel with the points mounted under the flywheel.

A coil is a two coils of wire, one is connected to ground on one end and the other end is connected to either a set of points or an electronic switch, either of which turns on and off the current through that coil. When the coil discharges its electrical potential, its magnetic field collapses, inducing a high voltage in the other coil which is used to fire the spark plug.

1968 evinrude starflite 100 hp no spark

Some of those had a battery ignition with a short cap and rotor, and some had a magneto which reached down into the bucket. Both had points and condenser like an old car. The cog belt location was critical. 2 teeth off and it would not fire. the key switch was wired diferently for each ignition system.

Do you need a battery to start a 1972 250cc yamaha endero? ive check everything and it still wont run....

i am pretty sure that the enduro 250 gets the power for the spark direct from one of the magneto coils. there are 2 coils behind the magneto. one feeds the lighting and battery for the bike.
the other should run through a set of points, through the coil and then to the spark plug.
you should not need a battery at all to start the engine, but you may need to check the points and the coil, and the wires behind the magneto unit for any damage.

How does my 1939 evinrude work electric wise

Typically for small outboards.. that era and for many many years after.. use a Flywheel ignition System. a Magneto, Coil, Condenser and Points..

Most of those parts are located on the Magneto stator plate under the magneto "cap". Magnets rotate past the static coil.. hence stator..

The Magneto/Magnets rotate past the coil creating an electric current.. The condenser controls the volatage spikes or modulates the voltage directing the correct voltage to the spark plug. The Points open and close allowing the voltage when closed to travel to the spark plug at the proper time as in or during Compression Stroke / Power stroke.. Which is why timing is so important..

This is a very basic description.. proper operation depends on all parts being in good condition and the timing being set correctly.. good fuel and air supply.. not to forget a proper operating spark plug gapped correctly.

There are youtube videos (of course there is) on how to check the various components of early outboards..coil. condenser.. points etc..

Very simple system..performing a complex dance.

Hope this helps.

Best of luck

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

It wont start it has a light spark is it the coil

With a new spark plug set at .020", there should be a fat, snapping, blue spark with a magneto. Electronic systems require several good pulls in succession to generate good spark. Other than setting pole gap, there is not is not much you can do for electronic types except replace the whole unit. Magnetos have points and condenser to play with. The points are usually the prime problem with dirty/oily contacts or improper point gap (.020") at the high point of the cam. Coils are a more rare problem.
