fustrated no spark cant understand manual

[boatin]

My 1984 Evenrude 70 ran good last year.Stored it outside with a cover on it. I noticed some dirtdobber nests inside the engine cover. Probably has nothing to do with my problem. Im not getting a spark on any of the plugs. I have a manual and have checked the fuse and the switch circuit, kill switch etc. I cant imagine all three coils being bad. Is there an easy way to check the power pack? Clymer manual says I need a special meter. Im also confused about checking the charge coils. Thanks for this website.

Sounds like the Seloc is more your type of manual.

Seloc?? Plug is in; lying on powerhead.

Boatin, you are gonna have to start checking device resistance(stator, pickups, coils) as described in the manual. Then you will have a better idea of what it isn't.<br /><br />Just out of curiosity, did you remove the blk/yel wire and try it?

Re: fustrated no spark cant understand manual

I removed the blk.yel. wire at the ign. switch and checked circuit to make sure it wasnt grounded. Ill try resistance again on the charge coil. Maybe Im just having a bad day. Im even getting confused when checking each coil. Pulling the lead off plug #1 Im getting the same reading, no matter if I put the other meter lead on pin #A #B or #C.

Re: fustrated no spark cant understand manual

This is what is soooo fustrating!! Im beginning to doubt my abilty to make a simple resistance measurement. I have disconnected the plug wires to all three plugs. I put the black test lead on the # one ignition coil high tension terminal then I put the red test lead on terminal A of the ignition coil end of the disconnected terminal. I get a reading of 265 ohms. So far, so good. But I get the same reading if I move the red test lead to terminal B or even C. Keep in mind that I1m checking coil # one. Its as if all the terminals are shorted together!! Ever heard of terminals in a connector shorting together or have I gone nuts???

Re: fustrated no spark cant understand manual

If you have a voltmeter... you can check for voltage from the stator. Red to stator lead...black to ground. You should see around 3 volts. If you get a garbled voltage..ie..a whole wack of flashing numbers the Stator is not working properly.<br /><br />IMO I would change the powerpack.<br /><br />TMD

Re: fustrated no spark cant understand manual

Thanks abunch,<br />Ill try that and get back to you. I believe I did get a lot of different readings that kept flashing up.<br /> Thanks again

Re: fustrated no spark cant understand manual

Im using manual . When checking 4 pin connector coming from under flywheel Im getting an open circuit no matter which pins I probe. Now I guess Ill have to rig something up to pull the flywheel. trying I said Trying to save $$$$$$$$$

Re: fustrated no spark cant understand manual

Seloc is a different type of manual mostly working with tools from an ordinary toolbox,not specialized tools.It sort of talks you through the repairs you are making on your outboard.<br />Make sure the plug is in, is like a signature under my answers and has nothing to do with the subject matter.<br />I apologize if there was a misunderstanding.<br />Cornelis.

Cornelis,<br />Sounds like Seloc IS my type of manual. Purchased a puller for $11 and decided to pull the flywheel and have a look. If the coils looks bad I might take it to the shop and have them test it. They are nice guys/ probably wouldnt even charge me.Thanks. Every bit of info helps.

Re: fustrated no spark cant understand manual

The OMC flywheel puller costs over $50. Hope the one you bought for $11 works and doesn't damage your engine....
