No spark No.1 1970 Evin. 18hp

[Phillabaum]

Just completed a rebuild. Seals, gaskets top and bottom. Came with electronic ingnition. No. one cyl has no spark when testing with a timing light and pulling the start cord. swaped the ingnition modules with each other and still no spark on no. one. Swaped coils with each other and checked that continuity exists with the plug wires. Still no spark on no.one.
Now what?

Hi Phil. I believe the 1970 models still had the good ol' OMC "universal magneto". Did someone convert your motor to an electronic ignition system at some point? If so there's not telling what they did/didn't do in attempt to "improve" it. Here's a link on OMC ignition systems over the years as well as some other links that may help.

Thanks made for great reading.
I got the motor from my son whom just bought it with a boat. I did a complete rebuild and it came with the electronic conversion.
Since I know it is not the coils. Swapped both still no spark on number 1 cyl. and I swapped leads to the electronic servos and still no spark on number one cyl. I presume it is a short somewhere or the spark plug wire is bad? I do not know anything about the flywheel if that is a problem. REMEMBER I HAVE SPARK ALWAYS ON NUMBER 2 CYL.

Give me you thoughts.

Re: No spark No.1 1970 Evin. 18hp

do you know how the module switches the voltage between no.1 and no.2 cylinder?...can you pull the f/w and determine anything?...wondering if some circuit within the module has burned out or grounded internally and it isn't sending anything to the lower coil?

So much for the curse of "improvements".

Re: No spark No.1 1970 Evin. 18hp

I would un-improve it and put a proper set of points in it, with a tune-up kit including points and condensers being an even better option...

Me too. Less is more. Are you sure it's a 1970 model? I think they changed to electronic ignition around 1973ish. Maybe that's what you have. Just a guess.

Yes it is a 1970 all the numbers where there. I like the idea of going back to points and condesers. Yet it is not my motor and I don't want to put any more into it since I wount get paid back. (what we do for our kids). I have had the flywheel off several times to swap everything out with each other and the no spark remains on the number one cylinder. Its telling me it is a ground???? or maybe (since I know nothing about electronic ignition) it could be the distance from the flywheel to the coil??????? Just don't know. I guess I am going to remove the timing plate and inspect everything very close to look for a grounding issue. Since I am replacing the High lead to the spark plug and install new boot and clip for the spark plug. I enjoy working on it. The total rebuild was fun. Rings gaskets all new seals in the power head, exhaust housing, water pump kit and plate and rebuilt the gear box. New paint and looks like new.
Hopeing someone has had this problem before. I still have good weather here in central Alabama so I have time to use it.
Keep the ideas coming.

I probably can't help, but just to clarify... are you saying this is not an OMC ignition?
If not, can you tell who manufactured the conversion kit and/or model number?
Also, can you take a few pics of your setup? Thanks.

The CDI website has good ways to test the CDI units on the motor and you might want to look there for testing the system. Have you switched the wires from the switchbox to the coils to see if the miss moves to the other cyclender? The magnets on the flywheel should attrack a screwdriver from around a inch away. Are the magnets glued in or bolted and what shape are they in cracked or losse? Are the trigger coils testing good? Are the wires from the trigger to the switchbox in good shape, and not pinched, and braking down to ground? What shape is the stator ware ring in? Sorry for all the questions, but they all will cause trouble. JMO

No switchbox. What he has are two modules that replace the ignition points, likely MagnaTune as they are the most common kit.

Yep that is the set up. I think the name of the modules start with an "A" but not sure I am not in front of it now.
1. swaped the leads from each coil to each module. Still no spark on number 1.
2. swaped the coils for each cylinder. Still no spark on number 1.
Thus eliminated coils and the electriconic modules as a problem.
I ordered a high lead for the spark plug wire with a new clip. Although I did show continuity when checking the wire with an ohm meter.
Has to be a grounding problem or the coil for the number one cylinder is not getting energized by the flywheel. If the cylinder coil for cylinder number two works wouldnt that mean the magnets (which are the same are they not) work for the coil on number one cylinder.
I am still thinking a grounding problem with the the timing base or the wires leads from it to the modules. I have not swaped out the bracket that the coil connects to which would have been the points if they were installed.
Keep the ideas coming people we will work this out.

Re: No spark No.1 1970 Evin. 18hp

is there any difference in the f/w to module air gap between the no.1 module and the no. 2 module?

I did some searching, and it appears that Faztbullet has installed a number of these ignition kits. I would send him a PM.

I have an ATOM system. It would appear that the previous owner noticed the slop in the timing plate and replaced the points with the electronic ing. I have swapped everything back and forth yet still have the problem. From reading the attachement to the last email. It appears it takes some RPM to get fire sometimes. SO, I will go ahead and test run the motor and see if I get spark then. Wish me luck and thanks for the advice. I will let you know.
