No spark again 1969 85 hp

[sandhopper2]

Ok this thing is driving ne crazy
The other day I had great spark nice Blue and jumping , now nothing
The starter was draging and the Battery was not good , so Got new battery starter still draging
With the help from searching on here checked the wires using jumpers direct to the starter now spinng good
Then the no spark thing started .
On the blue wire from the power pack to the coil there is no voltage should this be 12 vdc with the key on ?
I don't want to buy the power pack , I will repower this project before I spend that much
Also saw on here that someone used a MSD unit to by past the power pack, might try that
What bugs me is I did hear it run only for a few seconds a few days ago and have not moved or disconnected any wires
I need to learn about this stuff as the dealers around me want $200 to check it out and then the repair charges if they can fix

Page 28 - Johnson Evinrude outboard ignition troubleshooter it looks like you crank motor and you should get 200 volts at the blue wire (dva).seeing as how you heard it run id be checking all wires closely.do the tests on the site as applys to your engine.

Don't go falling into that "It's always the Black Box" mentality. There are other things that can cause a no spark condition. For instance input voltage to the amplifier, breaker points, anti-reverse cut-out ring, coil problems, spark plug wire problems, and distributor problems. An orderly troubleshooting procedure is required. Trouble is not many people know how to do that.

Re: No spark again 1969 85 hp

you mean follow directions in a manual,bahhh!so true F R .the link I gave him will take him through a step by step procedure.numbers do not lie.

Re: No spark again 1969 85 hp

82rude. That was a good link you gave him. If he can't follow that, there's something wrong.

Re: No spark again 1969 85 hp

yah.stumbled across that place looking for a stator .have to admit much to my shame up until recently I was hopeless with a multimeter ,just didn't get it ,lol.thank god for youtube and how to use videos.

Re: No spark again 1969 85 hp

Not to be ashamed, you would be surprised at how many people don't understand those contraptions. You may be even more confused when I tell you that a DVA meter is not the same as an ordinary multimeter. An ordinary one can't respond fast enough to measure the very fast pulses of electricity that are found in those ignition systems.

Re: No spark again 1969 85 hp

That's why they made peak reading volt meters years ago before the DVA adapters. That's also when they made the Stevens AT-101 volt ohm meter. Life was good back then. LOL

Re: No spark again 1969 85 hp

Ok back trying to work on this 85 hp
I took the flywheel off to get to the coil wire , my question is how do you disconnect the coil and or the plug wires from here ?
Do they just pull out or do I have to take the stator off to get down more ?

Re: No spark again 1969 85 hp

To get the coil wire out of the distributor cap, you take the coil off of its mounting and then unscrew the coil wire out of the cap. The plug wires are the same. Don't start pulling or you'll have more problems.

Thanks for the reply
I will have more time to work on this latter this week
I think my issues is points , any idea where I can find them fro the 1969 85HP Rude ?

Re: No spark again 1969 85 hp

BRP has them part # 383655 for ONLY $65.00 each. I very rarely ever replaced them over the years and just cleaned them up good and reset them. Very low amperage goes through the points as they're just a trigger for the pack telling it when to fire.

(Voltage Drop To Battery Capacitance Discharge)
( Pulsepack When Electric Starter Is Engaged)
(J. Reeves)

On the older Battery Capacitance Discharge ignition systems (1968-1972), the electric starter reaches a point, even with a top notch battery, whereas the starter will draw excess voltage/current/whatever which results in a voltage drop to the pulsepack. The cure is to purchase a diode which is capable of handling 12 volts and installing it between the starter terminal of the starter solenoid (NOT the battery cable terminal) and the wiring terminal that supplies voltage to the pulsepack.

The diode must be installed so that the current flows from the starter terminal of the solenoid to the pulsepack... NOT vice versa. When that diode is installed in this manner, when the key is turned to the start position, the voltage that is applied to the starter is also applied directly to the pulsepack via the diode effectively eliminating the voltage drop and energizing the pulsepack with the required voltage needed for its proper operation.

----------------
Points on that model last forever unless you've applied 12 volts to them directly. Clean them with either acetone or lacquer thinner, then set them as follows.


(Point Setting Of Battery Capacitance Discharge)
( Ignition Models - 1968 thru 1972)
(Some have points - Some do not)
(Joe Reeves)

The points must be set to .010 but no wider than .010..... BUT in some instances due to a possible slight inaccurately machined crankshaft lobe or a slight offset of one set of points, a setting slightly less than .010 would be required as follows.

Whether the crankshaft has two or three lobes, when setting the points, check the setting of the points on each individual lobe by rotating the crankshaft by hand.

You may find that setting one set of points to .010 on one lobe, then turning the crankshaft to the next lobe, the gap measures .011 or .012 (too wide). This is where you would need to close that gap down to the required .010. A gap too wide can result in a ignition miss when throttle is applied.

Bottom line, pertaining to the point setting at the various lobe locations____ .010, .010, .009, is okay____ .010, .010, .011 is not!

Let us know what you find.

Re: No spark again 1969 85 hp

Thanks for all the help , Vacation starts Thursday and with a week off I hope to get this fixed
The wife has other ideas of what I need to work on , so maybe a couple hrs a day will get something done
Diode sound like a good thing to do , but I don't understand this a drawing for picture would help understand
Do I go to radio shack and tell them 12volt diode ? does it go inline on one of the starter leads ?
My battery is new , but the starter seems suspect shaft bushing has lots of slop

Re: No spark again 1969 85 hp

I have a bushing listed on eBay if you want it, part #305068.

You do need the diode obviously. Yes tell Radio Shack that you need a diode that can handle a automotive 12 volt battery.

Install it between the starter terminal of the starter solenoid (NOT the battery cable terminal) and the wiring terminal that supplies voltage to the pulsepack.

The diode must be installed so that the current flows from the starter terminal of the solenoid to the pulsepack... NOT vice versa.
