No spark at cyl 2 ( QD-22)

[Racex]

I have changed the condensor original type,set the points at 020".The wires are in good shape,But still can i not get a spark at cyl 2.The coil seems to be in good shape.Any ideas????

If I were to place a bet, I'd guess you have one of the following problems:<br />1 Bad coil<br />2 Bad condenser<br />3 Shorted plug wire<br />4 Points NOT adjusted on the high side of the cam<br /><br />Odds on favorite is #1 above. Swap coils and see if problem moves to cylinder #1.

Is it possible to check the coil with a OHM-meter to see if it is good or bad? Or in that case what are the readings with this test?

Yes, you can test the coil with a multimeter, but, your more than likely not going to get conclusive results. The coils primary and secondary windings may show OK when cold but the coil will fail when it gets hot. The primary winding should be in the range of .3-.4 ohms , the secondary, 3-7Kohms.<br />If the coil resistances look about right, the next thing to look at is the condenser. If it's leaking or shorted, you'll get no spark.<br /><br />The mag systems on these older motors are pretty much bullet-proof. They are easy to troubleshoot and the replacement parts are cheap. If you have the original coils, I'll almost guarantee they are bad. Hairline cracks in the outer shell are a dead givaway that they need replacing.

Both are the new epoxi-type

OK, fair enough. Was the cap you replaced OEM? Did you reference the coil to the two raised 'boss' marks on the advance plate? Does your motor have an extra wire (kill wire) mounted on the condensers going to a N.O. kill switch?? Perhaps the #2 kill wire is shorted to engine ground. Plug wires firmly inserted into coils? Plug wires of the solid stranded conductor variety (not carbon core)? Wire terminal ends and boots OK?? Points properly gapped and on the high side of the cam lobe. Did you swap the coils to see if the problem follows to #1? Is the flywheel key in good shape??<br /><br />Sorry for the rambling, I'm just thinking out loud.

Thanks for all reply,Will once again try all the methods.Otherwise i must buy another coil,In Sweden about $80,00!!!!! In US $14,93.

Yes, that is a bit pricy! That's why I mentioned to do the coil swap. If you get a spark on #1 after the swap, the coil is good. I would then start looking at the other parts on #2 to narrow down the problem.<br /><br />Good Luck, and post back with your findings. Your experiences can help others too!

Racex, if it comes to it, try the following places for the aftermarket coil (18-5181):<br /><br />infomar.be ($29 euros)<br />poortwatersport.nl ($27 euros)<br /><br />Perhaps it will work out to a savings for you. Some people order from the US and wait, as they find that less expensive sometimes.

HOUSTON!! WE GOT A SPARK.I checked everything and it was just the points that was rather burned just in the middle.I took sandpaper and now they look like new.Adjusted the clearence once more,And now there is a big fat spark on cyl 1 and cyl 2.Thanks for all the replys.<br /><br />"Old OMC:s never dies,They just go faster"<br />

<br />If the points burn again, then replace that set's condensor. But often burning is caused by contamination - clean the points well with acetone or alcohol.
