72 evinrude 9.5, Changed coils, point and condensers. Now I have no spark at all. Had weak spark before so I just replaced everything now I have no spark. It's gapped at .020. Coils are not rubbing. Clipped plug wires and gently twisted of them on. I did remove the ends of the kill switch from the button to the connector due to cracked and broken wires.

Did you clean the new points? They have to make perfect electric contact.

Do you have an ohmmeter? You should be able to see a couple of ohms difference in resistance to ground on the condenser side when the points open and close.

Which coils did you change? The exciter coils or the spark coils? Did you also change the condensers?

Like "tomhath" stated above, clean the face of the points to verify they are making perfect contact. Some times they get a surface film on them and don't connect with each portion like they are supposed to do.

Let us know how those ideas come out. And if you do have a meter, see if the points are actually making contact with the meter. That is a sure fired way to know. JMHO

********************
(Magneto & Driver Coil Alignment)
(J. Reeves)

To align the coils properly, have the metal vertical portion of the coil yokes aligned with the inside edge of the bevel that exists on the top portion of the aluminum seat upon which the coils sit. This creates the proper distance between the coils and the flywheel magnets. Faulty alignment creates friction and the yokes of the coils heat up, turn blue and expand.
********************
(Point Setting Of Magneto Models)
(J. Reeves)

Note that there are other ways to set points such as using a ohm meter or timing light... however, the following will result in a setting so close to being exact that one could not tell the difference.

Make sure that your feeler gauge is absolutely clean so as NOT to transfer oil/grease to the points.

Set the points as follows. Have the flywheel key aligned with the fiber rubbing portion of the ignition points. Adjust the gap so that a .020 gauge will pass thru but a .022 will not. Should there be any question of the points being dirty (touching the contact with your finger would cause them to be dirty), clean them with a small brush and acetone or lacquer thinner.

NOTE 1: Should the operating cam have a small portion on it with the word "SET" imprinted, align this portion with the fiber rubbing portion instead of the flywheel key.

NOTE 2: Should the cam have the word TOP embossed on the top of it, that is a cam that could be installed upside down and this is simply telling you which side is up. It is not a position where one would set the points.

Do you have spark now? You should unless you have the points grounded with those black wires that lead to the OFF/STOP button.
