I cleaned the points and distributor on the Allis Mag today, but still no spark, could someone please tell me how the kill switch should be wired up. This one goes from the coil, to the condensor and points via a switch on the outside of the mag, which just touches the metal of the mag.

Can anyone think of any other reasons why it is not sparking?

The HT leads are fine

James, The metal strip on the mag should not be touching the case unless you push it.The original switches were grounded internally and will have one terminal which is wired to the mag. If it has been replaced with a two terminal switch as some have you must ground one of the terminals and the other goes to the mag. The operation of the two terminal switch is reversed,"ON" will ground the mag. Remove the grounding wire from your mag and check for spark, If you still have no spark a trip to a mag shop is probably in order. Before you remove the mag, crank the motor until it impulses, remove the cover and note the position of the rotor so it can be reinstalled in the same position. If you have boys around like I do, hide the crank so the motor doesn't get turned while the mag is removed.

Are you sure that you have a magneto and not a battery ingition system? First replace the plug wires with copper core wires. Next make sure that the kill switch is working properly. remove the kill switch wire from the magento make sure that the kill tab of the mag is not touching any metal parts of the mag. Also make sure that the points, condensor, and coil are all good. Also make sure that none of the wires inside the cap are not touching any metal except where they are all held together with the little screw on the points. Does the tractor have eltric starter, or is it a hand crank start? I have had simalier problems myself. Also make sure that all the contact areas for the plug wires on the cap are clean and not coroaded, also make sure the inside of the cap is dry and clean no corresion on the contact areas.

That is the same as my B. The screw that connects the wire from the condenser to the points had been replaced some time before I got the tractor and was "just a bit" too long. It was touching the case and grounding out the points. A little work on the grinder and it was good to go, started on the first pull!
