DESCRIPTION:
John Deere 1842Gv & 1842Hv Sabre Yard Tractor Technical Manual
There is a diode in-line in the magneto kill wire coming from each ignition module. This diode prevents feedback from one module to the other. Without these diodes, one magneto could fire the coil for the other magneto. If a diode fails in one of the magneto kill wires, that coil, could be fired by the other module, the result may be similar to that of an erratic running engine. A twin cylinder engine may run adequately on one cylinder as long as the power required for the application does not exceed the power produced by the one cylinder.
