Test the correct functioning of the points and establish the gap : lawnmower
- Connect a probe or alligator clip to the condenser.
- Connect the other probe to the rocker.
- Set your multimeter to the lowest resistance range.
- With the controls on the mower in the "on" position, and with the open points, the resistance must be less than one ohm and is effectively the resistance of the Magneto's primary coil and the cables of its serial meter.
- Now turn the crankshaft until the points are closed. The resistance should now fall to a lower value and is only the resistance of the wires. The point gap is set by releasing a screw and moving the capacitor, or by turning a screw. The gap should typically be 0.02 inches, but check the specifications for your engine to get a specific value.
- If you get a weak, thin, and not very blue spark, the capacitor (capacitor) may be defective. It is not possible to test this component without a special equipment, however, if you test it with a multimeter set to a low ohm range, a short capacitor will have a definite resistance. A good capacitor should give an open-circuit reading, i.e., usually an overload reading that is displayed as "1" on the display.
