Always disconnect the battery when performing
resistance tests to avoid damaging the multimeter.

 1. Set the meter selector to the OHMS position.
 2. Connect the red tester lead to one spade end of the
    fuse; then connect the black tester lead to the other
    spade end.
 3. The meter must show less than 1 ohm resistance.                                                         AR603D

Primary Winding

 1. Connect the red tester lead to either terminal; then
    connect the black tester lead to the other terminal.
 2. The meter reading must be within specification.
Secondary Winding

 1. Remove the plug cap from the high tension lead;
    then connect the red tester lead to the high tension                                                    KC210B
