cTo remove any traces of dirt from contacts, insert strip of heavy paper dipped in alcohol and work it up and down between the points Repeat entire cleaning procedure for second set of pOintsdCheck points for good electrical contact, using ignition analyzer as described under "Breaker Point Testing" Check and adjust breaker point setting as necessary as described under ':Breaker Point Adjustment
eral information is given hereAll components of the ignition system should be checked, even though replacing part seems to have corrected the troubleFor example, replacing points may have increased spark, but further improvement might be realized if condenser is found to be weak and is replaced
COIL TESTING The coil is tested under conditions of actua operationas the ignition analyzer provides an interrupted primary current and measures the induced secondary voltageSee Coil Test Specifications, Section 2If the coil is in good condition and is suitable for use, the induced secondary voltage, as indicated on the meter, will fall within the green ("Good") areawith primary current adjusted as specified The coil must be removed from the armature plate for this testConnect the test leads from the ignition analyzer to the coil, making sure that the black lead is connected to the ground lead of the coil, the red lead to the coil breaker point lead, and the high tension lead to the coil secondary With the coil index adjusted as specifiednote the meter readingSee Figure 412
