Spark Gap Tost
The entire ignition system can De checked
for misfire and weak spark using the
"Electra
Tester
If the ignition system will fire across a suf-
ficient gap, the entire ignition system oan be
considered good.
If not, proceed with individual component
'tests until the problem Is found
1. Warm-up engine thoroughly so that all
electrical components ave at operating
