4. With key switch in RUN position, continuity will
exist between switch terminals B to I. There
should no continuity between terminal S and any
other terminals.
5. With key switch in START, continuity will exist be-
tween terminals B to I and B to S.
6. Terminals are to make contact at angles shown
and to stay in contact condition as switch is ro-
