1.-THE cause of trouble in the Ford
NJ. First of all We must know
he. the circuit of the current from
Pa,urcc. through the various units,
..ollis is al follow:
~, current is generated by tho
nie.to, which is bull, into the fly
pie, from which !, GOES 10 the mag
andlrrent collector plug, called tho
Berio contact. from there 20 the
Ineto terminal on the coil box.
Sos to the switch, then tho buss
Eby which IL is distributed 10 the
J, coils. From each OF the coils it
ncthroush the vibrator and then by
nare 10 the commutator. or timer.
Dthen through the metal OF the en-
vi and so back to the ma Encto.
Re high voltage secondary starts
ahe coil for each spav! plug. goes
uhe plug and returns through thc
,al OF the engine to the primary
r, attached TO the timer and so
lsush this wire back 10 the coil.
a the event of the engine failing
sstart. or stopping suddenly, be-
tse OF lack OF q, spark, we must
t determine which units in the sys-
i and which wires are common to
four cylinders, as IL the unit or
&c is connected to one cylinder only.
failure would only cause a miss in
Il particular cylinder. We find that
., the magnetic, the wire to tho mag

itch and the rotor of the commu-
:or are common to all the cylinders.
