be short circuited. The remedy is 10
wipe u dry and thoroughly clean. The
/ interrIpter points may not open or
may not make contact. This can be
seen by having some one slowly turn
I over the engine while you watch them.
When the roller Of the interrupter Is
against the hammer, or high spot Of
the cam. the points should be open
about l-50 Of an inch. or about the
thickness Of visiting card. The Illus
tration shows the position OF the cam
hen the points are open. When Of
the hammers OF the cam the points
must make contact
In time the interrupter points may
become burned or pittcd as 1t Is
termed This Will offer a resistance
20 the current and thus cause weak
euing Of the secondary. This may
be sufficient 10 cause a failure OF
the spark To remedy, get q double
faced thin hngernail file and insert
u between the two points and 30 file
them both al once. n filed separ-
atcly you may get them as shown In
Figure 3 which n anything, will be
worse than the pitted points.
When washing a car the hose
should never be played on il from the

the air cells OF the radiator and the
vent slots in tho side Of tho hood. and

Ignition units, cause trouble. When

not 10 use too much oil as by causing
q short circuit this may cause more
trouble than too little would. one
or two drops OF oil month Is usually
enough.
The wires are the cause Of more
ignition trouble than are the units in
the system. They may become loose.
broken or short clrcuitcd. The short
circuit may be due 60 the wire becom-
ing oil or water soaked. 70 the insu-

sometimes to the fact that the termi-

the insulation have come in contact
with the metal Of the engine.
Short Circnt.
Let me tell you what is meant hy
a short circuit. Suppose Il doctor or
derod YOU 10 walk around park for
exercise and suppose that instead of
going all the way around you took
q path through the park and thus got
home sooner. You would have taken
o short cat or short circuit and thus
not have done the work you were
ordered TO do In the same way If
you try to send current Of electricity
through a wire. Il switch, a coil, an
interrupter and then home instead Of
the current going through these units,
somewhere because of a bare wire,
/ etc, II gets back to the battery be-
fore 1t has, 1t viii have taken "A short
cut or short circuit. The remedy for
the short circuit Is to wrap the barred
wire in Insulating tape, or TO replace
the wire
Let us see where tho secondary
may give trouble. Like the primary
the coil may have been burned out,
|aud the wires have become loose or
short circuited Here, however, the
/ loose wire, because OF the great volt
Iagc, Is not so liable to cause trouble
as IT is in the primary, the danger oil

The distributor is the next unit ~
