Does il mako any difference what
candle power bulbs are used when wir-
ing up two lamps in series? II con-
nected in parallel would it make any
difference?.
The candle power OF a bulb does not
determine the line in which it shall
operate. Six volt lamps are made for
many different candle power, as are
lamps of other voltages, When wiring
lamps In series each lamp must nave
the same resistance as every other
lamp, whereas in parallel wiring lamps
Of various resistances may be placed
in the same circuit and each will take
current according to its resistance. IL
you were to take two six volt lamps
consuming ive-tenths amperes each
and place them in series in n six volt
line the lamps would burn dimly, be-
cause they would be operating at one
half their regular voltage.
When using a six cylinder engine,
three and one-half by five, two fifteen
candle power seven volt headlights
switched on full, one tail light and one
dash light, each four candle power,
three and one-half volt, what proper
ton Of the total current being drawn
from a storage battery is consumed for
ignition of the engine?
The ignition system does not a
very much current, the total amount
being measured in milliamperes. The
exact amount required depends upon

Is the amount of current consumed
for ignition constant. or do different
engine speeds or different road condi-
tions cause it to vary?
The current consumed varies slightly
because as the compression increases,
due to throttle opening, the resistance
to the current becomes greater. The
difference In current consumption at
200 II 900 r. p. m. would be exceed
ingly small and would require delicate
instruments for measurement.
10 there any preparation which can
be used to keep the water from coming
through q mohair top?
Boiled linseed oil rubbed into the
material is the best substance known
for waterproofing the top.
Ny engine misfires very badly and
hasn't any power to pull on any kline
Of q hill. had the carbon cleaned out,
tho carburetor leaned and magnetic re-
charged, but still it will misfire. What
is the cause of this trouble?
If the carburetor Is adjusted proper
ly and the magnetic timed and adjust
ed properly and, as you say, the motor
interior clean, the trouble may be
caused by poor valve timing, air leaks
around the inlet manifold, valve plugs,
etc, poor adjustments Of the spark
plug points. cracked spark plug insu-
latOrs or insulation breaks in the wir-
ing. If the misfiring comes from one
! cylinder all the time 1t Is caused by
faulty ignition or poor timing In that
cylinder, but If the misfring Is first in
one cylinder and then In another you
may look to carburetion. Test the cyl
inders by short circuiting the plug with
a hammer head. If you have deter
mined that the trouble Is local attend
to that cylinder only by removing the
spark plug, cleaning connections. With
the mistiring In no specific cylinder all
the time sea all joints which are leak
ing and readjust the carbureter. You
say you have removed the magnetic.
Has it been reset properly, and have
! the wires been connected correctly?
Sometimes, unknowingly, the operator
will place the No. l cylinder wire on
! M . ay1in1ar and misfiripo and hack-
firing will result.
Which has more power. a car with
thirty-four inch wheels or one with
thirty six inch wheels?
The larger wheels will consume less
power in mounting road Instructions.
The difference in the case you mention
would not be worth while considering.
Can you explain how oxygen gas gen.
orators are made. using range boilers?
The boilers are used not to generate the
oxygen, but to store 1t. The generator
usually is a small apparatus In which
the chemicals are heated, the oxygen
given off being transferred to a tank
from which it is taken for use in re-
moving carbon. etc.
II the front glass Of the dash lights
were half green or blue would it not as
sist approaching motorists, when lights
are dimmed, when running or at curb?
1t does not appear that the colored
dash lights would assist any more than
the regular clear glass type. In most
cities the use Of any other than clear
glass In the dash lights has been pro-
hibited.
