:. Electric current ~ supplied a. tn
ignition system either from the genera
tor or batteries. The generator on
crates and delivers current onN when
the engine II running: the batteries can
reiiver current either when the eneln'
Il running of not. IN ordinary running
the generator supplies enough curren'

W. ttsrics well charged with electricity
4. The batteries need care and regu
lar attention.
,aD In coid weather water should b.
sdded about every II DAYS; In summer
shout every To- 10 days.
~ Only distilled water should h.
used: ordinary water NAV contain i'm
purities that are harmful 10 the battery

made NJ glass or rubber. Metal funnels
are conductors 81 ele'tricit, and are la.
lie 90 spoli the batteries.
tdD In cold weather special carr
should h. used to keen the battery
well charged and fun at distilled water.

:. The starter IL an electric motor
whi~h takes current from the batteries
and turns over the engine for starting.
When engine starts. the starter Is dis
snsnged from the engine automatically.
Releasing the starter button brings the

Handle spark piugs carefully.
A rack m the porcelain weahens the
