4 Glowplug battery
The power source for heating the glowplug may be
either a large heavy-duty 1.5volt dry cell, or preferably,
a 2-volt rechargeable lead-acid cell (accumulator).
1.5 volt heavy-duty or 2 volt rechargeable
dry battery lead-acid cell (at least 5Ah)
Warning (Very hot)
Never touch the nichrome wire while the battery is
connected.
Resistance coil
(nichrome wire)
Battery leads
Adjust applied voltage by changing the position of clip on
resistance coil until glowplug element is glowing bright red.
If a 2-volt cell is employed,
use a resistance wire, as
shown, to reduce applied
voltage, otherwise element
will overheat and burn out.
5 Battery leads
These are used to conduct current
from the battery to the glowplug.
Basically, two leads, with clips, are
required, but, for greater conve-
nience, twin leads with special glowplug connectors,
as shown on the right, are commercially available.
6 Fuel tank
For installation in the model, a 100cc(3.5oz.) for 15CV-
A, a 200cc(7oz.) for 25FX, a 240cc(8.5oz.) for 32SX
tank, is suggested.
7 Fuel bottle or pump
For filling the fuel tank, a simple,
polyethylene "squeeze" bottle, with
a suitable spout,is all that is
required. Alternatively, one of the
purpose-made manual or electric
fuel pumps may be used to transfer
fuel directly from your fuel
container to the fuel tank.
8 Electric starter and starter battery
An electric starter is recommended
for starting.
