MOUNTING l

The chassis contains the complete radio, power supply and speaker. This unit may be mounted
in any convenient location on the bulkhead of the car. li possible it Should be mounted on the
left side or close to the Center. This makes for an easier installation. This installation is'rnade by
drilling only one 5/16 inch hole in the bulkhead, Care must be taken to see that the mounting
bolts on this unit as Well as all others, such as the antenna and generator condenser, forrn a
good ground connection, This can be accomplished by scraping the paint from the spot under
f the mounting nut and Washer.

FIGURE 1

Install flexible cables in the proper place (see figure l). The other end oi cables go to the controls
7l6-Tl and 7UOfV2. These are installed in the panel kit (see instructions iurnished With panel kit).
The "A" lead of the radio connects to power socket on control 7UO-VZ.

Antenna lead is plugged into the antenna socket (see figure l).

After installation, tune in a weak station around 1400 KCv and adjust antenna trimmer for maxi`

mum Volume. DO NOT ADIUST OTHER TRIMMERS.

FIGURE 2

Remove the coilfto~distributor highftension lead from the distributor. Cut the lead two inches from
the end, and screw the distributor resistor onto the coil lead. Then screw the short length into
the resistor, and plug the cable into the distributor cap,

One noise-filter condenser is furnished, Condenser must be connected to the output terminal of
the generator (never to the field terminal). The generator-condenser bracket should be fastened
to the generator housing, under the screw that holds the field.

ln some particularly stubborn cases of motor interference, one or more of the following procedures
may be necessary:

A condenser can often be used to advantage on the electrically operated oil gauge or gas gauge.
Connect the condenser lead to the terminal of the gauge, and bolt the condenser case securely
to the frame or some other grounded part of the car.

Bonding the steering column to the fire Wall With a short braid may also be effective. Clean the
paint from the steering column at the fire Wall Where the Column enters the motor compartment,
and solder on a short piece of braid. Ground the end of the braid to the fire wall.

In some cases it may be necessary to ground the tubes and rods coming through` the fire wall in
order to reduce the interference, Clean them With ernery cloth and spot>solder the braid. fasten-
ing the end under a convenient screw.

In some cases it may be necessary to connect an additional condenser to the ammeter or to the
ignition switch.

lt may be necessary to use a condenser on the voltage regulator. The condenser case should be
mounted under one of the voltage-regulator mounting screws, or at some other convenient loca-
tion, and the lead connected to the battery terminal of the voltage regulator4

Interference from electric clocks can be eliminated by connecting a condenser to the ammeter
terminal4 The case of the condenser must be securely grounded.

If tirefstatic interference is noted in a particular installation, static collector springs should be obi
tained and installed in the front wheels of the car.
