this positive power source MUST
BE UNSWITCHED, but should
be protected with a fuse);
b) the light switch (also after the
fuse in the fuse box); and
c) a good ground location (i.e.,
anywhere you can conveniently
bolt the wire to the chassis of the
vehicle).
2. Connect the appropriate positive (+)
and ground (negative [–]) wires to the
clock and clock lamp socket as shown in
Diagram D.
Wiring the Engine Hour Meter
1. Run wires from the Engine Hour Meter
location through the firewall to:
a) the positive (+) terminal on
the ignition switch (after the fuse
box);
b) the light switch (also after the
fuse in the fuse box); and
c) a good ground location (i.e.,
anywhere you can conveniently
bolt the wire to the chassis of the
vehicle).
2. Connect the appropriate positive (+)
and ground (negative [–]) wires to the
Engine Hourmeter and Hourmeter lamp
socket as shown in Diagram C.
At this point, the installation and wiring
of your new VDO Quartz Clock/Engine
Hour Meter is complete. Turn on the ignition
and the lights in the car and check to
see that the clock/hourmeter and light are
working properly. If they are not, recheck
your wiring.

c) the positive (+) terminal on
the ignition switch.
2. Connect the wires from the alternator,
starter and ignition to the terminals on the
back of the ammeter as shown in Diagram
C.
3. Connect the wire from the light switch
(after the fuse box) and from a ground location
to the ammeter light switch terminals,
also as shown in Diagram C.
At this point, the installation and wiring
of your ammeter is complete. Turn on the
ignition and start the engine to be sure the
ammeter is working properly. If it isn’t, recheck
your wiring.

é
Instrument Mounting Diagram A:
1. Prior to any work on vehicle's wiring
system, removing the (-) negative battery
cable from the battery to disable battery
power.
2. Find a suitable location to mount the
instrument where there is ample depth to
secure and wire instrument.
3. Cut a 2 1/16" (52 mm) diameter hole
in the location selected. Instrument should
fit into hole easily without forcing. Forcing
it may cause damage to housing of
instrument.
4. Secure 'Spin Lok' clamp (Diagram A)
on to instrument. (Note) the 'Spin Lok'
clamp is designed to work in thin panels
as well as panels up to .8" (20 mm)
in thickness. Consequently, if 'Spin Lok'
clamp is installed and will not securely
fasten instrument, remove, reverse and
re-install.
5. If you are using optional metal mounting
bracket, install with mounting nuts,
For thicker panels it may be necessary to
trim legs accordingly.
Clock Wiring Digram C:
1. Wire + terminal to a fused 12 v battery
source that is not switched off when
vehicle ignition is off.
2. Wire - terminal to a good ground
location.
3. If the instrument you have purcased
has an illumination terminal K, wire to
the light switch of the vehicle so that the
instrument light turns off and on when the
switch is operated.
4. Reconnect battery ground cable and
test for operation.
CAUTION!!!
Secured with Spin- Lok or metal
braket tight enough to prevent rotation
of instrument.
DO NOT OVER TIGHTEN
INSTRUMENT OR DAMAGE
WILL OCCURE TO HOUSING
AND BEZEL.
Hour Meter Wiring
Option 1- Digram C:
1. Wire + terminal to a fused 12/24v
battery source that is switched off when
vehicle is not in operation.
2. Wire - terminal to a good ground
location.
3. If the instrument you have purcased
has an illumination terminal K, wire to
the light switch of the vehicle so that the
instrument light turns off and on when the
switch is operated.
4. Reconnect battery ground cable and
test for operation.
(Note) Since the hourmeter registers
in 10 th of hours, it will take 6 minutes
before hourmeter will show movement.
Hour Meter Wiring
Option 2 - Digram C:
1. Wire + terminal to a fused 12/24v
battery source that remains on even
vehicle igniton is off.
2. Wire - terminal directly to a normally
open engine oil pressure switch.
When engine is started and oil pressure
CAUTIO
rises the pressue switch will close and CAUTION
the hour meter will begin to operate.
3. If the instrument you have purchased
has an illumination terminal K, wire to
the light switch of the vehicle so that the
instrument light turns off and on when the
switch is operated.
4. Reconnect battery ground cable and
start vehicle. When oil pressure present
observe operation of instrument.
(Note) Since the hourmeter registers
in 10 th of hours, it will take 6 minutes
before hourmeter will show movement.
Clock Setting
1. Button on bottom left of clock face
will set counter clock wise
2. Button on bottom right of clock face
will set clock wise
3. By hold left or right button down
will make the clock set faster
