Gran Fury V8-318 5.2L VIN K 2-bbl (1982)
Clock: Description and Operation
Regulation of electric clocks used on automobiles is accomplished automatically by merely resetting the time. If the clock is running fast, the action of
turning the hands back to correct the time will automatically cause the clock to run slightly slower. If the clock is running slow, the action of turning the
hands forward to correct the time will automatically cause the clock to run slightly faster (10 to 15 seconds day).
A lock-out feature prevents the clock regulator mechanism from being reset more than once per wind cycle, regardless of the number of times the time
is reset. After the clock rewinds, if the time is then reset, automatic regulation will take place. If a clock varies over 10 minutes per day, it will never
adjust sufficiently, and must be repaired or replaced.
WINDING CLOCK WHEN CONNECTING BATTERY OR CLOCK WIRING
The clock requires special attention when reconnecting a battery that has been disconnected for any reason, a clock that has been disconnected, or
when replacing a blown clock fuse. It is very important that the initial wind be fully made. The procedure is as follows:
1.
Make sure that all other instruments and lights are turned off.
2.
Connect positive cable to battery.
3.
Before connecting the negative cable, press the terminal to its post on the battery. Immediately afterward strike the terminal against the battery
post to see if there is a spark. If there is a spark, allow the clock to run down until it stops ticking, and repeat as above until there is no spark. Then
immediately make the permanent connection before the clock can again run down. The clock will run down in approximately two minutes.
4.
Reset clock after all connections have been made. The foregoing procedure should also be followed when reconnecting the clock after it has been
disconnected, or if it has stopped because of a blown fuse. Be sure to disconnect battery before installing a new fuse.
TROUBLESHOOTING
If clock does not run, check for blown clock fuse. If fuse is blown check for short in wiring. If fuse is not blown check for open circuit.
With an electric clock, the most frequent cause of clock fuse blowing is voltage at the clock which will prevent a complete wind and allow clock
contacts to remain closed. This may be caused by any of the following: discharged battery, corrosion on contact surface of battery terminals, loose
connections at battery terminals, at junction block, at fuse clips, or at terminal connection of clock. Therefore, if in reconnecting battery or clock it is
noted that the clock is not ticking, always check for blown fuse, or examine the circuits at the points indicated above to determine and correct the cause.
