Andy,
The answer is that your clock is none of the above. It neither winds =
and then ticks down, nor does it have a motor. The movement in the =
Tiger is basically an escapement with an electromagnet that attracts the =
escapement causing it to rotate. A pair of contacts is arranged so that =
a pulse of current goes into the electromagnet for each half of =
it=E2=80=99s rotation causing it to oscillate back and forth. The =
oscillation is at several Hz so even though the drain from the battery =
is in pulses it will seem like a continuous drain.

Subject: [Tigers] Tiger clocks
Hey, guys:
=20
I=E2=80=99ve got a 12V draw on my battery at all times that I have =
determined is coming from my original-style clock in the dash of my =
Tiger. When I unplug the clock, the draw goes away. My question is =
this=E2=80=A6are these clocks the old =E2=80=9Crepel and tick =
down=E2=80=9D style (where the points repel each other and swing away, =
thus winding the clock and letting it keep time on the spring, until the =
process happens all over again), or do they need 12 volts to the motor =
all the time to keep running? I=E2=80=99m trying to determine if the =
12V draw I have from the clock is what is supposed to happen.
=20
Thanks,
Andy Walker
