Hey, guys:

I've 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.are these clocks the old
"repel and tick down" 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'm trying to determine if the 12V draw I
have from the clock is what is supposed to happen.

Thanks,

Andy Walker

Edmond, OK

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.
