6V neg or 12V

[416Ford]

Rebuilding an old clock to put in my street rod and I was wondering if I will have any issues with the points set up on the clock?
I can manually get the clock to work. I hooked up a 7 volt tool battery in reverse polarity and got sparks but that was prior to freeing everything up.
Will I be able to use the clock with 12 volts and if so will I need to hook it up in reverse? My brain tells me that the points don't care as long as it has pos and neg.

    Why are you trying to make time fly   :?:  :?:  :?:  :?:  :?:

For some of us it goes plenty fast as it is ......    :oops:

Most automotive clocks it doesn't matter what the polarity is, or what the voltage is. The current just winds the clock spring until the points lose contact, then shuts off until it needs winding again. 6 volt clocks generay work fine with 12 volts. https://www.oldcarsweekly.com/restoration/putting_the_ticktock_back_in_your_old_car_clock

Hoping to hook it up to 12v neg ground and go back in time.  


Thanks for the link and info Frank.
