Winter season will soon be upon us, and my '73 850 is my first bike with a positive ground. I use a CTEK 800 battery tender for the 12V battery on my negative ground Hinkley Triumph. The CTEK leads are hard wired to the bike, CTEK +ve goes to the positive battery terminal, and -ve goes to a ground on the bike's frame. Now, on a positive ground bike, would the CTEK -ve go to the battery's negative terminal, and the +ve to the bike's ground? Both bikes will be in an insulated garage, with occasional heat from a gas furnace. Should the battery be removed from the bike for winter, and maintained with the CTEK, while on the workbench? By the way, can someone confirm for me that the electrical system on the Commandos are 12 volts? I know that the coils are 6 volts.
thanks
