12V conversion discharging battery

I have a 12V conversion discharging battery over night. per Smiths old ford web page
"Get a universal ignition switch at the auto parts store that has an ACC (accessory) position as well as an ON position. Hook the exciter wire to the ACC terminal instead of the ON terminal and you're in business. No diodes or lights are necessary." This is how my tractor is wired but when I checked today the ACC terminal is hot all the time not just in the ACC and ON. Its hot in the off position. Do I just had a bad switch? Tractor turns on and off fine, battery is taking a charge, amp meter works but leave the battery hooked up over night and the start won't even click. tried several batteries.
 
rlp.......there are several auto parts store replacement ignition switches sold. Smith's general instructions are well advised. You just have a BAD switch. Unfortunately, most electrical stuff is sold, non-returnable. And yes, yer BAD ignition switch AUX terminal is discharging yer 12V battery. ........Dell, a 12V advocate for the right reasons. I know 8-ways to convert to 12V and they all work. The AUX ignition switch trick is one of my 8-ways that work.
 
well now I know whats broke and can fix it. switches are cheaper than batteries. NO MORE PARTS FROM TSC! Thanks for the help.
 
rlp,good advice but i would check the switch before taking it back. get a voltmeter, remove all wires and check between accy terminal and bat terminal with no key in the switch..continuity means a bad one. napaguy
