48 Chevy truck ignition switch

Can anyone id the three terminals on a stock switch. Mine aren't marked and don't seem to have continuity between them

 

I Hope this helps.

 

Thank for the diagram. I've got that, but it doesn't I'd the terminals.

 

no continuity? it must be bad.

 

With the key in the "off" position there will be no continuity between any of the 3 terminals. If you look at the switch from behind the dash, the 3 terminals are kinda in a "Y" configuration. The bottom terminal is "Batt" or hot. The terminal to the left goes to the coil, the terminal to the right goes to accessories (if you have any)
