MSD-5C

Can you ohm pins 5 and 3 for me for continuity to the ground wire and case? This one seems like maybe they're switched.....all my stock boxes pin 5 has continuity between 5 and the case of the module itself. This box pin three has continuity....makes me wonder if the polarity is different on/to the dizzy's side of the pickup or is there something a miss already with this one?
I'll get at it tomorrow
