I've got a 41 av that im trying to rewire the lights. I pulled the switch and i'm not sure how to tell which terminal is to the battery. i figure if i find that one i can use a meter to test the continuity and figure out the rest. Thanks
 
Many pictures of light switch wiring both here and google. type in Farmall A 4 position light switch Jim
 
Sometimes switches are marked bat,but not always.I doubt you could find a diagram of the switch.But with a meter,only 1 terminal should show continuity to all of the others in various positions.Mark
 
Presuming your AV has the original switch, generator and cutout, here are the switch connections.

It was not the origanal switch at some point
someone replaced it. I did the continuity
test and determined the switch is bad.
Thanks everyone for your help!
