I'll take a shot at this..
The heavy Red is your wire going to the Fuse link on the main starter bolt on the solenoid..(about a 10 ga wire)...The Brown wire goes to the Alternator Charge lamp circuit...The Green wire that goes to the Ballast resistor is your "Run" position on the switch ......The Purple wire is the wire that goes to the "S" terminal on the starter solenoid...The other green wire may be for ACC...
One way to figure out how the switch is orientated is Ohm it out..With your DVOM set for Ohms, R X 1 Calibrated for 000, turn the switch to "Run" or on..probe two terminals at a time on the switch until you get a reading of 000, that will be your Main power and "Run" terminals..Make note of those two...
Pick one of the two you got a reading on and turn the key to the "Start" and hold it there (this will require the growth of a third hand and arm..
) and probe the switch..If you get no reading..go to the OTHER terminal you identified as "run" and probe again..
you should read 000..If so, relax the start function, the reading should go away..the terminal that you first Identified in the "run" Check is the MAIN power to the switch..you will take all your readings from this terminal to the other terminals..
with that, you will have main power, run and start..always use the main power terminal to ohm out the rest of the switch..to the other terminals and make a little drawing of it..hook your wires up accordingly..
If any of the functions don't give readings to the power terminal, you have a damaged switch..you'll need to replace it.
