Hello, my name is***** and i will do my best to assist you.I am going over your story now and will reply back soon with some info,thanks!

Bob testing an ignition switch is pretty simple, there will be one power input and the other terminals will all get power at different points of the ignition being turned.

if you can send a picture of the bottom of the switch there are numbers near each terminal that tell you a circuit.

I can use those numbers and tell you at what position they should have power.

Is your mower a Columbia or a John Deere?

Customer: replied 29 days ago.
john deere

Thank you for confirming. I read your earlier post and you posted Columbia Lawn Tractor.

Do you have a continuity tester or a multimeter?

Customer: replied 29 days ago.
I have both

Very good! Have you removed your switch from your mower?

Customer: replied 29 days ago.

Let's use your continuity tester.

Customer: replied 29 days ago.
ok

Look at the bottom of your ignition switch. Each one of your seven prongs will have an identifying letter either stamped into it, or stamped next to it. Look for a (B) and a (S).

Customer: replied 29 days ago.
ok

Check for continuity between (B) and (S) when your key is in start position.

There should be continuity between these two terminals only when your switch is in start position.

Customer: replied 29 days ago.
all terminals B,G,S,M,L,R1 & R2
yes continuity on B and S in start position
yes continuity on B and L in run position
yes continuity on G and M in stop position
Customer: replied 29 days ago.
sorry
all terminals B,G,S,M,L,A1 & A2
yes continuity on B and S in start position
yes continuity on B and L in run position
yes continuity on G and M in stop position

Thank you for checking. Your results indicates that your switch is ok.

Customer: replied 29 days ago.
what is A1 and A2

A1 powers your fuel shut off solenoid, etc. In on position, there should be continuity between B and A1.

Customer: replied 29 days ago.
A2

In run position there should continuity between (L) and (A2).
