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.

Do you have a continuity tester or a multimeter?

Ask Your Own Small Engine Question
Customer reply replied 10 months ago
I have both

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

Ask Your Own Small Engine Question

Let's use your continuity tester.

Ask Your Own Small Engine Question
Customer reply replied 10 months 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).

Ask Your Own Small Engine Question
Customer reply replied 10 months ago
ok

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

Ask Your Own Small Engine Question

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

Ask Your Own Small Engine Question
Customer reply replied 10 months 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 reply replied 10 months 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.

Ask Your Own Small Engine Question
Customer reply replied 10 months 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.

Ask Your Own Small Engine Question
Customer reply replied 10 months ago
A2

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