I tested the key switch as per your instructions and the test was NO GOOD. The switch I used to replace the 5 pole switch was a #327355MA. The test for continuity is as follows. CIRCUIT M+G is off, B+L is ON, and B+S is start.
The back of the switch is clearly marked. The only problem I encountered is that the key falls out of the switch. The test in the video shows that the switch is bad and it cost me 25.00 to find out. -
Wow this is very informative and I was able to test my key switch to find it aint working. problem is i do not know the part number. i have a model number for tractor noma D4314-100 (old!) The switch has zero terminal markings. 5 pole three position. If I trace the the wire harness wires back and find out which ones of (LBMGS) go to, can i just buy any switch that has 5 poles (example oregon 33-397) and simply switch the wires to fit the harness in the right position to correspond with the new switch? I actually tried it but the first position simply pops the 25 amp fuse at the battery. Any ideas?

How do you remove the switch? I can't get mine off.

Could a faulty switch cause your mower to turn off while it is running?

Josh , boy do I owe you . This video saved me about $ 200.00 . I followed your instructions ; removed the ignition switch from position , tested the ignition switch and started the unit .... but it wouldn't go "off " ! As a last resort I put the ignition switch back in it's position and secured it with it's nut . Turned it on = ok ; turned it "off" & it went off. I never thought about the ignition switch NEEDING TO BE GROUNDED ! !
Hope this small move helps someone else .

very nice tutorial, was looking at trouble shooting the mower was not starting (not even clicking) seen this and quickly take off the switch to test and found it really was faulty switch and then try clean with wd40 and the switch start working again. good job on the tutorial.
