I have a 3 pole ignition switch w/mounting ears on body that match-up w/bracket and allow for flush mounting in dash. I have one key that allows a short throw from the 12 to 2 o'clock position.It checks out ok electrically. I can also function the switch w/out the key. This tells me the little guys inside are frozen or non-existant. I want to remove the tumbler, so I turn the key and insert the pin into small hole in face, feel the pin depress and thats it. NADA, one hour of NADA What am I doing wrong??
