I am trying to clean the terminals within the wiring harness connector that plugs into the ignition switch.   It seems like if you put the screwdriver in the right place they should be free.  Has anyone had any luck with how to do this, and have directions and tips for me? 

If I remember you did that to your JD that gave you a rough time starting.  I was awaiting your response on this thread eagerly.  I have the Black & Decker version of the rotatory tool.  Dremel has some nice cleaning attachments, I never knew existed.   What number do you use?  Did you cut any of the plastic on the connection doing this?   

AJ - I should have been more precise in my posting. I used a Dremel #403 on the ignition switch's male terminals that are actually ON the switch itself. For the connector's inside cleaning (female terminals), I use thin, modelling files (from my model building days) to get inside to polish them up.

Just trying to figure it out. 

My Sears YT16 was sold UNTIL it's starter wouldn't spin today. Guy came today to pick it up - figures. He wasn't happy, but I mentioned that this could have happened AFTER he brought it home! So after some quick diagnosis, I too, have a similar ignition switch contact problem. "Dremel'ed" the switch contacts, filed the connector contacts, but I get no voltage to the solenoid. Worked on it in the rain, so I wasn't 100% thourough. Wire to solenoid from ign switch has good continuity. Have 12v at the "B" terminal. I jumped "B" to "S" (solenoid) at the connector & it still doesn't spin over. I either have a broken wire or completely corroded terminal INSIDE the plastic connector. Guess I'll have to use crimp, spade type lugs to repair this...

I guess you don't have 12v coming to the starter wire (where is connects to the starter terminal).   If not it's electrical, if so then the start is either faulty or it needs better ground. 

I found out how these terminals come out of the connector.  Just simply insert a precision screwdriver into the proper connector where the clip is and bend it back.  I took a pic. 

That clip needs bent back and the whole butt connector just pulls out.   You have to bend it back into place when you install it again. 

AJ - GREAT post & pics!!

I found my problem. After cleaning the ALL ignition switch terminals, I still had the problem. Back to square one. For some reason I would lose my 12 volts at the switch when I engaged the starter. The culprit ended up being a corroded, melted fuse holder with only 22 gauge wires feeding it ....  Replaced it with a quality, automotive type & we're good to go.
