HELP!

Got the whell/dash apart and noticed that my 'late' (75) tumbler etc is different from those pictured in the Pelican how to article..

Anyways, the old white plastic part came out when I pulled on the plug from the back. The part looked good, no cracks. But since I have a new one, I plugged in the the new white plastic switch, inserted it from the rear until it seated in, tried to start... and had the same problem, no starty.

So I tried the screwdriver test on the old and new switches, both will start the car. So it seems that my tumbler piece is not turning far enough to engage the starter. BUT, I cannot get the tumbler portion out of my dash. The 75 piece is different from the early pieces and I can't seem to just turn the key and pull. Something is holding it in but I see no set screw or anything. Any ideas how I can get that thing out?

Thanks!

There is a spring clip holding the key tumbler in th housing. and a paper clip is enough to depress it. and a itty bitty set dcrew holding the plastic contact part in the housing.

giving up slowly...

I see the spring clip in the little slot. I've deressed it and I'm able to pull the tumbler out about 2 millimeters.. thats it. I don't see a set screw anywhere.. do you mean on the white electrical part or somwhere else?

Attached ImageAttached ImageHere are a couple of pics of my ignition. I can stick a small screwdriver in the slot (marked with the arrow) to depress the spring clip.. I can pull it out a smidge but thats it. I can see that the clip is depressed when I do this.

What gives?

Ok, I found an earlier post with info on my 75 ignition column assembly. Seems that I have to pull the whole thing off.

This was a pic from that post:

I've pulled mine off. There is talk of a set screw. I'm not sure if this is to hold the white plastic part or the tumbler part itself. The white plastic part just unplugged. Here is a pic of the back of my assembly. Any tricks to this besides the spring clip I mentioned earlier?

Ok, so get this..

I appear to have a bit of the 'twist' in the mechanism that turns the switch. So I did like Moggy etc and ground down one of the tangs so I'd get more rotation.. maybe only a few hundreths.

Now.. if I take the tumber and stick it in the switch (outside of the entire column housing), I can turn and start the car. However, if I plug the tumbler in the housing and the connect the white switch in the back, I can't get the starter to engage.

Do I need to ground more off or is there something else I'm overlooking in regards to the housing??

Thanks for any help!

Regarding the tangs.. when you turn the key, part of the tumbler rotates and hits a 'tang' I guess you call it. There is one to keep the key from being turned backwards as well. Anyways, I took a little off of the one that stops the rotation during 'start'.

Strange that if I just plug the tumbler into the white plastic switch while holding both in my hand, I can start the car.. put it back in the housing and no go.. trying to figure out why.

How did you wire your push button?

I suspect you need to grind off more. or the set screw that holds the white plastic part in is not doing it's job very well.
Keep at it. your close. I thought the push button was a PITA when a DAPO put one in an old bug of mine.

Thanks guys.. I'll keep grinding. Actually, I don't have a grinder, I've been filing.. ugh. Maybe a trip to the hardware store for a dremel is in order.

Regarding the set screw.. there wasn't one. It seems that the switch fits in tight but I should probably find something to stick in there anyways.

Yup, I don't like the push button either, but I do like my car starting. I spliced the switch between the black wire leaving the switch and the yellow wire. This way the button only works when it's switched on. I mounted the switch under the dash so I didn't have to drill a hole in the dash. To remove it I just have to pull two splices and the button and you'll never know it was there.

Now I have to tear into this again to see these tangs. I'd love to remove the button.

I'd love to see a pic of the tangs. I am not sure what you are grinding off to get more rotation.

Strange that if I just plug the tumbler into the white plastic switch while holding both in my hand, I can start the car.. put it back in the housing and no go.. trying to figure out why. ---When the tumbler and switch are out of the housing you are able to insert the tumbler further into the switch. THe hosing will only allow for a given amount of insertion of the tumbler into the switch receptacle. The additional insertion causes more pressure to be applied to the internal parts of the switch which results in earlier contact.

Doug.. thanks for the explanation.. I thought I was going nuts. (IMG:style_emoticons/default/blink.gif)
I didn't get the picture last night, too busy running around town and didn't get to work on the car. I'll do my best to get it tonight.

Here is a pic of my tumber.


The RED arrow points to one of the TANGs.. not the one I'm grinding but the stop position tang.

The BLUE arrow points to my TWISTED end that fits into the white plug.
