Well, you certainly seem to know quite a bit about these switches. But what you don't know is that when holding the ign sw over to the start position while looking for a sweet spot on the NSS transfers all the current DRAW onto the NSS, where you don't want it. They want the NSS contact to be CLOSED and in full contact BEFORE the current draw of the starter circuit is initiaited. That way, it is the robost contactor bus bar of the ign switch that takes the spike and amp draw of the starter circuit.... not the contacts of the NSS...ever do any welding???? A good wat to kill a NSS. I leave you there . as there is an answer to justify everthing wrong. My preference is to do it corrctly from the get-go and to pass that info along in my diagnostic postings. To assume/state a mal-adjusted NSS, be it new or old, will not give you trouble is foolish info to be passing on.

Thanks everyone for your responses. I played with the shifter a bit, and the starter would turn for just a split second as I shifted from neutral into reverse before it cut out. I jacked up the car and messed with the alignment of the switch until I found the right spot... which doesn't have the alignment points precisely lining up anymore. I still feel like I should have gone with the OEM switch, it might have saved me a lot of time. Thanks again for all your help!

You may be slandering Febi here - which may actually be an OEM supplier, not sure. A 5/32 drill bit qualifies as a 4 mm rod. Needs to be short whatever it is.

For what it's worth, I have had three of these cheaper switches fail within a few thousand miles of installation. They were all installed correctly with an alignment pin as described in the MB service procedure. New shift bushings were installed in all three cases. Close examination of the third failed switch revealed that one of the 4 connection pins was loose in the plastic housing. I did not open up the switch, but my guess is that the internal contacts separated from the pin. I have not had any problems with the MB switch.

I'm afraid you are taking this too seriously.
While what you say about the current draw is true, if, however, the car requires only a fingertip movement of the shifter to engage the NSS, that is no big deal. A more serious issue should obviously be addressed, but in my case it is not a serious issue. (It's just a car, after all. ) [QUOTE=Arthur Dalton;1959336] I leave you there . as there is an answer to justify everthing wrong.

That's exactly what I used, to no avail. Perhaps the engineers should have incorporated a second alignment hole, to accurately position the body of the switch, so there would be no room for error.

Just a car, and it is your car....so......do as you wish.
The cars I fix do not leave without being correct. While you can justify an improperly operating NSS that YOU installed as being No Big Deal, my bet is if you had a TECH do the same job and the install of the switch had the same results , you would be jumping up and down to Beat the Band with complaints of the repair. Regardless, my point to the reader is to install the sw correctly from the start..that's all. I watched all your post back when when you made a project out of yours and was quite surprised to see you have such a problem with such a simple repair... But if you can live with your NSS Sweet Spot , go for it til that day comes... ...and it will come. My concern is not your car..... it is the people who care to know how/why of a proper install.

Quote:
It is obvious, and understood, what you were trying to communicate to DanielK and other readers about doing it right the first time. But since he was already past that point, and said "I have to move the shifter out of park and back into park for the car to start" I simply suggested he move it just to the bottom of park, and see what happens. My additional remark about having to find a new sweet spot is not standard procedure, but is precisely what a person would do in a jam -- especially if they remember posts like mine -- when installing it right the first time would not be an option, nor foremost on their minds. After that, they could go ahead and replace/realign the switch correctly. When mine fries, as you predict, I promise to post the news here so everyone can have a good, hearty laugh at my expense. Then I'll shell out another $25.00 for the part, and spend 30 minutes under the car, probably doing it wrong all over again.

Very Good...
I will close in this reminder to Members, and in particular to see that this important procedure Info gets into the Archieves..which is always my main concern. *FYI Note. NSS/Gear Shifter Alignment : "Be aware that after installation of this Electrical Switch, it is important to align the shift gate/shift rod/ and NSS in order to be assured of proper operation. Failure to do so can result in premature failure of the internal contacts of this Starting/Safety Interlock Switch . " A Dalton

And I will add for Members to pay close attention to your advice since it has been instrumental in many of my repairs.

Thank You..
My function here and on the other Forums I post on is simply to transfer what I have learned from others and past experiences in several different fields in my 50 plus years of playing around with many types of electro/mechanical devices..... Can't Dance , but do have some understandings of " dis kinda stuff .." "Experience keeps a Dear School that fools will learn in no other".. B.F. ..and we all know who B.F. was , don't we ????

True, but as the quote implies, and like most of my repairs, I had to look it up, and fortunately found the solution. You, on the other hand, did not need to do that, having learned the facts long ago. That's the difference between you Experts, and the rest of us...
Noneheless, we too come up with some good, uselful ideas every once in a while.

Absolutely.... Each and every person you have met, or will ever meet, can do something you can not or they know something you don't..........every single one of them..................... ..and you know you are finally getting smarter when you start to realize how much you don't know..
