I am going to fabricate one of these and install it in my car and I was wondering if anyone wanted me to make them one while I was at it. PM me if interested. https://www.carsound.com/cgi-bin/UBB_CGI/ultimatebb.cgi?ubb=get_topic;f=3;t=002286;p=0

Are all shifters ungrounded? If your shifter is grounded then you can not use this set-up right. You have to put a switch before the positive lead reaches the springs so that incase a spring breaks you can shut off the whole circuit right. The springs have to be big enough to carry the small amount of current from the circuit and also sturty enough to withstand the constant friction encountered with the shifter. The shifter is going to get really scratched up and eventually the springs will need to be replaced. It does seem like a good idea but it needs some perfection. I'm a real d*** huh. ------------- Poly Dollies

This does sound good but you really have to check and see if shifter is not grounded. I'll check mine right now. ------------- Poly Dollies

My shifter is not grounded. Don't you think there's a reason why they're not grounded. The manufacturers must have purposly isolated the shifter for some reason. Maybe it was just to prevent a shock hazard. I wonder if the shifter is always grounded. Has anyone tried using that spring set-up succesfully? I didn't read any results in his post of people actually trying it.

If you wanted the shifter to remain ungrounded you could put some sort of rubber insulator around the shifter and a conductor around the shifter at the point where the springs will be contacting it. I guess this would be another part that could fail if not designed properly.

Well, I was talking to my dad and he said something and it made me think of putting something around the shifter. So yes, I believe that if we put a kill switch somewhere in the center console or something, on the shifter, under the boot, under the dash, just in case, we could shut the thing off until fixed. I think a rubber insulator would be a great idea and putting a conductor around that. That way, the shifter doesn't get rubbed up. I am thinking maybe a thick metal sheath clamp. Any ideas?

A sheath clamp is like a big round clamp for large wire right. I guess it will be alright if it's an insulator that will stay in place. There should be a reason why the shifter is not grounded. Does anyone know or is this a question better suited for a mechanic.

I was just making up some word combo's. You know those clamps that go on hoses under your hood? I was thinking something like that so it can be adjusted depending on your shifter diameter. and the clamp will be also to keep the insulator in place. If it moves, the remote start won't work. Just keep that in mind. Another great safety feature :)

Ohh, those clamps. Hopefully they will not slip afer time. If it does slip off the springs will contact the shifter right. (they will contact when you shift. Would it be a good idea to put a small in-line fuse? ------------- Poly Dollies

Remember..the shifter is ungrounded, and most do not have bare metal. So this should not be a problem. And if they do slip, the remote start will start engage. Just another safety feature ;) If the through the shifter is loaded, then yes, it would be a good idea to put small in-line fuse in there before and/or after the shifter. I'm guessing you're interested in one of these units? I am going to try to fabricate one today. Not going to use the same brackets as he did, just fab my own.

This is a great idea there man,But remember this setup wont last long,due to the fact the friction overcome everything.Endless spring breaks.Did you know that shifting gears from 1 to 5 Is a lot of strain on the setup you have.My uncle said to me use a 12v lazer set up across the gearstick.When the lazer light brakes,power will be restored to the relay to work the remote start.

If you do use a lazer you would actually need to put two sets so that the signal will break if it's in gear right. If you only have one to detect if there's an obstruction by the shifter in neutral it could be a problem if something else got in the way like trash or a bad lazer right. Have you looked into this? I wonder how reliable and expencive they can be.

We'll just have to find out, won't we?!

The gear shift lever isn't grounded because the factory isolates it from the surrounding metal (transmission, floor pan, etc.) with rubber or teflon insulators so vibration and road noise isn't transmitted up the shifter and into the car. Another reason they do this is to minumize wear on the hard parts (the ball on the end of the shifter lever and the receiving "cup" in transmission). If you've ever driven an old Toyota pickup truck you probably have noticed the shifter has a LOT of play. This is mostly due to the teflon insulator being worn out, replacement will almost perfectly restore shifter feel. Theres no special voodoo reason the shifter isn't grounded, its just not grounded as a by-product of design.

I talked to my electronics professor today and he was thinking that maybe a limit switch or a magnetic reed switch would work. Then I realized that the best way would probably be to imitate the mechanism of a car that has a neutral position wire. Does anyone know how a neutral position switch/wire works on a car that comes with it? I think I remeber driving my friends ford focus and it displayed the gear the car was in. ------------- Poly Dollies

small lazer under the gearstick boot will do the trick but you are right,it is expensive.I know of spy shops selling those in my country
