hey guys,

the setup i'm thinking of cosists of two standard horn style relays (as in pins 85 & 86 on coil side, pins 87a 87 and 30 on the high current side), wired together to operate a door solinoid both ways.. tired and just for the life of me cannot remember how to do it, any help appreciated :rolleyes:

cheers,

marcus

Soo... 87a is the circuit for naturally closed, and 87 is naturally open.

You've got a single pole, double throw relay right? SPDT

So when the coil is activated, 87 will join the circuit. When the coil is off, 87a will join a different circuit. I'm not sure what exactly you're doing, or how you can join two of them together though...

A double pole, double throw will let you join one circuit while turning another one off, and then vice-versa.

As far as how to "do it", i'm not sure what you're exactly doing. =-[

hey,

yeah that's it, voltage over 85 & 86 joins 30 & 87, if there is no voltage over 85 & 86 then 30 & 87 are always connected..

basically the 200ma that my alarm supplies to work the door solinoid forward and backwards is not enough current to work it. there are only two wires coming out of the alarm to connect to the solinoid which i think is a pretty standard setup, to work the solinoid one way it suplies a current over these wires, and to work it the other way it inverts that current..

what i'm trying to do is wire in a relay so the solinoids have enough power open and close the door lock.. my problem is that by using a relay the solinoid will only work in one direction, as the relay kills the alarms ability to operate it in the other direction as the change in polarity won't go through the relay.. i think..

i remember seeing a way in a previouse alarm install done by somebody else where they had two relay's wired together to perform this task.. this is what i'm after :( any help would be great :)

cheers

do this:

87 -+12v

87a - GND

30 - motor

85 -+12

86 - alarm

do both relays the same way and stick a 20A fuse on the supply.

what car btw. there may be a MUCH easier way of doing it :(

    • Kinda glad I never got to this ..    https://www.facebook.com/groups/1483859159195077
    • @GTSBoy This method was able to get readings of -10 to -2, so it looks like its monitoring.  Now I need to figure out why the vacuum on the line provided isn't alternating with manifold pressure.  I went with 2 lines that an RB25 tuner recommended but I'll get a longer hose and try directly off the back of the manifold.  He may have been used to OEM intake setups while I have a DBW setup that removed the MAF and IACV.  
    • I work at a car detailing and tinting shop called Quark which gets all manner of German cars in usually (mainly due to a contract with Mercedes Benz Kita Osaka, BMW Nishinomiya and others) but every once in a while something special comes in, like a fully restored 1972 HS30 Nissan Fairlady 240ZG... The shop owner had immediately started applying film to the windows as soon as it was in the shop so the interior was completely covered in towels and plastic sheets. But I could get a few photos of the engine bay which was restored like new. Such an amazing car to see in pristine condition in Japan these days.  
    • Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.
    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
