shutting down sensors for rs

trying to shut down a sensor for when rs.

86= fused 12v constant

85= ground while on rs from rs unit

87= not used

87a= to one side of the power wire to the sensor,brain side

30= to the other side of the power wire of the sensor,sensor side

checked the output of 30 and i dont have 12v, reversed the wires and still no 12v output. the ground output from the rs works fine. any ideas? in other words theres no current flowing through 87a to 30 when the rs is off.

what do you think?

85= ground at all times

86= 12v in the run position only, from rs or car.

30= one side of power wire to the sensor, brain side.

87a=other side of power wire to the sensor, sensor side.

still cant figure out why the above diagram wont work. ideas anyone?

you wont have anything on 30 when triggered.....cause theres nothing on 87......you are just "opening" the wire with your relay set up as you have it listed.     

87= not used

If you want 12v at 30 when triggered...you need 12 v at 87

right, it will open the passage between 30 and 87a when  86 receives 12volts, causing the sensor to shut off because there wont be any current(12v) getting to it, right? in other words im interrupting current to the sensor, at rs. or if using the acc. wire from the car, i would shut it down every time the car is running. right?

i had a problem like urs....the relay wasnt trigger fast enough to bypass sensor quick enough i never figured out how to fix it.....try droping ground...that might work

Where theres is a wire there's a way.

The diagram that you have it right if you are trying to interupt the power wire when the remote start GROUND WHEN RUNNING wire is activated. If you place 12 volts on the 87 pin, your essentially doing nothing. Is this a dual or single trigger sensor ?

dual stage, microwave and shock sensors. thats why i want to shut down power on rs. tried working on it today after work with both diagrams but no luck. if i use the second diagram i mentioned i pop the rs fuse. getting frustraded but still hanging in there. any more ideas?

can i be getting feed back through the coil causing the fuse to pop? should i use a diode like on the starter kill?

Are you using one relay per sensor or just one for all three ? Also what do you mean by shutting down power on the RS ? Or did you mean shutting down power DURING remote start ? I've done this before on a system and I wired each sensor separately while breaking the wire like a starter disable relay configuration.

im using one relay to interupt power to both sensors. using the ground when on rs from the rs unit doesnt shut them down. thats why im trying to use th acc. wire from the car to trigger the relay open when it receives 12v. that way when the rs starts the relay will be open and the sensors wont trigger. would i need to use a diode like on the staret kill diagram?

85=ground at all times

86=12volts on run only from acc wire

30=one side from power wire to the sensors

87a=other side of the power wire to the sensors

That should work to do what you are doing.  You shouldn't need a diode.  Is there one on there now?  If there is a diode on the relay harness and its facing the wrong way it will pop fuses.  I would stick with the (-) while running signal, too, as it will cut down on how often that relay engergizes.  As you have it above every time they start the car with the key they'll hear the relay click (which may or may not drive them crazy).  Good luck!

no diode yet, but fuse on rs pops, thats why i thought i would need a diode just like on the starter kill. its on my own truck, so i wouldnt mind the clicking as much as the sensors tripping.

You might have already fixed this, but are you sure you have it wired exactly as you listed? Can't see why your fuse would pop, since all the relay is doing is connecting two ends of a wire that you've split in the middle.
If you leave the coil connections unconnected (85 and 86), does the RS fuse still blow?
If it does, that would imply your fuse would have blown even before you tried inserting the relay inline.
