hey guys, I've been trying to hook up my train horns to the aux output on my alarm. I got a relay a couple days ago (30 amp auto relay, 30, 85, 86, 87)

According to my alarm manual, the relay should be hooked up as follows.

30- Trunk Solenoid, Dome light, or Aux Function
85- Green/Red or (-) Aux Output
86- +12V Constant
87- +12V Constant OR Ground (test activation circuit in vehicle. Connect +12V for Positive circuits or Ground for negative circuits)

I'm so confused. I hooked up the 30 to the positive wire of the horn switch ( I tapped into it). I hooked up 85 to the alarm's green/red wire. I hooked up 86 straight to the battery's positive. And I hooked up 87 to Ground.

What am I doing wrong? When I press the aux function on my remote, i can hear the relay switching, but nothing happens. Please helpppp!

 

i think you are going to have to run another wire to te horn because if the switch isnint on then it doesnt get an power because the switch is blockin it

 

to what side of the horn? the ground? and from where?

 

another positive because your switch is of there for blocking the electric flow

 

right, but i already have a positive running to the relay

 

I would almost bet it is giving you a negative output. Do you have a test light?

Also, did you tap into the wire that goes to the horn? Or the wire that gives you horn switch power?

Another if may be that it is not a long enough signal output to open the valve to blow the horn, it needs to be open for about 5 secs.

Which alarm are you using also.

 

i have a volt meter, no test light.

and yes, it is a negative output, but I have no clue what this means

 

Ok, thats the problem, you need to send a + signal to the horn.

Do this



You will need another relay. Hook the wire coming off of 30 from your first relay to the 85 of the new relay, and follow the rest of the instructions.

 

Screw all that, run a + to the 87 of your first relay, then report back.

 

I tapped into the wire that goes to the switch to the horn (it's my factory horn switch wire, that i extended to go to my horn's solenoid)

I'm going to switch the aux output to #3 (which gives you the option to program it to however long you want it to be open for). The current signal output is only 0.5 seconds.

I'm using a Crimestopper CS-2900 DPIIFM. It's remote start/alarm.

 

hahahahah lemme go check!

 

Yeah, use the aux output.

 

It works!!!!!!


Thank you soo much

 

No problem, did you get the problem with the alarm going off fixed?

 

sure did!

they had to wire up 2 more diodes, like it was shown in the diagram in my thread. everything works flawlessly now.


thanks so much for all your help!

 

No problem man, glad I could help.
