Hey guys, I'm using a Crimestopper 2012TW1 in my 2004 Grand Am GT. I'm having a problem hooking up both my Domelight Supervision, and Horn Honk Features. The Output from the Unit is 200 Mila Amps Negitive for both. How do I wire a Relay to convert the 200ma Ground signal to a 12volt Ground Signal? Also, my 12+ Alarm Siren Output wire is constantly showing full voltage, even when the alarm isn't triggered. This unit was in a different vehicle of mine a few years ago, and when I sold it, I took the unit out. When I went to hook it up, I heard something ratling around inside the brain box. I opened the box and there was a 3 prong transistor, or voltage regulator loose. I found the place on the board that it goes to, and re-soldered a 12 volt voltage regulator I got from Radio Shack. Still getting the same problem. I'm pretty much over trying to get it to work. However, I'd still like to find a way to energize the Siren even if by pulse, when the alarm is triggered. Any Ideas? ------------- The Only Stupid Question, is the one Un-asked

Constant power to terminal 86
200 mil out of alarm to 85
Ground to terminal 30
Your new high current output 87

Is that a Negitive, High Current Output? Because, I'm wiring from a Negitive 200ma to a Negitive wire at the BCM

Correction...... It's a 500ma wire comming from the Brain, NOT 200ma.. Sorry Guys ------------- The Only Stupid Question, is the one Un-asked

200 milliamps, 500 milliamps, it doesn't really matter. The relay wiring I provided will take this trigger from the alarm and give you basically a 30 amp capable ground. You did say you needed a 12volt ground output. If you needed a 12volt positive output, let me know.
As far as the 7812 you got from radio shack, Did the component that fell out of the alarm have any readable numbers on it? Why did you choose a 7812 to put in the unit? Pull the 7812 back out of the unit and see if the siren is still going off all of the time. My guess is that the device was actually a transistor and not a regulator. Don't just go running back to Radio Shack and buy any transistor. They all look alike but believe me they are not the same. We can figure out what kind of transistor you need.

Ok, the numbers are very hard to read, but here's my best shot 1st Line wod8 2nd Line Moroco or Horoco 3rd Tip 32c or 320 The first letter in line 2 and last number in line 3 are realy hard to read I hope this helps Idiot, I highly respect your opion, I've read TONS of your posts so far. Thanks for your help ------------- The Only Stupid Question, is the one Un-asked

Thanks for the thoroughness in your answers. That would be morocco and TIP 32C. And Lucky for you Radio Shack sells a suitable replacement for your application. A TIP42G will cost you a $1.59 RadShack
Remember when trying to remove the regulator it will be easier on the circuit board if you add extra solder to the joints, then heat up all 3 legs and gently pull the regulator out. Use pliers not for extra force, but so you do not leave fingertips on the tab of the regulator. You may want to check the old tranny and see if it is OK. It may have just fallen out of the board.

Thanks, I'll pick one up today, and give it a shot. Now from a pro active standpoint. If this doesn't work, is there any way to use another trigger wire from the brain to trigger my alarm Siren? Here is the online manual.... https://crimestopper.com/techweb/InstructionBooks/ComboSystem/cs2011_2016dp_30option_ins.pdf I realy like this unit, it has a lot of good features, and everything else works great, but without a siren, all I have are a bunch of flashing lights. Here's the other thing I haven't added yet. The car is actually my Brother in law's. He is on his 3rd tour in Iraq for the Marine Corps, and his other car was stolen right off of base! Which is why I'm doing this for him. He doesn't even know that I have his car yet. It's a supprise for him when he gets home, so I'd like to have this done right for him. It's the least I can do, for him, for fighting for my right to be a jack ass lol. ------------- The Only Stupid Question, is the one Un-asked

Why would we not be able to fix the alarm? We can rebuild it, we can make it stronger than it was before.

Any Ideas youu have on making it stronger, I'm all for! What Ideas do you have?

The make it stronger thing I said was a quote from the TV Series, The Six Million Dollar Man.
You sounded like you were doubting that we would be able to get it fixed. You were the soldier in a situation that you KNEW could have no good outcome, I was being the Drill Sargent that was talking you into believing that we were going to be able to pull it off.

Picked up a relay today, hooked it up as per your instructions. Didn't work.... I think it's my fault, the relay I got ended up being a 60amp... I'm sure that's the problem, what do you think? Also, they didn't have that transistor in stock today, they promised to have one by noon tomorrow... I'll keep you posted

As long as the relay has a 12 volt coil, it should work. Did you check the old transistor? Or did you just put it back in the board to try it?

I got the transistor you recomended, installed it (properly) and it's still showing 12v + constant. Without the transistor, the wire is dead. I'm pretty much tired of screwing with it, so I'm going to go another route. Here's my idea.... I'm going to wire the negitive 500ma horn honk wire to the siren. Once I get that damn relay working... I'm on my way out to the car now, so I'll post again, with an update ------------- The Only Stupid Question, is the one Un-asked

If you do use the horn honk wire, the following diagram should give you a constant output to power a siren. 
It was designed to give you a constant out for sidemarker lights using a pulsed out from blinkers. You can substitute blinker wires for horn output wire and the output to turning lamps will now go to your siren.

Might need to rearrange it if he's going to use a (-) output for the relay. If it's coming from a (+) turn signal as shown, don't forget to diode isolate the output from the alarm or the siren will go off when you signal a turn- 
The 10K resistor could be also be omitted for simplicity, since it won't really have much effect compared to the relay coil.

Sorry guys I never got to work on the car today, one of my friends was hit by a loving drunk driver! He's in pretty bad shape, but he's gonna make it. Oddly enough, he was walking to the bar, because he doesn't drive after he's been drinking. It's pretty messed up... Maybe I can get to it tomorrow before I head off to work.

He will be using the above diagram to achieve a constant out to power a siren, from a horn honk wire.

hi fellas
i believe it's my first post...i'm more of a reader and gone with the info i find.
however when i tried to find the 10K µfd capacitor i was completely unsuccessful.
if somebody could point me in the right direction i'd be so grateful.
i'm trying to wire up my marker lights to blink with my flashers.
i understand what i need to do but cannot locate these capacitors.
thanks

You want your side marker lights to blink with your Flashers? And you want the side marker lights to stay on constant when turning. Or do you just need a source for the capacitors?

a source for the capacitors is what i am after. i couldn't edit the post. i was not sure after i read it if i had worded it right. but yeah...if you can help with finding them that'd be great. i've searched fruitless. thanks
