so i did a compustar 3000m alarm/remote start this weekend in a 94 honda civic ex and im having a problem with the power door unlock. The car is stock with power door locks. so the compustar has a (-) door lock out put and the civic has (-) door locks. i hook up the lock to green /white wire under the dash and it works great. here comes the problem.... I hook up the unlock wire to the RED / green wire and the doors unlock when i touch the wires together and then it will not unlock the doors. the switch to unlock the doors stops working.. How can i get the unlock to work. Do i have to switch the polarity of the wire and do to a different wire? If so what wire would i be going to ? Any help would be greatly appreicated! THANKS!

yes i am using a meter and sorry it was the GREEN/ red. the vehicle wiring diagram on this site says that is the right wire. it test correctly. it was part of the 2 pin connector that was taped to the back of the fuse box. do i need to convert the polarity and do the unlock to the door lock controller box? ok so that you know if you take the wire from the unlock and put it on the lock side it will lock the door. Is the brain box bad?

Disconnect the unit from the locks and check that both alarm wires go to ground when you press the lock and unlock on your remote.

sounds like you have the correct wires, have you tried two inline diodes, on occasions i've had this happen a pair of 1N4001 series diodes, bars bacing towards alarm always seemed to do the trick, this may also happen if your grounding is poor, just so you know, if all fails well, we''ll assist you in troubleshooting.

where can i get the diodes from? are those radio shack part numbers? i grounded the alarm to metal of the car i can try to move the ground to see if it works. Thanks for the help.

im gonna try moving the ground and im gonna try to diode isolate the wires if i can find some diodes. do i cut the wire and solder it inline to connect the wire back together where i cut it? i have never had to use a diode before. The help would be appreciated...

where you have the lock/unlock wire connected to the wires in the car, if you have not soldered the connection yet, undo the connection and insert the diodes between both wires, band facing towards the power lock wires of the alarm. of course this is going with the theory you have verified that the lock/unlock trigger wires are the correct ones.

so i tried the diodes today so that did not work. i need to get this car done. I do not know what the hell the problem is. Its really starting to bother me. The alarm came out of an integra and it had the compustar relay pack in it. I dont know what the deal was but the unlock doesnt work now and the customer really isnt happy. One more question on the shock sensor what is more sensitive the 1 or the 10? Where can i put the wires if i convert it to a positive output. What wires would i hook it up to is more the question. Thanks
Ryan... im starting to HATE compustar! I love DEI alarms staring to HATE COMPUSTAR!

You need to make sure the wire goes to ground when you press the unlock button. Set your meter to the Ohm selection. Ground one lead to the chassis of the vehicle. The other lead to the wire in question, while pressing the unlock button, the meter should read very near 0 ohms. It should only read this when the button is depressed. Not anytme the door is unlocked.

Stop your panic and read my earlier post.

the more sensitive setting would be ten. Also, that civic would have central locking, i can't remember civics of that age having a rocker control, the power lock module would be located in the driver door, the connections really are easiest here, in comparison to the back of the fuse box location, if your compustar has onboard relays then you can set it up to work the actuators, in this case you would only have to connect the driver door actuator and the rest is done, the actuator wires are RED / yellow and WHITE/ black i think, or you can check at the module in the door for the negative trigger, you really can't get any simpler, check with your meter to verify,

i tried that .. this car is loved hardcore. moved the ground like 5 times nothing makes it work. what wires would be positive on the power lock module? the black and White? i need to get this piece of doodie done so i can move on with my life. does anyone have a wiring diagram for a compupack?
Posted By: t&t tech

do you have a meter? also post your wiring diagram for the compupack, i might be able to tell you which does what.

As howie and idiot told you earlier.....Make sure that you are getting a ground output from the alarm wires WHEN YOU PRESS the corresponding lock/unlock button ONLY. Lock wire gives you a ground signal ONLY when you press the lock button and the unlock gives you a ground signal ONLY when you press the unlock button. Read idiot's post...he explains how to do it. If you do not get a ground output then there is something wrong with the brain.

i did that and the unlock has negitive power all the time. So is the brain bad or is the ground for the alarm is not good enough? that is why i want to convert polarity of the wire.. But is there a option possibly that makes it not pulseand makes it a solid output cause the last car had the compupack in it. (converts polarity so you can use it on +door lock cars.) I do not have a wiring diagram to the compupack that is why i asked if anyone had a wiring diagram laying around that they could upload and help a brother out. I am no trying to be mean to anyone but i checked everything. The unlock wire has a negitive output all the time that is why when i touch it to the unlock input on the car it unlocks the doors.. So should i try moving the ground around to see if it corrects the problem? im at a loss. Lets say the brain is bad how would i get it warrantied or a new brain? Im not a certified compustar installer however i am a certified DEI installer. Will they warranty the brain if im not a certified installer. What else should i be able to do to make this thing work. Or should i just make the customer buy a new dei alarm and just all it a day. The car does have problems though like the car will only redline at 5500rpm when factory is 6500rpm. With the chiped ecu the car should rev to 8500rpm. So should i not feel so bad and tell the customer that it just isnt gonna happen .. I dont know anymore.

Changing polarity for the locks will not help you in anyway because the locks are negative. I'm pretty certain that your ground is not the problem...you've tried different spots with the same result so we can eliminate that as a cause. the only other thing it could be is the brain, electronics do fail and that seems to be the only explanation left. The fact that it's a continuous ground and not a pulse on "activation" leads me to suspect the brain. How long was it in the other car before you removed it? is there a second unlock or possibly a disarm wire? if you really want to stick with this unit then you'd have to test all the other wires coming from the brain and see if another wire possibly gives ground when you hit the unlock button.....yes, test EVERY wire since you don't have a wiring diagram. Not sure about the warranty, call compustar and ask them. If you're straight up with the customer...tell him/her everything you've tried to try to get this to work, they should understand.....bad brain! ------------- ...half of the truth can be worse than a lie. <----Roger Russell said that..

i will try the second lock unlock output or the disarm wire..
thanks for the help
