Alarm Problems in 93 Civic

I just installed a Motorjoy GTO Patrol alarm/remote start system in a 93 civic lx. Everything appears to be working correctly except the door trigger. The dome.door trigger wire for the civic shows 1v with the door open and 13v with it closed. Could this 1v be causing the system to think that a door is still open? As a result the alarm will not engage with it thinking that a door is still open so the alarm function is sort of useless. The remote start works ok. Is there a way to go about fixing this or do I have a problem with the control unit itself. I would appreciate any information anyone has. Thanks

The door trigger switch is on the inside of the door by the latch. It's covered by a peice of rubber. If the connection is corroded and not allowing for a ground  then the alarm will think that the door is open.Jeff

True, but if the corrosion is not all the way through, there' still some connection to ground even through the rust.

All the switches seems to be grounding properly but there still is that 1V showing on the door trigger line. Is there another possible solution. The alarm Arms for approximately 10 seconds, then beeps three times and indicates a door opening on the LCD remote. I think my alarm grounds are good but could that possibly cause a problem if it is poor. All the other functions work on the alarm system though. This is a brand new system, could my module be bad already. I'm very confused and very disscouraged. Any more ideas? Thanks again

From dissarm state I can arm/lock. Opening the door does not trigger an alarm within those 10 seconds. I can also dissarm/unlock the car but the open door indicator still stays on, on the remote. I can remote start within those 10 seconds before the three chirps indicate an open door.

I've armed with myself sitting in the car. The alarm does not sound when I open the door at all. Initially when I tested the system, everything worked and when I first plugged in the harnesses, the system seemed to go through an initialization sequence. Once I knew it was working I wrapped up all the wires in electrical tape and found a good ground. This is where my problem started. Now if I unplug and replug the module, there is no initialization sequence and I have the aformentioned problem. Like I said I tested my wiring from the harness that is plugging in to the module and all of that checks out except this 1V on the door trigger. Other than that I am iffy about my ground and I'm worried about my module being defective. Any thoughts?

ok just went out and did as you said. I didn't have any results though. Took each switch out and "armed". The doors locked and for 10 seconds I crossed my fingers and...chirp, chirp, chirp.... dammit... Tried to ground each switch, each one set the dome light off but no alarm. I moved the alarm ground to a known good ground and nothing different... What else could it be? Am I just looking at a defective unit? I have a 1 year warranty but I bought it on ebay so I don't know how much thats worth. Hopefully if something is wrong than I can get a new unit. Any further comments or thoughts would be appreciated.

The (-) door trigger wire you should be testing is light GREEN/ red stripe in the driver's kick panel, and if memory serves me correctly, it is an 18 gauge wire in 14 gauge-thickness insulation.  This wire should meter 12-14 volts with both doors closed, and drop to ground when a door is opened.  You can also disconnect both/all of the door pins and test them independently, metering them while off of the car and supplying them  with ground from another source---i.e.- a jumper wire from a ground under the dash to the metal mounting plate of the pin.  Good luck!

What are you using for a meter? Is it analog? Sounds like it's just out of calibration. Your 1v is probably really 0v which would be ground when the door is open. Your 13v is probably 12v when the door is closed which is actually fine. Does your domelight remain on for a period of time (like 15-30 seconds) when you close the doors? This feature found on many cars will usually cause the open door indicator to come on with many alarm systems. The alarm thinks the door is open because that interior light is giving it the impression that the door never shut. If you do have the domelight delay, try waiting until it goes out and then arm the alarm. post back your results.Steve G
