okay, i hooked up my crimestopper alarm so that the lock/unlock is not driver prioritized, so basicaly all the locks will open at the same time when you press the button, i used 2 relays and a 1.5Kohm resister it works but i think 1 of the relays is leaking current or something, it shows 0.25v on the mmeter. and i can see the "door ajar" light on in the gauge cluster but its VERY very faint which means that the relay IS leaking current. i was wondering if anyone else has this problem and knows how to fix it

any help would be appriciated!! THANKS!

Hey,
Interesting problem. But on what pin of which relay (lock or unlock) are you showing the voltage? The door-ajar is a different circuit than the door lock-unlock circuit. What makes you think these 2 are related?

The 0.25V on the relay may negligible and ignorable. Maybe the door-ajar light's always on b/c you've inadvertantly grounded the door-ajar circuit. Is this led always on?

You can place a diode across the coil terminals to eliminate any voltage leaks. But the door ajar light shouldn't have anything to do with the lock wires.

im not sure exacaly what is going on anymore, im way to tired to think lol i was working on the alarm for 10hrs strait!! i didn't even notice that much time went by.. oh well. Anyways, maybe its the alarm brain that is leaking voltage, but most alarms will go off if you open the door so the alarm is hooked into the door trigger,

i think it grounds when the door is open and +12v when the door is closed or somehting like that, bah i will use my multimeter and find out later... but fornow igotta re-adjust the sensitivity

The door pin shows 12v when the doors are closed. That's normal. They have nothing to do with the lock wires. The reason why your door ajar indicator is on because your alarm probably has illuminated entry. The alarm sends a ground signal to the dome light and you may see the indicator light at that point. It only happens when you disarm the alarm or shut off your car. It should shut off in about 30 seconds or so. Don't worry about it though, it's not going to harm anything.

when the car is armed its still on though, and i didn't hook up the dome light wire, only parking lights

Why are you using relays? Your crimestopper should have negative door lock outputs, most alarms come that way. All you have to do is wire them directly into the lock wire in the car. Take the relays out, they aren't necessary. That could be causing your problem.

i was following directions from another page on this site, it had a relay hookup table and i used that.. it works perfect with the 1.5K ohm resistor i ghetto'd together (1000ohm+200ohm+200ohm+100ohm lol), that light doesn't even drain the battery that fast..

You made it more complicated than you had to. Just run down to radio shack, buy a 1/4 watt 1.5k ohm resistor, hook it up, and you're done. My alarm keeps the door ajar light on very dim like yours, because of the illuminated entry. It completely shuts off after 30 seconds. I'd look over your wiring again if you're having that problem, or better yet, have someone else who's had experience installing alarms look at it for you. Again, those resistors have NOTHING to do with the door ajar indicator on your dashboard.

it works though.. so i guess i'll just leave it alone...

it is required to use relays on the 3rd gen. The 3rd gen requires a true ground signal, the 200ma output of most alarms is not enough.

here is a page with all the correct wires to use and locations for the 3rd gens.

thanks MSW, i actaully printed that page off and used it while installing.. very very helpful page!

Hmmm...not using any on mine and it works fine.

interesting, but there is a chance the outputs could burn over time. You sure there aren't onboard relays on your alarm? what brand/model is it?

JDMstuff

I'm using a Clifford Concept 600. There are no onboard relays. It's controlled by an IC that puts out about 200ma. I've done several installations in Mazdas with no problems using alarm outputs directly into the lock wire. Relays are definitely not necessary.
