I just got done installing my alarm, a Delta Pro 5005. Everything works just fine except for the door locks. I have aftermarket actuators, so they are just 2 wires. Correct me if I am wrong, but both leads should rest at ground, then when one sees 12+ it activates the actuator one way or the other. Well, I hooked up my relays exactly like it said on The12Volt.com:

Everytime I try to hook it up, it blows the fuse. The first time it wasn't fused and ended up burning a path inside the alarm which I had to repair. Another strange thing that happens is, when I arm (lock) OR disarm (unlock) the alarm BOTH leads from the alarm give a ground signal. Why would they do this?? Shouldn't only one give the signal so that the actuator knows which way to go?? I know that can't be the problem though because it blows the fuse as soon as it is hooked up, not when you arm the alarm. Any help would be GREATLY appreciated fellas. TIA!!

The leads should NOT rest at ground. That would just cause a short circuit. Dont do any extra connections other than the ones shown in that diagram. I dont know what you did to make them rest at ground though...? I dont know why the alarm is doing what you say when arming and disarming though.

I was just told that they would rest at ground in this configuration. The relays are hooked up EXACTLY like the diagram, with nothing extra. I have NO idea why the alarm is sending ground through both leads during locking and unlocking. Also, I have tried using the 12V+ coming from the alarm on the door lock harness AND a seperate 12V+ from the fuse box and it blows the fuse either way. I am so confused!!

That was it! But my alarm is still sending negative to both leads during lock and unlock. Any idea why this could be happening?? Also, anyone know where I can find relays. Radioshack doesn't carry them and the ones I have are the only ones that Autozone had. Any other good places to look? Maybe a stereo shop would sell me some. Thanks for the helpm guys.

I get how it is supposed to work, I think you misunderstand what is happening. BOTH leads give a negative signal during both lock AND unlock. So therefore, it will be sending a positive signal to both leads of the actuator. Maybe that made more sence.
