Tell me how I went wrong...

I wired up a relay from constant to momentary output today to allow for automatic door locking once the ignition is in the on position.

The relay worked just like it was supposed to when tested, but for some reason, it didn't work when I hooked it up to the driver door switch.

Lead 86 was fused from a switched ignition source in the drivers door.

Lead 85 was grounded with a 1K uf capacitor and 10K resistor wired in parallel, to allow for 1/2 second output. Had a diode between 85 and 86 as well...cathode was on same side as 86.

Lead 30 went to the negative (ground) door lock wire from the door lock switch

Lead 87 went to ground

I know that if you ground the door lock wire (black and white) located in the door lock switch, it will lock the doors. But for some reason the relay didn't want to work the way it was supposed to. I checked all the leads and I have power and ground...but the damn relay didn't want to work.

I tried another relay by itself, just to see if it would engage with my current leads, but it didn't work either, but when hooked up to the battery, it worked fine.

What is going on

 

Surely somebody can help...(in other words, bump)

 

Nevermind, I figured it out

I just need to create 2 momentary relays, one for locking, and one for unlocking, and I should be all set...

I had to re-do some wiring, so now I'm set for AUTO LOCKS!!!!

I'll keep you posted...

 

johnnyb_s,

Great work!!..
Make sure you post some schematics and PICS
