I was going to hookup to relays to an actuator. Question, if i have my actuator being fed a constant 12volts will it end up burning the actuator? Like if i make it so that its always got a positve 12volts on one side and ground out the other side would i ruin something or drain the battery? Thanks, i know its a dumb question but it would save me a lot trouble and time.

yes if you had constant ground on one side of the actuator and constant 12v on the other side you will kill the actuator and drain your battery. Actuators are meant to be used momentarily. What is it your trying to do with the actuator?

I'm trying to make my actuator open and close all in one pulse. So basically when i hit the trunk pop on my alarm, my actuator to the trunk will unlock and lock. Your probably wondering why i'd want that. It is complicated to explain but i'll try. Basically the "unlock" portion of the trunk would make it pop up. Without the "lock" portion, the trunk will go down but the mechanical latch won't shut. Reason is that while the actuator is in the "unlock" position, the motor inside is in the "closed" state. Because of this "closed" state, the trunk's mechanical latch is to weak to pull the actuator back the the original position. I know that if i can make the trunk actuator go open and closed, this will solve all my problems. Thanks for the help!

nice challange. Lets start with the basic circuit. Pick which one best fits your alarm.

thanks for the nifty diagram wizard! Maybe i''m not understanding right but is this assuming i have 2 negative outputs available? Sorry for my ignorance. I wanted to baiscally have the polarities swap sides all in one button push using just one negative output from alarm (since thats all i have). From what i understand, please correct me if i'm wrong: The diagram you proposed makes it so that if i push the button once, it will unlock, push again and it will lock right?

This diagram has a seperate lock and unlock signal. Here is why I picked this one. You only need one function by what you say. unlock function. Now we figure out how to hook the constant to momentary circuit to the other side for automatic locking action. I need to know if we have a Negitive pulse or a positive Pulse. ------------- John DeRosa (Hotwaterwizard)

i have a negative pulse from my alarm. Thanks Wizard!

Here is what I came up with so far. The Diode is a standard diode like 1N2001 1N2002 1N2004 it stops the coil from dammaging the capacitor and resistor.

i have no idea if that will work but i trust your opinion because of all your other posts that i have read. Btw, i know the squiggly thing is a resistor and the one to the left of it is a capacitor, but what is the one to the left of that? a diode of sorts? if so, what rating diode should i get?

I answered your Question while you were looking. How strange is that?

BTW, can you explain to me what grounding the resistor and capacitor like that does?
Thanks! i'm very curious how it works.

Oh, went to the electronics store today and they told me that there is no such thing as a 2500uf capacitor. Did i get screwed around with :(

2500 uF does exist. If you were screwed around it was from the guy at the shop you went to! https://www.mouser.com/search/ProductDetail.aspx?R=TVA1318.3virtualkey61320000virtualkey75-TVA1318.3 TVA Axial Electrolytic Capacitors 50V 2500uF Mouser Part #: 75-TVA1318.3

You could also try two 1000uF capacitors in Parallel to get 2000 uF That will give about a 1 second Delay.

I went to 2 different places and the best they had was 2200 16v. Does it matter what voltage capicitor i get? Should i use 2x 2200 16V ones? i'm asking cuz the pack they have is a 2 pack. Thanks Wizard! Yeah those people told me that the 2500uf was an oddball one...jerks!...

This is not rocket science. I was guessing at the value anyways, try one 2200 uF first and see if it works. Pay attention to the +on the capacitor. If you get it backwards it will be an electric party popper. The voltage rating does matter, never go lower than your working voltage. ------------- John DeRosa (Hotwaterwizard)

Hi Wizard! I did everything as per the diagram but found that i had to reverse the diode around to get it to work. Maybe i'm just confusing myself or didn't originally understand the diagram but this worked like a charm! yay! i finally have remote trunk release! using just a plain jane actuator that one would use for a door.

OOPS! Here is the correct Diagram. Just showes I am not perfect. LOL ------------- John DeRosa (Hotwaterwizard)

Also, just to confirm, i used a 2200uf 50v capacitor and it worked just as well!
