    Help Me With Relays

    alright.. so i jsut got back home... i go to my garage to see my baby...

    i get in.. notice it is kinda dark in there... i put my key in, press the clutch, and turn the key... and nothing happens.

    my carpc drained my battery.

    i expected it since ive been gone for a month, but then i fully charged the battery and the next day i go to drive it and its dead again.

    i know its the CarPC, i disconnect it manually (unplug the PS) and cover the end w/ eletrical tape so i dont blow up.. but i need an on off switch for not just the igintion wire... but the actual power wire.

    so... i decided to do that... now after bout 5 minutes of thinking about it.. i dont think a switch will be able to handle the load that the carPC has.. and thus i went to relays..

    now... heres my problem... i have no idea how to wire relays.

    so.. help...

    Hey, all I did was I wired a switch for my master ignition wire. so I could by hand turn it off. But I don't think it's drain safe. I'll have to see myself if it's going to work.

    EDIT: Small brain fart. You are draining the battery while the car is off. Hmmmmmm. What PS are you using/how are you powering your carPC. Are you using Hibernate/Standbuy/shutdown?

That wire is low power, not like the main power form the battery. You do take it from the battery, right? Well, that is off track, sorry. Just put it in the switched/accessory wire, and you will be fine.

    That's exactly how I am doing it.

    And don't forget, if you discharged your battery low enough, it's possible that it's internally damaged and won't hold a charge correctly again.

    Not if its a deep cycle dry cell.

    If you are placing your system into standby then you know that 5v is always will be on. If you are placing the system into hybernation everything is off if you set your bios to S3 mode. Also opus new power supplies have the ability to disconect itself if the voltage in your vehicle drops below a certain level.

    So, which PS are you using, and are you using standby/hibernate/shutdown, or what

    S3 (Suspend to RAM) applies to the suspend/sleep function. Hibernation is as good as shutting the pc off, as it dumps the memory contents to an image file on the HDD, and then shuts off. S3 basically shuts the machine off and uses just enough power to keep the ram refreshed so it can come back almost instantly.

    I am using opus power supply. The power supply disconects at 10.5volts. Currently I am using standby set to S3 but I recommend hybernation.

    I have 2 deep cycle dry cell batteries with a isolater. The pc is connected to the 2nd battery. If that battery drains for some reason the main battery will still be charged to start the engine. When the engine is off the batteries separate from each other. When the engine is running they join as 1 and share the loads. This setup is because of my high current audio system.
