  • a few unanswered questions

    hello im a newb to car pc's, a friend turned me on to the idea and now ive been researching. i have a 95 ford branco with a high end battery, and believe i will use a power inverter to power my system. i haven't bought anything yet, but i have been looking to a shuttle system, with an indash touch screen. i kind of have an idea of how to run the cables and audio speakers, but the power is the most confusing part. I know i run the inverter to the battery and then the inverter to the pc. my question is how do i hook up the power to the pc to make it turn on and off with the car without it just cutting off power, i know about start up and shut down controllers, but i don't really understand how to hook it up to the computer. can someone please clear this up with me with links or a simple explanation (im not an electrical engineer)

    thanks is advance

      inverters are messy. For the price of a quality inverter, you can get a dc-dc that has a SDC built in.

      A SDC simply takes constant 12, switched 12, and ground. It has a timer, and when the switched 12 comes on, it sends the 12 constant through. 12 constant is where the power is being drawn from. then after 12 switched goes away, a timer activates, and after some time, it shuts off the 12 constant.

      So that then goes to your inverter if you must.

      Or you can buy a M2 on eBay for $50 to $80 and it will be efficient, have a sdc, amp turn on lead for no thump, and 2 levels of controllable off (soft and hard times).
