Power issues in 03 Mustang
I'm new to the carputer scene and the MP3car forums. I've been thinking about building an in-car computer and have, after years, finally resolved myself to "just do it".. but I am running into some issues in the final stages of integrating the whole project into the Mustang.
I have tried to keep the dimensions of the project as small as possible so I can fit it all into the double-din sized opening in the dash, vacated by removal of the stock Mach460 head unit: it didn't sound all that great, and it didn't have any aux in anyway.
The problems that I am running into are as follow:
a) it is not possible to power up the computer until the car has been running for a certain amount of time (varying 5-10-15 minutes), unless it was already driven in the past 2 or 3 hours. If I try to turn it on, the computer will momentarily turn on and the immediately shut off again.
b) sometimes if I roll up/down power windows completely, once the window comes to its stopping point, the computer shuts off.
Other than those issues - once it's up and running it works very well.
Here are the system specs:
- Insight Solutions P4-ITX motherboard (integrated audio, video, lan, etc)
- Intel P4 2.0GHz
- 512MB RAM
- IBM Travelstar 20GB hard drive
- Delorme Earthlink GPS
- (PW200M - 200W power supply)
- Xenarc 700TS
I learned the hard way that one of those amplifier capacitors will not solve these problems, and am now in the market for a new psu as well. Fortunately that's all that fried.
Cans someone give me some insight as to what exactly is causing the issues? I was doing some searching, and it would seem that I may need a tank circuit to resolve this...? Am I on the right track?
Has anyone else experienced these issues? Any suggestions?
