The fuse had blown, so I replaced it.

Now the empeg comes on and stays on permanently, as in it never goes off. The Rio Car now starts up, but as soon as it boots up, it powers off.

This is a '92 Tercel I'm trying to get everything working in. (Yeah, my stereo is worth more than the car. At the time I was looking at new cars when I had money, then the market went south, etc.)
