Help with fuse, The 3rd one just went :( Options

[Starcraftjunkie]

Well, it took 3 fuses for me to figure out it's not my fault (directly, at least).

I decided to take out the mp3 deck and replace it with the stock toyota celica 2 din cd/stereo/cassette deck. New harness, etc etc.

But when I turn on the stereo, the courtesy door lights/map light/clock goes off.
This turns out to be the 10A mini fuse being blown.

At first, I thought it was being blown when I was moving wires and harnesses around, but after this 3rd time, I'm pretty sure the fuse goes right when I turn on the stereo.

Any ideas? I'm sorta clueless about this type of electrical stuff.

How do I fix a bad ground?

On the back of the deck, there's:

- a rectangular plug for the harness coming from the amp under the climate controls
- a larger round plug in the corner (I'm assuming for the power?)
- a smaller round plug beside that (for the antenna)

What do I need to do? I have 4 10A fuses left and I'll like to solve it before I have to buy new ones. haha..

That 10A fuse sure screws a lot of stuff up. Besides the door lights, dome light, and clock, it took out the control for the low beams. So when I flip the headlights, it automatically triggers the highs. :|
