Electrical Problem
Hey rexers
I went to start my car yesterday and as soon as i turned the key i heard a low 'boom', and everything dimmed. The engine didnt crank and all the electronics didnt work right. I jump started it and let it warm up for about 15-20 minutes, drove it around for a little while and brought it back. When I was driving it i noticed that everytime i hit the brakes the panel lights dimmed, the battery gage jerked down and the rpm gage jerked up. This also happened when using other electronic applications, like the windows. Turned it off and immediately all the lights dimmed again. Obviously it wasn't able to crank again.
I want to say its the alternator... but what was that 'boom'? Is there like a big fuse somewhere that could have burst and made that noise? Any other thoughts?
whoa! that took me longer than i expected, sorry.

Sounds like an alternator to me... Lots of places will test both the alternator and the battery for free. (Advance comes to mind... as I like them :-)
Do you have a voltmeter? If so, you could check the voltage while the car is running and it'll give you a pretty good idea of if it's the alternator or not. (Should be around 16, I believe, while the engine is running- but don't quote me on that)

although it could have been an internal cell divider bursting, shorting two of them together.
