Yesterday as I was going down the interstate, my battery light came on. Well, it was doing anything that I could tell, but tonight my lights inside would dim and my heater would slow down, then later the lights would return to full brightness and the heater would start blowing regular.

I did the keydance (95 RS), and this is what it did:

1
pause
2
pause
4
pause
1
pause
5
pause
5
pause

I checked the code 24, and it said that it was the TPS get to high or to low a voltage.

The car would also stay revved up around 2k or 3k, and sometimes it would just bob up and down.

Would the TPS make my batt. light come on, and make the lights go dum like that, or do you all think that the alternator is going out too?

your code is 41 it said "Generator field not switching properly"
check items is "Harness and connector / Alternator"

code "12" always show up at the first time and "55" is end of error code

^^^^ exactly, good job! looks like its time for a new alternator. might i recomend the one from here, its only a bit more than a factory replacment and has a much higher output (in case you plan on any stereo mods in the future):

VERY fast shipping and friendly customer service as well. ;)


edit: forgot to add....you might want to take your battery into autozone, etc. to have it checked out, it might have gone bad as well in trying to compinsate for the low voltage.
