PLEASE HELP FAST! Alternator problem???

Okay. Over the last 3 days I have been slowly installing a new alarm/remote start. Every time I do ANYTHING, a new problem suddenly arises that may or may not have to do with what I was working on. I suspect this does not, but all opinions are completely welcome.

I noticed the day before yesterday that my instrument lights, and headlights fluctuated when I revved the engine. This reminded me of my old 66 Mustang which had some electrical...oddities. Right before I bought the 94 ZJ 5.2 (about a month ago), the guy put a new battery in. I am tempted to call him and simply ask if he has had similar problems.

While working on my alarm, and while having had all the doors open and the brakelight switch unwittingly activated, the battery drained completely. So I had the car jumped and let it run for awhile. The battery guage did not raise to the halfway point it was at a few days ago. So I too the vehicle for a trip to the gas station, not only because it needed gas, but because I thought driving it would charge the battery better.

At the gas station, when I tried to start the car again, it did not want to stay running. I had to keep my foot on the gas, otherwise the tachometer would drop quickly past .5 and the vehicle would die. I eventually had to keep my foot on the gast and shift into drive. By the time I got home (about a mile), I could take my foot off the gas without it dying. However the battery guage still showed at 1/4 or less.

It SOUNDS like an alternator problem. But since I installed this remote start/alarm (a remote start which I have not tested successfully, I am worried it was something I did.

So, I have taken the fuses out of the two alarm wires that I connected to where the battery cable meets the Distribution Center, and will see how it is doing tomorrow. I really don't think this will help though.

Any thoughts? Any!?!?

To me sounds like the battery is almost going to die soon ! Replace the battery and go for a free alternator check at any Autozone or Napa Auto Parts Store ! Mine had the same symptom weeks ago and the problem went away when I installed a new battery !

Hope this helps !!!
