'89 Ford Probe battery dying?

[Kinson]

It has a brand new alternator... A brand spanking new battery in it... I had it rigged so my front radiator fan would cut on as soon as the car was started, so I undid that hoping that maybe I had wired it wrong, but that wasn't it...

Let it sit for a couple days and the battery has barely enough juice to run the app's. I had a sub/amp in the back, and I took those out also thinking that the amp might not be turning off properly...

I've checked anything and everything that might be a problem caused by myself, and I have no clue!!! I need to fix this cause I can't drive the car EVERY day to make sure the battery still has enough juice to start the car...

Anyone experienced the same problem??

I'm also having a little problem with 3rd gear around 2500 rpms, the gauge will shoot up to like 3500 then back down and up again a few times till it settles at 3k...

Thanks in advance !

Hello,
I'm new to the forum and came here looking for advise on the problem that you have.
I have a 94 probe doing the very same thing, it's driving me nuts. Mine seems to do it more frequently when the weather is cooler or cold. In the summer I never have this problem. Same senerio as yours, you have to keep driving it every day and I've been through several batteries with this. Anyway, thought I'd let you know that I'm working on it, and if I find it I'll let you know. If you get anywhere with this please let me know.
Just post a reply or email me at jfm888@ipa.net. Good luck
