Alternator/Battery/Electrical Problems!???! 1992 T-Bird V6, NEED HELP-URGENT!

Ok, i'm 17 years old, and I have a 1992 T-bird V6, the engine is in awesome condition, ok body, and everything.
It has 172,000 miles, and runs awesome.
But, the other day, i noticed my Blinkers didnt work, and, my heat, didnt work.
They work when i turn the key a little bit, but once the engine starts, it stops working. Both of them, i thought maybe it was the alternator, because the car died friday night on my way home. And the battery was dead.
So I went out, and bought a new alternator (Duralast Gold series 80 Amp) for $60 ( i got a discount from a friend at Auto-Zone). Anyways, I took my battery in too, to have them charge it up for me. I took it all home, put them both back in, and it ran fine, but I still didnt get any blinkers, or heat when the engine was started. I thought it was all fine then anyways. I thought about the fuses, but that would make it not work at all, all together.

Well, I was on my way home last night, and the car died again. So, i dunno what it could be...


Think there is a short somewhere, making it power from the battery, and not the alternator? Or a Multi-function relay switch? Or is there something in the ignition?

I need some help, and I need my car running by tomorrow...lol...


THANKS!

replace your ignition switch the electrical part. mounted on steering calumn

alright, I talked to a few people today, they told me the same thing, or I may have gotten a bad alternator. So im gonna go have my new alternator tested, and if it turns out OK, ill replace the ignition switch.

Thanks a ton!!

Or your battery is toast and will not hold a charge for period of time, typical of a dead cell. Have the battery load tested once fully charged. If it cannot sustain over 9.6 volts, it's time for a new one.
