i just got a new altenator new battery fues box and harness but my battery is still draining how do i fix that in a 91 ford escort gt

Put a digital voltmeter on the battery and see how much a draw is on it. The service manual for '95 says that a draw of up to 0.05 volts is normal. Make sure you disconnect the light under the hood first, as well as turning off any other lights that might be on.
If the DVM shows a draw greater than 0.05 volts, start pulling fuses under the dash until you find the circut that is draining the battery. If the fuses under the dash don't stop the drain, then do the same to the fuses under the hood.
If you find the draw after pulling a fuse, all you need to do is find the problem with that circut. (Bad light, light socket, ground, etc...)
If there is still a draw on the batt. after pulling all the fuses, I would take the battery back and have it tested, as it might have an internal short. Just because it is new doesn't mean it's good.
Good Luck

Exactly where did you get your "new" alternator? Is it really "new" or is it rebuilt.

new altenator at autozone im getting a volt meter tommarow thanks

 

[pextor]

new new or rebuilt new? check your receipt. it's more than likely a reman, which is not new.

Plus it's from Autozone, which means that it's probably already defective. Get a good one from NAPA.

so far so good got a voltmeter i drove my car to work to autozone and home its been sitting for about to hours in its reading 12.58 volt in the batter so i dont know my be the altenator needed to be charged im going 2 check it about 8 or 9 if the battery is full i fixed the problem

What's the voltage when it's running?

 

[91stevengt]

when running the voltage is 13.04 but when off it goes down a .01 volts every few minutes cant figure out why and i did check all the fues and still didnt find any volts while off

u have some kinda of draw....maybe a relay? my gf's moms van did that and killed the battery alot. relays are kinda the same as fuses just different but they can draw power 2.

For a brand new alt. that voltage seems a little low. I have no idea how old the alt. is on my GT, but it still puts out over 14 volts at idle.
I would get the car to AuotZone and have them do a load test on the charging system. Sounds to me like you got a bad battery or alternator.
I always have them test the new alt. before I walk out the door with it. It makes them a little angry, but it saves me from wasting my time.

whats the voltage at 2000 rpm? you cant really guage a charging system unless its spinning faster.... it really should be at least 14 with no accesories or ac running, and shouldnt drop below 13 with everything running like wipers, flashers ac, and headlights and radio and whatever else you can turn on



get this issue straightened out first, then get the battery load tested.... sometimes when a charging system isnt performing right a battery can discharge quite quickly or even become damaged very fast. after you know the alt and the battery are good and still have the issue. then you need to check for parasitic draw


which is a little more in depth on how to do it right. so pretty much when you get to that step you cam pm me and I can explain better how to do it the right way

14V at idle is a bit optomistic. Sometimes you have to be above idle to get up to 14V.

heres where its draining and how much stop on inside fuse box stop 20A 13.35 hazords 2.35a and door locks 13.35 how do i fix and can i just pull fuses i dont even have door locks on my car there old school pull up push down

You would need a wiring diagram to see what's on the Hazard circuit and trace it from there.

I know this is a little late, but here is the proof that my alt. charges @ over 14 volts at idle:

? i'm not sure what you're saying here.

but i'm going to guess you disconnected the positive battery cable and put your multimeter in line between the positive cable, and the battery positive post, and read the amperage of the parasitic load with the car off. then you started pulling fuses to see what made the amperage drop back to around zero to find what system the problem is in. then you went and looked at the wiring diagram in that system to figure out exactly where the problem might be.

if that isn't what you did, do it and get back to us.
