I'm trying to remove the car battery in my 1991

Sounds like the car is going into limp mode which does not mean there is a tranny problem. Take it and have it hooked to a code reader, you will need to find a garage or something because the cheaper ones that are sold in your local automotive supply stores dont read the trans codes. Another option is to turn head lights on with the key NOT in the ignition and take the negative cable off the battery, then remove the positive cable, wait 10 to 15 minutes then turn head lughts OFF, recinnect the positive THEN the negative battery cables. This will reset the on board ECM.

Remove EFI fuse or battery Negative terminal for 5 sec or more.

- Check fuses in the fuse and relay box.
- Check for loose connections and connectors.
- Wiring harness.
- Remove negative battery terminal for 10 sec and reconnect.
- ECM.

Remove battery negative terminal for 5 Sec or more. Reconnect the terminal back and start the engine. If the check engine light illuminates again, retrieve the error codes and freeze frame data for detailed check up and repair.

You have some alarm system activated when stay car two weeks? If your answer is yes, I suggest disconnected the negative cable battery when the car is not runing long time. Try it and send us your comments.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

That is a pretty high draw. You might want to try disconnecting the wire that goes directly to the starter and alternator. How are you checking the draw? Do you have your meter leads in series between your negative battery terminal and negative battery terminal.

If the vehicle is not equipped with an air bag, skip Step 1 and simply disconnect the negative battery cable. Also, disregard all instructions below related to air bags.

1. If equipped, disable the SIR system, as outlined in Section 6 of this manual.
   
2. If not already done, disconnect the negative battery cable.
   
3. Remove the turn signal switch assembly.
   
4. Remove the key from the lock cylinder. Remove the buzzer switch and clip.
   
5. Reinsert the key into the lock cylinder and turn it to the LOCK position.
   
6. Remove the cylinder lock-to-steering column screw, then remove the lock set.
   
7. If equipped, detach the pass key connector.
   

To install:

1. Install the lock cylinder, attach the pass key connector (if equipped), then tighten the lock-to-steering column screw to 22 inch lbs. (2.5 Nm).
   
2. Position the key in the RUN position and reverse the removal procedures.
   
3. Install the turn signal switch.
   
4. If equipped with the SIR system, properly enable the system, as outlined in Section 6 of this section.
   
5. If not already done, connect the negative battery cable, then check the turn signals for proper operation.
   

Remove the negative cable from your battery and wait 1 hour the car computer will reset, be carefful that your radio is not anti device, otherwise you would need the code to reset your radio which is a four number code.

Good Luck!

Hi there,

This response contains troubleshooting procedures designed to locate the cause of an overnight power drain resulting in a dead battery, It assumes the charging system is working.

The first (and easiest) test I run is on the battery.

When you are done using it for the evening, pull the Negative battery cable.

In the morning, re-connect it. If it's dead again, the battery need replacement. This does not necessarily mean you found the problem.

If it starts, the battery is ok. It's time to look for the power drain.

With the ignition off, ensure the systems that should be off actually are off. For example: does the radio still come on? Wipers? Etc.?

In the same vein, has anything new been installed lately?

The next test is a lot more tedious. You will need a test light, needle nose pliers (to pull fuses) and the proper tools to remove the negative battery terminal (again).

• Ignition off
  
• Remove the cable from the Negative battery terminal
• Hook one end of your test light to the Negative battery post
• Attach the other end to the cable you just removed
• Again, double check connections to recent installations (radio, GPS, etc)
  
• If it lights up very faintly, this is likely the normal drain of the clock. The brighter the light, the bigger the drain.
  
• Find your fuse box
• While keeping an eye on the test light, pull the fuses one by one. Replace the one just pulled before going to the next.
• When the light goes out (or dims), you will have narrowed the the problem to a specific system. Check the legend on the fuse box for the offending fuse.
  

At this point there are too many 'What if's'. Which system has the drain will determine the next steps to be taken.

This procedure will allow you to focus in on the problem area. Let me know what you find out.

Hope this helps

Mike
