Draining battery hi i had a quick question, i have a 95 mazda 626 and im having a problem with the battery draining. I had the alternator replaced and actually had the old tested and both turned out fine. Before when i drove and then come to a stop the abs light would start flashing and the rpms would drop and the car would shut off, normally it would start right back up but would repeat this a few times. Now the battery is draining completely, when i come to a stop if the car shuts off it will not start without a jump. Ive had a few people look at it and were all stumped! please help!! :) thanks! Lisa.

It may not be the same problem But, My Jeep would quit until it cooled down and then I could start it and it would run again. Did this on and off for weeks. Turned out that it was the sending unit in the fuel tank. Cold fuel, no problem. warm fuel it would shut off. Cost me $500. Hope this helps, Good Luck

sounds like the starter, i dont think its siezed the motor in that short distance. try and hit the starter with a hammer or something with someone turning the key at the same time, it should start with acouple trys. if it does than u need a new starter.

Replace your battery when its being tested there not testing it under a heavy enough load. A battery could have a dead cell in it and still show good on the charger. I've had that problem a few times.

It can be as simple as the funny belt tensioner on the alternator!

I hope you got a simple volt meter to check the voltage.


12.8-13.6V is a health battery.

Get someone to help you to put tension on alt. belt.

If it does not look good then change it.

Double check all belts.

The should not give over 1/2" I like to keep them 1/3" of less.

Tighten all connections.

Pull spark plug cap one at at time to check for corrosion.

The coil can cause a lot of problem.

Spend time to grounding and secure all coil boot.


Good luck

I would first have the alternator checked by an auto electrician to ensure it is working correctly and is providing the correct volume of current. It may be faulty and when driving you will be drawing battery power instead of power from the alternator to run the electrics. This will drain the battery.

Alternators do not last forever and if you are still running the original unit it is likely to be on it's last legs and you will need a replacement unit.
