89 toyota camry battery issues

if it died suddenly you may have left a light on. otherwise it cannot hold enough charge to start the car because the battery is old, or your alternator does not put out enough voltage to keep the battery charged.

Everything starts with having the battery tested. The charging system can only be tested when you have to good, fully charged battery.

try starting the car and while running disconnect the negative battery cable,if the car still runs turn on the head lights,if the car dies the alternator is weak. I think its weak and can charge the battery as long as the lights are off,but cant keep up when theyare on. so if drive most of the time in the day time you are ok as long as you dont have to start the car too many times. when you drive with the lights on and the engine slows to an idle like when you park the car dies. make sense?

Most auto parts stores offer free Alternator testing takes 5 mins. if the Alternator is good and will hold a charge,then your problem sounds as if it is a spark plug/ fuel mixture issue,,check plugs and plug wires.

Stop by any good parts store (Autozone, Advance, etc...) and have them do a FREE charging system test and LOAD test your battery. You'll find the culprit.

13.5 volts is not an unreasonable voltage. How do you know it's not taking a charge with the new alternator and new battery? I might have it checked at the battery retailer using their starting/charging testing machine.

Have the battery and alternator checked by a mechanic or auto parts store. As it is, it would seem your battery needs to be replaced, but if your alternator is bad then your battery may be good and you would just need to replace the alternator and charge the battery.

Yes you have a charging problem more then likely it is the Alternator

I am almost certain that it is a faulty DIODE in your alternator.. You can check this out for free by taking your vehicle to a Checker/Schucks/or Kragen Auto, or Auto Zone. Just request a Charging System Test. If it is, in fact your problem, you will need to puchase a new alternator.

Similar problem for my 89 camry. It ended up being my in tank fuel pump that had died.
