Question about Toyota Cars & Trucks

1 Answer

Good day I have a problem with my car conquest 1.3 it shows that the alternator is working but when we remove the terminal the engine stop running.

We did all testing and we found the alternator is working, but is only the engine stop after removing the terminal. Please what the course of this. thanking you in advanced

To test the alternator , connect a voltmeter across the battery terminals , battery voltage should be around 12 vaults on a charged battery , if higher turn on the head lights for one minute to remove charge to 12 volts, start engine and rev to 2000 rpm, voltage should now be around 13.5 to 14.5 volts for a alternator in good condition.

You have to remove the belt.Also you can have it tested on the vehicle.Once you have the 2 bolts off and the belt the alternator should come off.Good luck.

SOURCE: Daughter called me ..car wont

it sounds like you have blown fuse to the Alternator.. I don't know what car you are talking about but they charging systems vary.. But if alternator isn't getting all the power it needs it won't charge. this should be checked.

good luck

Would an alternator make your car will not start


If your battery is fully charged, the car can start and run from the battery with no alternator at all. It might run 1/2 hr with no alternator.

A good test for the alternator is to start the car and then unhook one of the battery terminals. If the alternator is good, the car will keep on running without the battery. If the car turns off hen you disconnect a terminal, then the alternator isn't working.

But a bad alternator won't stop your car from starting...it will just not keep your battery charged or keep the motor running once the battery gets less than 12V

On my 91 ram 1500, 318 I take my battery terminals off while it's running alternator is Good brand new but it kills my truck when I take battery terminals off


There are much better, safer ways to test the alternator. You should never remove the battery when engine is running or when the key is in on. That old style method was before engine computers. It causes voltage spikes which can fry delicate electrical components, the computer and its many low voltage circuits, and the alternator as well.

Use a voltmeter (costs like $20), and check battery voltage-a good battery should read at least 12.5 volts. Then check battery with engine running. A good alternator should show 13.5 volts at the battery. Then you know the alternator is working. If battery is still same as when not running, the charging system is not working.

It is just possible that you have a bad alternator. Take it off and have it tested at a parts store for free.

Your battery is not charged and will need recharging. That is not your problem though. The alternator is not running the engine once it is started. The battery starts the engine, the alternator keeps it running and recharges the battery.

Make sure all your connections are clean and sound to the battery and alternator. Start your engine, with a recharged battery, although it may be too late for your old battery. remove the positive terminal. If the engine stops your alternator is faulty.

1997 eclipse has to be charged every day in order to drive


There seems to be a no charge state in this case. I recommend checking the charging system. use the procedure below to isolate this issue.

Wear protective eye wear and clothing and remove all jewelry when checking your battery and charging system. Jewelry is a good conductor of electricity and is not recommended. Most batteries wear out every 3 to 5 years and need to be replaced. Always replace your battery with an equal replacement battery to assure proper operation. Automotive batteries have a +positive terminal (red), - negative terminal (black). Electricity is stored in the battery and then supplied to the vehicle when the engine is not running. While the engine is running the vehicles alternator charges the battery for future use. (Note: never disconnect the battery while the engine is running. If the battery cable is disconnected from the battery a spark can be generated which can cause the battery to explode or a major electrical malfunction to occur.)

To check a battery surface voltage, remove the positive terminal protective cover. Connect the +positive side meter lead (red) to the positive side battery terminal. Connect the - negative (black) side meter lead to the negative battery terminal. With the vehicle not running and the car sitting over night the battery voltage should be between 12.5 and 12.8 volts.(You will need to use a voltmeter for this testing procedure)

The alternator is rotated by a drive belt driven by the vehicles engine while it is running. Electrical voltage and amperage are generated to recharge the battery and supply voltage to the electrical system of the car. The alternator is held in place with mounting bolts. There is a main electrical wire on the rear of the alternator that supplies voltage to a main voltage junction box. If your alternator is not charging properly, your battery will slowly drain down from operating all the electrical systems in your car and stop the car from running.(most non charge states will be the cause of a loose belt or a low tension rate, due to a mis-adjusted alternator. make sure you have enough tension in the belt for full rotation of the alt pulley)

Next, you will need to check the alternators output with the Amp meter.

Testing the amperage output of the alternator is good for measuring the amount (not the level) of voltage the alternator can produce. This test can be tricky because if the alternator is weak it can still show it as producing amperage. Which is good, but if the voltage is low, it will still allow the battery to go dead. To check the amperage output of an alternator an amp meter is needed. Once the meter is connected start the engine. Next turn on all electrical accessories and raise the engine idle to about 1200 RPM. The alternator should output the max amperage it was designed to produce. Example: a 90 amp alternator should output about 88 amps. Note: An alternator cannot sustain maximum output for long periods of time. If the alternator is forced to operate at maximum output it will overheat and fail. An alternator is designed to operate at max amperage output only for a reasonable amount of time.

((Connect the voltage meter lead the same way you would in a battery static voltage check, Start engine (do not drive) at engine idle the voltage should be between 13.6 to 14.3 volts. If not the alternator may need replacing.)))

Battery light will not go off


I am posting a generic reply to the "charge fail" lamp (that is the correct term - when the lamp is lit = the battery is NOT being charged) problems rather than a specific cure for the ills in your car.

I suspect a faulty alternator OR an inadvertent short to battery - potential of the wire leading from the charge fail lamp to the battery charging alternator. Please try the following tests (BE CAREFUL while working - you are working near the engine + v belts + fans etc. and a fully charged battery = can be very dangerous)

Locate the three terminals of the battery charging alternator. The largest terminal would be connected to the battery positive cable (may be red in colour). The second terminal could be labeled as "W" = this is the terminal generating a frequency proportional to the engine speed for the tachometer. The third terminal is the WL or D terminal. The Charge Fail lamp is connected from battery positive (via the ignition switch) to this WL/D terminal.

Turn the ignition switch on but don't start the engine. Observe the "Charge Fail" lamp glowing in the dashboard. Now remove the wire going to the WL/D terminal. The "Charge Fail" lamp should now stop glowing. If the lamp continues to glow, there is surely a shortcircuit between the wire from the lamp to the alternator.

As this lamp current is not going to the WL/D terminal due to the short circuit, the battery charging alternator is not producing very little or no output. Check if the battery terminal voltage rises when the engine is running. If the alternator is working correctly, the battery would be at 13.2 Volts with the engine running.

The confirmatory test is to rig a spare lamp (12V, 3 or 5 watt lamp in a holder) between battery + to the WL/D terminal - if that works properly (lit when the engine is stopped and off when the engine ir running), you can connect a new wire from the lamp to the WL/D terminal - do isolate the earlier wire completely from from lamp as well as alternator end.
Hope this helps. Write back if I have confused you further.....
