If it ain't broke, don't fix it. Your charging system is working as it should.

2011 Toyota Avensis Strata Diesel Battery Light staying on.What causes this?


Battery light is (more accurately) also named charging light or generator light.
One side of the light is connected to the battery via the ignition switch and the other is connected to the alternator. When the ignition is switched on, one side of the light is at battery voltage and the other side at 0 volts and so the light illuminates but when the engine starts and the alternator produces a full output both sides of the light is at the same voltage and so no current flows and the light is extinguished.

Assuming there are no wiring or connection problems your alternator isn't producing a charge. Perhaps you didn't need a new battery...

What the charging volts should be on my 1996 chevrolet 1500 5.7L?


13.6v minimum on charge. Off load with the engine running it should peak no higher than 14.5v and sit around 14 ish.
Engine off, lights off and ignition off the battery should sit around 12.6v if charged, 12.8v if a really good battery.
After overnight standing the voltage should exceed 12.2v with no load and no less than 11.6 cranking.

What is causing the battery to drain?


Running the car will drain the battery it if it's not charging ! An if your charging light is on it isn't charging ! Did you check power an grounds on the alternator ? There is a single heavier wire on the back of the alternator, this should have battery voltage ! You may want to take this to a ASE certified repair shop !
Functionality
With the ignition switch in the RUN position, voltage is applied through the warning indicator I circuit 904 (LG/RD) to the voltage regulator. This turns the regulator on, allowing current to flow from battery sense A circuit 35 (OG/LB) to the generator field coil. When the engine is started, the generator begins to generate alternating current (AC) which is internally converted to direct current (DC). This current is then supplied to the vehicle's electrical system through the output (B+) terminal of the generator.
Once the generator begins generating current, a voltage signal is taken from the generator stator and fed back to the regulator S circuit 4 (WH/BK). This voltage feedback signal (typically half the battery voltage) is used to turn off the warning indicator.
With the system functioning normally, the generator output current is determined by the voltage of the A circuit 35 (OG/LB). The A circuit 35 (OG/LB) voltage is compared to a set voltage internal to the regulator, and the regulator controls the generator field current to maintain the correct generator output.
The set voltage will vary with temperature and is typically higher in cold temperatures and lower in warm temperatures. This allows for better battery recharge in the winter and reduces the chance of overcharging in the summer.
Battery Positive Output (B+) Circuit 38 (BK/OG)
The generator output is supplied through the battery positive output (B+) terminal on the back of the generator to the battery and electrical system.
I Circuit 904 (LG/RD)
The I (ignition) circuit 904 (LG/RD) is used to turn on the voltage regulator. This circuit is powered up with the ignition switch in the RUN position. This circuit is also used to turn the charging system warning indicator on if there is a fault in the charging system operation.
A Circuit 35 (OG/LB)
The A (battery sense) circuit 35 (OG/LB) is used to sense battery voltage. This voltage is used by the regulator to determine generator output. This circuit is used to supply current to the generator field (rotor). The amount of current supplied to the rotor will determine generator output.
S Circuit 4 (WH/BK)
The S (stator) circuit 4 (WH/BK) is used to feed back a voltage signal from the generator to the regulator. This voltage is used by the regulator to turn off the charging system warning indicator. The S circuit is fed back externally on external mounted regulator generators.

Triumph Sprint GT complete loss of all power


Hi, Anonymous before testing any electrical component in the Starting System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead acid batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter.
4. Bank angle sensor needs a reset or is faulty.
5. FOB battery low or dead.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand, clutch, neutral safety switch.
9. Security alarm needs a reset.
10. Starter relay, solenoid, starter motor or circuit wiring faulty.
11. Starter armature or field coils have failed.
12. Main fuse or circuit breaker may be blown or faulty.
13. Faulty ignition relay.
14. The electric starter is working but starter clutch has failed.
15. Check for engine trouble codes.

Draining Battery


Check the alternator. You can observe your interior dome light or the vehicle headlights as you rev the engine. If the light intensity changes with as the RPMs of the engine changes, then you have a faulty alternator.

When i rev my car up the charging light comes on for a split seconde when my lights are on my turn signals dont work and some times the lights will go dim when that happens i got to charge battry or j


First charge your batery and re- install it in the car. Turn on the ignition and with a multin tester check for voltage at the battery. It should read between 12 and 13 Volts DC. Start the engine, accelerate up to 2500 rpm and measure voltage. It should read between 13.5 and 14.5 Volts DC.

If the voltage at the battery is lower with the engine turned off, your batery might be bad.
If the voltage with the engine running is not between 13.5 and 14.5 volts, your alternator is bad.

After a 2 hour ride out yesterday in daylight,i always turn my lights on to be seen when returned home switched engine off opened garage went to start bike again and completely dead has a data tool duo...


Might have 12.67 volts, but not enough amps to crank engine or light the lights properly. Try putting a charger on the battery, bring it to a full charge. Next, put a load tester on the battery to see if battery is weak or dead cell. If battery checks good, check the charging system. With engine running at idle, put volt meter on battery-read volts, then rev engine to high idle. Volts should climb higher than idle reading.

Rs125x aircooled 2t single engine fitted in another frame, with ignition on the engine starts and runs fine, when clicked to second position,,,ign plus lights,,,,all works well including brake lamp, But...


I would say the ignition switch wiring is incorrect. The first possition should feed horn, brake light and ignition and position two will run the lights. So find the wire that feeds the horn and brakes then remove it from position two and connect it to position one leaving the lights on position two.
Hope that helps..

My battery light comes on dim at idle and turns off when i rev the engine


This is indication of the battery being in good shape and almost fully charged. The light on the dashboard is an indication that your dynamo is producing sufficient current, which increases when you rev up and the vehicle is no longer drawing any charge from the battery. On idling, dynamo produces less current, thus to keep the electrical parts running it draws a small amount of charge from the battery thus lighting the indicator is very dim. Do not worry. Everything is OK with your cars engine & battery...........sodeep
