What is a generator belt and how much does it cost to get fix?

My battery warning light came on and my owners manual says that it could be the generator belt. The car starts up with no problem. How much does this normally run to get replaced?

Could be as simple as adjustment if no air conditioning on vehicle. Little more work if it does have A/C. Worse case scenario, it's not the belt but alternator/generator. Check belt condition & tension & go from there.

If its the belt that is slipping then a new one is inexpensive, perhaps $10. The labor to it in can be a bit worse as some other belts or parts may need to be loosened or removed to get the new belt installed. Other problems can cause the symptom you describe including failure of the alternator itself. Rebuilt alternators are available if its that. You may also have a corroded connection between alternator and battery

I have a '99 dodge grand caravan se, while in park the abs light came on, the battery light came on, and the check engine light has been on,


Looks like you have a few issues there.

1. The battery warning. This is indicative of a weak battery and if your battery is 3 years old or more I would replace it.

2. If you have a weak battery this can trigger other warning lights in the vehicle, typically the ABS warning but sometimes other warning lights as well depending on the electronic features in the car. If you replace the battery this should correct the battery warning and most likely the ABS warning if both of these warnings appeared at the same time.
Normally, once the ABS warning is displayed the anti lock braking system(ABS) will be shut down. Whilst your braking will be normal, if you brake too hard and lock up your wheels on a slippery road there is no ABS assist to prevent the brake lock up which you have when the system is working.

3. If the alternator on the engine is not generating sufficient power and thus not charging the battery at all, or very little, you will likely get a battery warning light. I don't know if your 1999 vehicle has a warning light to indicate a faulty alternator or not.

4. Check Engine Light.
You suggested the CE warning has been showing up for a few days and before the battery and ABS warnings popped up.
The CE warning can be caused by dozens of different engine issues.
The vehicle needs to be scanned with the appropriate scan tool to see what fault codes the onboard computer is generating because if you have a CE warning light there will be fault codes generated 99% of the time.

Once these fault codes have been pulled the mechanic can start to diagnose the cause of the problem or problems. Each engine fault code your car's computer is generating can be caused by different types of problems so it is important that they diagnose the issues correctly. Otherwise your Check Engine light will remain on as long as the causes are not identified and fixed.

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.

Car won't start. it tries to turn over, but just doesn't .battery replaced several months ago so it's not that. The red "GEN" light pops up. Is that the generator signal? Manual doesn&


Interesting. They haven't used generators in over 50 yrs.
But yes that was the warning light for the generator.
If you have a volt meter that would tell you what the system is doing.
If the engine will not crank, and the battery is fully charged, you would need to check the connections at the starter for voltage and ground.
And the red warning lights would normally come on until the engine starts.

My battery warning light came on and my owners manual says that it could be the generator belt


In 1997, they have a serpintine belt, if this belt fails, you lose power steering as well. this would make the vehicul hard to steer. the belt is at the front of the engine. It also drives the water pump, over heating would occur. If these other simptoms are occuring, you have a belt problem. There are to other posible worn items. Alternator, and or battery. If the vehicul is starting it is not you battery. The alternator, should put out around 14 volts. hope this helps.

1998 ford escort altinator two bolt or three bolt? engine light is on brand new battery and the battery light is on . car just died when driving waited 7mins and it started .is it the altinator


check with volt meter. 12 volts with engine off. Should be 14 volts with engine running if alternator is working.
First, clean battery posts and cable ends. Then check owner manual for fuse locations and blown fuses. There is a large 100 amp fuse in box under hood.

Is the battery lamp lit on the dash?

Looks like 3 bolts. please rate when done

Electrical power system service required.....ABS warning light, generator warning light, brake failure...car stalled and wont't restart


usually caused by failed generator. Fix the generator and other lights will also extinguish. The car should jump start, but will not stay running without a charged battery. Recommend removing the generator and take to parts store for testing. Would you like instructions for removing generator?

How to disable seatbelt alarm on 2003 F-150?


There is a procedure in the owners manual on page 110.

BeltMinder activation and deactivation procedure
1. Turn the ignition switch to the RUN (or ON) position. (DO NOT START THE ENGINE.)
2. Wait until the safety belt warning light turns off. (Approximately 1–2 minutes.)
• Steps 3–5 must be completed within 60 seconds or the procedure will have to be repeated.
3. Buckle then unbuckle the safety belt three times, ending with the safety belt unbuckled. This can be done before or during BeltMinder warning activation.
4. Turn on the parklamps/headlamps, turn off the parklamps/headlamps.
5. Buckle then unbuckle the safety belt three times, ending with the safety belt unbuckled
• After step 5 the safety belt warning light will be turned on for three seconds.
6. Within seven seconds of the safety belt warning light turning off, buckle then unbuckle the safety belt.
• This will disable BeltMinder if it is currently enabled, or enable BeltMinder if it is currently disabled.
7. Confirmation of disabling BeltMinder is provided by the safety belt warning light flashing four times per second for three seconds.
8. Confirmation of enabling BeltMinder is provided by:
• The safety belt warning light flashing four times per second for three seconds.
• Followed by three seconds with the safety belt warning light off.
• Once again, the safety belt warning light will flash four times per second for three seconds.
9. After receiving confirmation, the deactivation/activation procedure is complete.

Alternator problem?


check battery voltage with engine off. should be @ 12.5v
check with engine running at about 1500 rpms. It should be @ 14 volts. If yes, it is ok. I think you are ok.
Please rate higly if htis helps

your system is more sophisticated than Sars can handle.

here's how it works.

The charging system consists of a generator which generates current to supply the vehicle electrical system and maintain the battery in a charged condition.
The generator is driven by the accessory drive belt. For additional information, refer to Section 303-05 . When the engine is started, the generator begins to generate alternating current (AC) which is converted to direct current (DC) internally. The DC current is controlled by the voltage regulator (located on the back of the generator), and then supplied to the battery.
The charging system voltage is controlled by the powertrain control module (PCM). The generator charges the battery and at the same time it supplies all the electrical loads that are required. The battery is more effectively charged with a higher voltage when the battery is cold and a lower voltage when the battery is warm. The PCM is able to adjust the charging voltage according to battery temperature by using a signal from the intake air temperature (IAT) sensor. This means that the voltage setpoint is calculated by the PCM and communicated to the regulator by a communication link.
The PCM simultaneously controls and monitors the output of the generator. When the current consumption is high or the battery is discharged the system is able to increase the idle speed.
To minimize the engine drag when starting the engine, the PCM controls the generator. The generator does not produce any output until the engine has started. The PCM then progressively increases the output of the generator.
The PCM controls the operation of the charging system warning indicator in the instrument cluster. The PCM is therefore responsible for turning the warning indicator off after the engine is started and illuminating it under fault conditions (when the generator is not generating the correct amount of current with the engine running). The warning indicator will also be illuminated by the PCM at key - on engine off and stall conditions.

Warning bell won't stop sounding


Section 13-09: Gauges, Warning Devices — Chime System 1996 Windstar Workshop Manual
DESCRIPTION AND OPERATION Warning Chime Systems Three distinct sounds are used to indicate the area of concern. Seat belt warning generates 1 chime per second
key-in-ignition generates 2 chimes per second
headlight on generates 4 chimes per second.
Key-In-Ignition Warning The key-in-ignition warning will sound when the driver's front door (20125) is opened with the key in the ignition switch. It will continue to sound until the key is removed, the front door is closed, the ignition switch is turned to START or the vehicle speed is over 24 kmh (15 mph).

Safety Belt Warning When the ignition switch is turned to RUN or START from OFF or ACC, the chime will sound for six seconds or until the safety belt is buckled.
  • The safety belt warning indicator lamp (10C859) will activate for 60 seconds or until the driver's safety belt is fastened. Both the chime and lamp activate at the same time.
Anytime the ignition switch is released from START and returns to RUN while the safety belt lamp or chime is activated, the safety belt warning lamp or chime will remain activated until either the timing sequence has been executed, or the safety belt is buckled.

Headlamp Switch On Warning The chime will be activated if the headlamps or parking lamps are ON, the key is not in the ignition and the driver's door is opened. The chime will sound at a rate of four per second.
