Bosch Alternator Repair Manual
Alternator problems manifest themselves in various ways, depending upon the particular failure. Still, using a few simple tests at home that show you how to test an alternator, how to inspect a battery, if necessary, and check a drive belt will help you pinpoint the cause of the problem. These tests only take a few minutes, and you don't have to remove the alternator from your car. For the main tests, you'll only need a digital multimeter. However, if you have to test the battery, you'll need a hydrometer tool as well. It's a good idea to buy the service manual for your particular vehicle model so that you have the electrical specifications and particular procedures that apply to your car model. The manual will pay for itself if you plan on doing some maintenance and simple repairs yourself.
You can get an inexpensive aftermarket manual at your local auto parts store. Also, Amazon offers many of these repair manuals at low prices as well. NOTE: Some auto parts stores will charge your battery and check the operation of your alternator free of charge.
If you don't have a digital multimeter or a hydrometer and can't buy the tools now, you can take advantage of this to establish the condition of both system items at once. Here is an outline of the content you'll find in this guide. Skip to a particular section if you want to check or test it first. Alternator Problems Troubleshooting 1.

Checking the Drive Belt. A red-battery or ALT warning light on your dashboard coming on warns you of alternator problems. But headlights that suddenly loose brightness, dimming dashboard lights, or a battery that looses power, may also indicate charging system problems. Still, you need to confirm the alternator has filed before you replace it.
These next tests will help you check charging system operation. Alternator Output Test One of the most common problems on an aging alternator arise from worn out brushes. But a charging circuit blown fuse, a broken fusible link, a failed diode in the alternator's rectifier assembly, even a worn out bearing will affect charging system operation. So, using a digital multimeter, let's start by checking how much voltage your charging system is delivering.
1.1 Measuring Battery Base Voltage NOTE: If your battery is discharged, try to borrow a good battery for these tests. That way you'll quickly check whether the charging system is the one causing trouble. Otherwise, you may want to concentrate on checking your battery first. So go to the battery tests outlined below.
Set your voltmeter to a setting of about 20 on the DC voltage scale, and connect the probes across the battery posts following the proper polarity. If your battery is fully charged, you'll read about 12.6 volts. Make a note of your reading. You'll use this voltage as a reference point for the next two tests. 1.2 Measuring Charging System No-Load Voltage. Start the engine and let it idle. Ask an assistant to keep engine speed at about 1500 rpm.
Turn off all vehicle accessories. Connect your voltmeter across the battery terminals. Make a note of the voltage reading. You should get between 0.5 and 2 volts above your base voltage. Any voltage higher than this will indicate an overcharging condition. The problem may come from the alternator or the electrical circuit.
However, if your voltage reading remains the same or slightly lower than base voltage, the charging system isn't working. You may have a poor connection in the charging system (check that connectors and wires are in good condition and making good contact), a failing alternator or voltage regulator, which usually you'll find mounted on the alternator's case in modern vehicles. Visually inspect wires and connectors, and refer to the 'Checking the Voltage Regulator' section below, if necessary. 1.3 Measuring Charging System Load Voltage If the charging system passed the previous test, you need to see if the charging system produces enough power for your battery and the different electrical systems. This time, ask your assistant to start the engine, and increase and hold engine speed to about 2000 rpm. Now, turn on all accessories like radio, air conditioning, headlights, and wipers.
Connect your voltmeter across the battery terminals. Make a note of your voltmeter reading. Subtract the base voltage from your load voltage reading — this is your charging voltage. Your charging voltage should be 0.5 higher than your base voltage. Otherwise, you may have poor circuit connections (inspect wires and connectors), or a faulty regulator.
Continue with the section below. Checking the Voltage Regulator If the charging system didn't pass the No-Load or Load test, check your alternator's voltage regulator. Charging systems come under different designs. So consult your vehicle service manual to test the voltage regulator. These tests include a 'full-fielding' test, which is nothing more than bypassing the voltage regulator, and it's not as hard as it may sound. Your manual may also asks you to check a fusible link for continuity and inspect fuses related to the charging system and tell you their locations. NOTE: On some modern vehicles, the powertrain control module (PCM) — the engine's and transmission's computer — regulates voltage rate fed through the alternator.
With this type of system in place, your service or repair manual will tell you what type of tests you can do in your own garage. 2.1 Replacing a Voltage Regulator If your tests determined that you have a bad voltage regulator, check your local auto parts stores or online for availability. In many alternators the voltage regulator mounts on the outside of the case and you'll replace it in a matter of minutes. Keep an eye on small nuts, screws and springs. They are very easy to lose. However, if your alternator is four years old or more, replace the whole unit. The different components in your alternator will soon start to show signs of wear.
You'll save more on a new or rebuilt unit now than having to deal with more alternator problems later on. If you have the luxury of waiting a couple of days or more before replacing a bad alternator, check for prices online, you may find a brand new, quality alternator at a lower price than a good, rebuilt unit from your local auto parts store.
Checking for a Bad Diode Usually, a bad alternator diode will cause your headlights or instrument panel lights to flicker or dim and, sometimes, drain battery power overnight, or in minutes. To check for a possible bad alternator diode, switch your voltmeter to a low setting on the AC (alternating current) voltage scale. New holland tc33 manual. With the engine running, touch the meter probes to the battery terminals.
Your voltmeter should read 0 AC volts. Any amount of AC voltage would indicate a bad diode, so you'll need to replace the alternator. In addition to alternators, batteries are also a common source of charging system problems for two main reasons. First, if your battery sees little use because you don't drive your car often, the battery sulfates.
Although the battery still provides good voltage, it won't deliver the correct amperage. Second, if you use your car regularly, you may forget to service your battery regularly, which may result in low electrolyte level or corrosion buildup, leading to poor electrical flow. Inspecting the Battery Check the battery terminals. If they are corroded, this might be your problem. Corrosion prevents proper electrical flow. If necessary, disconnect the terminals and mix a tablespoon of baking soda in 8 ounces of warm water.
Apply the solution with a soft brush to the terminals. Clean the battery posts as well. If your battery has filler caps, clean the battery top and carefully remove the caps using a screwdriver. Check the electrolyte level.
Add distilled water to the cells to bring up the electrolyte to the correct level and recharge the battery if necessary. If you need to recharge the battery, and you are going to recharge it at home, make sure to follow safety precautions. A charging battery produces hydrogen gas, which is highly explosive. Charge the battery in a well ventilated area away from appliances with open flames like dryers and water heaters. Also, follow the instructions that come with your battery charger, specially when connecting and disconnecting the battery.
Performing a hydrometer check The hydrometer test will let you know whether your battery is fully charged, needs a charge, or has failed. A hydrometer is an inexpensive tool.
Buy one at your local auto parts store, and then check this article on using a hydrometer. Basically, a reading below the 1.265 mark usually means your battery needs charging. A difference of 25 to 50 points between one or more cell readings means your battery is defective. Can a drive belt cause charging system problems? Yes, if the belt has become loose, or you haven't changed the belt at your manufacturer recommended interval. Check the belt's tension and condition. The belt will fail to operate the alternator if it's too loose, or it's stretched due to years of service, causing it to slip over the pulleys.
A slipping belt will usually produce a squealing noise. Visually inspect the belt for cuts, tears and missing chunks. Also, check the alternator pulley and the rest of the pulleys the belt rides on. If one of them is misaligned or not turning freely, it'll damage the belt as well. Your service manual will offer you a good procedure to check not only your belt, but proper operation of the belt adjuster and idler pulley as well.
You'll deal with alternator problems more effectively if you know how to test alternator output voltage and conduct other related tests. Still, don't overlook the obvious. Sometimes, there's where you need to start troubleshooting.
For example, when doing a quick visual inspection, you may notice corrosion on the battery terminals (preventing power in and out of the battery) a wobbling drive belt while the engine is running (worn out or damaged belt) or a noisy alternator (failing pulley). And keep in mind that, more often than not, charging system — and other systems — problems arise from lack of adequate maintenance. Using your best judgment and the tests outlined here will help you pinpoint the cause of your charging system problems faster. I have a faulty transmission.
It has a solenoid problem except the solenoids keep om changing which one is the faul. Ive replaced the solenoids in the valve body but still same problem. I have checked and replaced wiring looms inside the gearbox and checked the plugs.
All is 100% except that fault of it changing its problem solenoid. I have a sneaky suspicion that it is the voltage regulator sending incorrect voltages to the TCU as it sits in the valve body.
