SOURCE: home wind generator early model chev alternator need schematic

Ok I'm going to try this from memory...last time used it was a few years back when wiring up a big boat. Large (B+) wire goes from battery to large terminal on alternator back. Facing the rear of the alternator, top spade connector on alt goes to a switch (there was supposed to be a resistor in that wire, but I never used one) switch connects to (+) on battery. Terminal on right goes to the (B+) terminal on alternator. Alt case is ground.
I can't find my old chiltons electrical book but that is how I remember it.

SOURCE: lost car keys to T-reg Ford Mondeo

Don't do that yet, You have two best options, 1st. before you go though all that, hoping Toyota still keep the key code back from 1998 other wise you have to go with 2nd option. take your registration or title to the dealership and ID card showing them your the owner to that car. any toyota dealership would be able to cut another key for that car with the vin number, its allot cheaper and less head ache replacing it; will cost couple of bucks. 2nd call a lock smith, they will come out and cut the key for about 100-150 bucks using the the trunk unit and you still be able to use the keys for everything. Replacing your ignition will be much more and you have to fiddle and installing it. it not that hard but time consuming although i would make it my last options. If you have car insurance, some of them may have a lock out policy. they pay for the lock smith to come out and cut the keys.

I recommend getting an actual voltage, ampres check to see what the alternator is putting out, volts and amps. You should be able to get the charging, battery load test and the starter draw all tested together. That's where I would start.

SOURCE: What is the stock Alternator AMP output for 2003

You have two options If the truck is stock then the 95 amp is fine but if your running aftermarket accessories then you would benifit from the 130 amp. All the alternator has to do is keep up with the load being applied.

Does a 1998 Isuzu Trooper alternator charge through the PCM to the battery?

No. In every charging system I have seen the alternator output is direct to the battery, however the control that regulates the alternator output can be performed in variety of ways.

You need to check the wiring diagram to discover how yours is controlled.

Most alternators since the late 1970's are self contained generators but there are recent developments such as smart charge systems that feature a certain amount of computer interference.

A rough idea of the system can be formed by the number of connections to the alternator. A "normal" machine-sensed setup requires only two wires - the output connection and a thin cable from the ignition/charging/battery light, though an alternator mounted in rubber bushes will also require a heavy ground bonding cable.

A few early setups also needed a ground cable.

How to wire a12 volt dynamo on atractor

now if your converting a dynamo to a alternator then no problem ,on the back of a self exciting alternator is two wires to worry about ,firstly a big thick wire directly from the alternator to the large + terminal on the back of the alternator to the battery + terminal then as a self exciting alternator this alone will charge the battery like a lucas ACR type and the small wire from the dynamo which is the warning light control can be connected to the small terminal on the alternator with no modification.Now later types are controlled by the cars ECU unit so these type are not suitable but older cars from the early 90s will convert and be usefull with no problem any alternator with a output exceeding 30amp will suffice for a older vehicle that was a dynamo as most were 25 or 30 amp output and limited current usage like 45/55 watt headlight bulbs compared to modern cars so this conversion is relativly easy but if your really good reduce the size of the pulley used and a different V belt to accomodate so its charging on idle .Yes i fully aware that the pundits will say that you need a relay and a fuse and whatever but it will work perfectly ok when done simply this way you can always push start the vehicle as the alternator will start to produce current so long as a ignition light lights up this is enough to get you going ,well with a proper car with a manual gearbox you can anyway

You might have had a external regulator, which would still be wired to the vehicle and fighting against the new alternator. It should be a black box bolted toward the front. It should have a 4 wire plug that will be labeled on the terminals "I A S F" . Remove it and you should be good.

2000 ford zx2, battery light keeps coming on/off, had alt checked (good), battery checked (good), could this possibily be a wiring issue (short/bad connection)?

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.)))

1965 amp meter

what to do first is remove the regulator then un tape loom of regulator wires some of the wire go to the old generator remove the ones linked

now there should be one wire that goes back to the engine loom that was going to the reg or gen

now with someone helping get them in the car turn on the ignition on the gen light should be on yeah
now u place wire on + side of battery and ask if light go out if it does then u got it

86 Tercel 2wd wagon won't charge it's battery

clean battery terminals ,bring battery to be tested after charging, after reinstalling battery run car and test alternator output it should be a minimum of 13-14volts if it is under 13 replace alternator , use a voltmeter set on 12 volt 10 amp dc to check the wire to check is located on the back of the alternator covered with a rubber grommet of course hold negative wirw on volt meter to ground and touch red wire to big terminal on back of alternator while car is running should have 14 volts or at least 13 volts
