Alternators are a key component for many Clark forklift models. Thanks to this component, many Clark lift truck models can carry out their material handling function without completely depleting their electric battery power. But, even though the majority of alternators for Clark forklifts are built to be strong and durable, they will eventually wear out and need to be repaired or replaced over time. When that time comes, it's best to be prepared. That's why Lift Parts Warehouse wants to share what you need to know about Clark forklift alternators and how and when you should choose their replacements.
What is the Function of a Clark Forklift Alternator?
An alternator is a device whose main function is to transform mechanical energy into electrical energy. So, when we talk about "Clark forklift alternators," we're referring to those alternators used in Clark lift trucks to produce the electrical power needed to operate their main operational functionalities. Most of these alternators for Clark forklifts consist of a rotating shaft, called the rotor, that spins inside a housing. The housing contains a stator, which is a stationary set of coils that generates a magnetic field. As the rotor turns, it cuts through the magnetic field and induces an electric current in the coils. This current is used to charge the battery and power the electrical system.
In many Clark lift truck models, a large part of the electrical energy stored in the battery is used to activate the starter that will run the engine. So in some way, the alternator keeps your Clark lift truck alive while the engine runs. Clark forklift alternators supply electricity to most forklift accessories, and they're responsible for charging the battery. If the alternator doesn't work properly, it can lead to many problems that will affect how well the forklift works. This could eventually force the forklift to be taken out of service until all these problems are fixed.
Do All Clark Forklifts Have Alternators?
Although there are many models and types of Clark forklifts, the truth is that not all use an alternator. Clark forklift alternators are used specifically in those Clark lift truck models powered by an internal combustion engine. Once the engine is running, turn its main shafts. Through one or several belts, the mechanical energy of this shaft can be used to start up many devices, among which the alternator is one of them.
On the other hand, in Clark electric forklift models, the entire vehicle operation relies completely on the electrical energy stored inside the battery's lithium cells. These models use batteries of such dimensions and capacities that allow them to work all day long without needing to be recharged.
The Main Clark Forklift Alternator Fault Symptoms
When Clark forklift alternators begin to show signs of wear, they can exhibit any of the following symptoms:
Dead Battery. The alternator is responsible for generating electricity to carry out the Clark forklift operations and recharging the battery's energy. If the alternator does not adequately perform this function, the battery will not be able to fully recover its electrical energy and will eventually be completely drained.
Dim or Over Bright Lights. When alternators for Clark lift trucks begin to fail, they can provide inconsistent voltage, causing damage to the rest of the electrical components. The first sign of a Clark forklift alternator failure is usually dimming lights or flickering electronics. If you notice these symptoms, it's important to have your alternator checked as soon as possible.
Trouble Starting. If you are having difficulties starting your Clark lift truck, it might be because the alternator is not working correctly. Alternators for Clark forklifts are responsible for recharging the Clark lift trucks' battery, so if you have one that isn't working well, your Clark forklift might not start up easily.
Burning Smell. If the alternator pulley is stuck, the belt will deteriorate due to the friction produced. When this happens, you will notice a strong smell of burning rubber. Similarly, when the alternators for Clark forklifts are overworked, they may provoke a burning odor. An overworked alternator tries to push too much electricity through its wires, causing them to heat up unsafely.
Unusual Sounds. Clark forklift alternators are devices made up of several elements. When some of its internal parts break for any reason, it will compromise the integrity of the alternator and its ability to adequately generate the required energy. When this happens, it is usually followed by growling and unusual noises when the alternator is running.
How Do You Check a Clark Forklift Alternator?
Checking the condition of Clark forklift alternators is a simple procedure you can carry out yourself. With just the right tools and a little elbow grease, you will know if the alternator is working properly or not. The following instructions will tell you how to do it.
Park the Toyota forklift in a safe area.
Before starting the check, you must be sure that the lift truck is using a battery in good condition. Ensure that the battery light is on, and with the help of a multimeter, check the battery's voltage state; anything measured below 10 volts would indicate a defective battery.
With the voltmeter still connected, start the Clark forklift's engine and rev it to 1,500- 2,000 rpm.
Now recheck the battery's voltage - it should show more than 12.6 but less than 14.5-15 volts, indicating that the alternator is charging the battery properly.
If the reading is lower, there may be a problem with the alternator belt or pulleys. On the other hand, the regulator may be the problem if the measurement is higher than it should.
Now, use a clamp-on ammeter to test the alternator amperes. Clamp the ammeter around the positive output wire on the alternator. An average range should be between 4-20 amps. Anything above 30 amps may indicate issues with the battery.
Press the throttle to see the amp change with the acceleration.
Finally, once the engine is off, disconnect the negative terminal of the battery and measure the voltage at the alternator output terminal. If there are any volt signs, there may be a problem with the alternator itself or the charging system.
Alternators for Clark forklifts do not differ much from other lift trucks alternators, so if you still have trouble grasping how these devices are properly checked, we invite you to take a look at the following video:
