How Does a Golf Cart Starter Generator Work-The Expert’s Narration

A starter generator is a kind of device that helps to turn on the golf cart engine and also charge the battery of the cart. Through this article, I will provide you some basic and essential information about how does a golf cart starter generator work.

The golf cart starter generator works in two ways; the starter portion cranks the engine, and the generator portion recharges the battery. When they get too short, the golf cart will not start giving the impression, and you should know that the starter generator has gone bad. You want charge golf cart batteries then read The Best Way How To Charge Golf Cart Batteries: Technical Guideline.

The Work of A Starter Generator:

When the gas pedal gets depressed, the starter cranks the engine over, and it starts to move on its own. The generator section of the unit begins to charge the 12-volt battery. The starter generator brushes are vital for this process.

A starter generator works on the principle that movement of a wire in a magnetic field induces a current in the coil.

The movement is provided by connecting the pulley of the starter generator to the main axle of the cart via a belt. This produces current, hence the name ‘generator’ in starter generator.

A starter generator performs the following functions in a golf cart:

1)        Starts the cart

2)        Charges the Battery

3)        Gives power to on the lights of the cart

4)        Can give a small power supply

What You Should Do if The Cart Get Bad:

Sometimes your cart may get worse, or it can stop working. Then you should know there may be a starter-generator that has got some troubles.

Here are some main signs to look for a check if there is a problem with the starter generator:

1. When you turn the key, the cart does not start

When you turn the key to start your cart, but nothing happens or hears only a clicking sound, there could be a problem with your starter or your battery.

Just turn on the headlights or interior lights. If they can light up well, be sure the battery is fine, and it is possible that your starter generator is bad.

2. Judging from ‘Time Taken to Crank’:

If it feels like it is taking longer than usual to get your cart cranking, it is an indication that your starter generator could be going bad.

Make sure it is not a battery problem by checking that the lights are turning on.

     3. Listening for noise:

If there is a ‘grinding noise’ coming when your cart is running, it is very likely that the gears in your starter are worn out and working improperly. This is the same noise that one hears when you turn the key on your vehicle that was already running

4. Starter too hot or smoke coming out: 

If the starter gets too hot within a short period of time, it is a very strong sign that something is wrong with it.

Usually, the voltage will also drop because of getting too hot. If smoke is coming out of the starter, you know it is over.

5. Pulley of starter not moving freely or rusted:

On looking at the starter generator, if the pulley looks rusted or does not move freely on moving by hand, this is a clear sign of your start going bad. You will have to change its pulley, and the starter should work.

However, make sure the rust is only on the pulley and has not reached to the starter. If it has reached, it is time to replace the whole starter generator immediately.

How Does a Golf Cart Starter Generator Work

You should know about how does a golf cart starter generator work to maintain your golf cart properly.

A starter generator is a mixture of two different engine components. The components can be found in lawn tractors, garden tractors, and aircraft.

The starter component generates the initial agitation, starting the vehicle, and the generator maintains the voltage while the cart is being operated. The function of a starter-generator has discussed below in details:

Voltage:

The starter generator initially enlists because of the direct current voltage sent from the battery of the cart or equipment.

Once the switch of the light is turned, it closes the contactor or electrical connection, sending voltage to the starter of the component. After sending the voltage to the starter, the component acts like a tiny motor. The starter turns, sliding or turning the engine.

At the same time, voltage is being sent to the spark plugs, which helps to blow the fuel inside the engine tub or turbine of the starter.

Starter:

The starter part of the component is a combination of a stator, windings, armature, and brushes. The armature is joined to wires wound in a circular motion making a field coil.

Then the voltage is sent to the coil, next into the brushes, and then to the armature. As the voltage flows through a series of field, a magnetic field will be created.

The voltage runs through various parts of the coil, by changing the created magnetic fields. As a result, the magnetic field rotates around the coil, and the stator turns by engaging the power plant.

Generator:

The generator section of the starter generator components provides voltage to all the electrical components of the cart. Each electric feature of a cart requires some amount of voltage to run.

The lights, PTO, emergency hydrant instrument, computer systems, and other electronics found on aircraft or tractors must be charged. The generator sends the proper amount of voltage to the each machinery while maintaining enough voltage to run all the components at the same time.

Troubleshooting:

The starter generator has some common problems that can be improved with these accumulations. The tool can create a certain amount of power supply because it has one coil, which can limit the features available on a cart.

Regular automotive and tractor generators have cooling fans on the instruments, but the starter generator is enclosed, which can cause it to get overheated easily. If the brushes wear too much and the interior instruments get out of the round, the brush can bounce, because of a break in the electric flow.

If electricity gets interrupted, the electronic machinery will work occasionally. Bearings and other components can wear very soon if the starter generator begins to get overheated.

How to Do Bench Testing of a Golf Cart Starter Generator:

This test will work for SKU 15421N. This is an off-vehicle test, so you need to remove the starter generator from the golf cart. Before removing the starter generator, you should make sure that the battery is charged and working properly.

What You Will Need:

• Battery Jumper Cables

• 10 Ga Jumper Wire

• Working Battery (Take one from a working vehicle if possible. battery must have 12.5 volts. DO NOT use a jump box)

• Vise to Hold Starter (You can have someone hold the starter if you don’t have a vise)

Be sure that while you are testing the starter generator, that you keep any loose clothing, jewelry, or your fingers away from the pinion gear as its spins.

Bench Testing Step By Step

To complete a bench testing of a starter-generator, you should follow the instructions below:

Step-1:

Place your starter generator on a gripe or call someone to hold it carefully.

Attach the 10-gauge jumper wire from F1 to A2.

Step-2:

Attach the 10-gauge jumper wire from F1 to A2. Attach the negative (BLACK) battery cable to the negative terminal on the battery. The other end of the battery needs to be attached to the A1 stud on the back of the starter generator.

Step-3:

Attach the negative black battery cable to the negative terminal on the battery. The other end of the battery needs to be attached to the A1 stud on the back of the starter generator. Attach the positive red battery cable to the positive terminal on the battery. Touch the other end to the F2 stud on the starter generator.

When the positive cable touches the F2 stud, the motor should start to spin in a counter-clockwise rotation. If the motor spins, then it is working correctly. If the motor fails to spin, then it is defective and needs to be replaced.

Step-4:

Attach the positive or red battery cable to the positive terminal on the battery. Touch the other end to the F2 stud on the starter generator.

When the positive cable touches the F2 stud, the motor should start to spin in a counter-clockwise rotation. If the motor spins, then it is working correctly. If the motor fails to spin, then it is defective and needs to be replaced.

Frequently Asked Question:

Question: Can a starter motor be used as a generator?

Answer: Yes, you can use a starter motor as a generator. Cars no longer use generators. They use alternators, which produce AC output that is converted to DC.

A starter motor is designed for high torque and low speed. It is designed to draw a very high flow of current for a very short time.

Question: How can I know if my starter is bad on my generator?

Answer: By noticing some signs, you could be sure that the starter is bad on the generator. Here are the main signs to look for to check if there is a problem with the starter generator:

1) When you turn the key, the cart does not start.

2) Judging from ‘Time Taken to Crank.’

3) Listening to noise.

4) Starter too hot or smoke is coming out.

5) Pulley of starter not moving freely or rusted.

Final Verdict

A golf cart starter generator plays a vital role in running a golf cart. It helps to start the cart, to on the lights of the cart, and also helps to charge the battery of the cart and to supply power to the cart.
