6 symptoms of bad micro switch on golf cart [with fixes!]

The golf cart can get stuck in a certain mode if it has a defective microswitch. For instance, it might continue to go in forward or backward even if you try to change the direction.

After having the Symptoms Of Bad Micro Switch On Golf Cart, it is advised to either have your golf cart’s microswitch checked and replaced by a competent technician or to go to the manufacturer’s literature for specific troubleshooting instructions for your golf cart model.

How to Inspect a Bad Micro Switch on A Golf Cart?

Anyone can perform the fault-finding process for microswitches because it is so straightforward. You can use the advice listed below to help you right now. Simply apply them to your micro switch as needed, and everything will be good.

Step-1: Split the Plastic

To ensure you have an extremely clear vision, plastic components need to be separated.

In other words, you’ll be able to examine how the microswitch’s component parts were put together. You can accomplish this by using a drilling tool.

Step 2: Examine the removed parts

You can inspect each component one at a time after taking images of your microswitch.

You must verify that the parts are properly positioned and make the necessary contact. Sometimes a microswitch will malfunction if one of its parts is faulty. Replace it if you detect any flaws. It will resume functioning as a result.

Step-3: Wipe the components

There is a good likelihood that dirt will start to gather in microswitches after they have been operated for a while.

You can soak the parts in water fifty percent green diluted for about sixty minutes if you don’t feel comfortable cleaning them yourself. This method of cleaning is more efficient and can get rid of 80%–90% of stains.

Step-4: Reassembling

Once you have examined the components and determined what might be wrong with this microswitch, it is imperative that you reassemble it according to the manufacturer’s specifications.

This stage can be accomplished without any special effort. All you have to do to figure out how all the parts have been assembled is to look at the prior photographs.

Symptoms of a bad micro switch on a golf cart

In general, microswitches are quite dependable and last a very long time before needing repair or replacement. Let’s have a look at the symptoms of a bad microswitch.

1. A faulty mechanical switch

When a golf cart’s mechanical switch becomes stuck or fails to turn over when it is charged, the golf cart may not behave as intended.

For instance, one sign of a bad micro switch is a situation in which the forward/reverse switch is turned to the forward position but the trolley does not move forward.

Therefore, it is essential to check the micro switch to make sure it does not become stuck and impede the golf cart’s functionality.

2. Poor Wiring

Golf cart microswitches’ wiring is susceptible to fraying or other damage, which can cause connections to short or fail. The electrical signals will not be transmitted by the microcontroller, and the golf cart will not react as intended.

Ensure that the wiring is installed appropriately. The breakdown of the overall structure, which affects power flow and causes the golf cart to perform improperly, is one of the obvious signs of a malfunctioning micro switch with defective connecting wires.

3. Unsuitable Voltage Readings

Unsuitable voltmeter readings are one sign of a defective golf cart microswitch. Switch the voltmeter to continuous or OHMS in order to evaluate the voltage supply since both instruments display a similar power flow.

Finding the switch’s 36-volt side is the next step. Direct labeling on the switch’s body is required. Typically, this is the input side. Determine the micro switch’s positive and negative connections.

To prevent power flow, tape the positive connection to the exterior of the golf cart or another grounded component.

Similarly, handle the negative terminal and connect the voltmeter probes to the correct connections. The voltmeter ought to show continuity, indicating that current is passing through it.

The voltmeter failing to register continuity is a sign of a malfunctioning microswitch. Check the mechanical switch, a tiny metal component and flip it to the other position; this should restore continuity to the micro switch.

4. None to Start Action

On many golf carts, like the EZGO golf cart, the solenoid is powered by a micro-switch located on the accelerator pedal.

One sign of a broken micro switch is when a golf cart ceases to respond to the accelerator pedal, failing to accelerate to the appropriate speed or, if it remained stationary, failing to move off.

When this happens, the micro switch has to be troubleshot to make sure it is put back in working order. Damaged connections may be the root of this issue, so these must be fixed or replaced. It can also be necessary to reset the microswitch.

5. Uncontrolled Changes in Speed

Some golf carts, like the EZGO RXV and EZGO TXT, can have defective microswitches. Uncontrolled speed variations and the inability to maintain a constant pace while driving are two symptoms of this defective microswitch.

If these signs are present, it is advisable to check the accelerator pedal’s micro switch to make sure it is operating as intended and to address any potential issues.

6. Starting and Stopping

A golf cart’s propensity to stop and restart while running is one clear sign of a malfunctioning microswitch, especially in the case of the EZGO model.

Testing the golf cart’s micro switches and having them fixed if necessary is the first step to take in such a situation. Using a voltmeter to check for any defective connections and to verify the voltage continuity are both advised.

Bypassing the micro switch on a golf cart is one method of testing the micro switch. To do this, a jumper wire is used to transfer energy from the 48V positive terminal to the solenoid’s tiny positive terminal.

The wheels will start to spin after switching the key to the “on” position and applying the accelerator.

Once the golf cart is in service mode and the back wheels are raised to access the underneath of the golf cart, this should be done.

When the starter is jumped, the key switch should turn when it is in the Front or Rear position, indicating that the micro switch was at fault.

How to Repair ezgo micro switch symptoms?

Your golf cart has to have a defective micro switch fixed as soon as possible to prevent further harm. A defective microswitch may be repaired using the three-step process below.

Track the Microswitch

Utilizing the user handbook as a guide, determine where the micro switch is located in your golf cart. Rewire the micro-switch if it is not in the desired position.

Check for Consistency

If the micro switch is in the desired position, perform the previously specified continuity test by attaching a voltmeter across it.

Change or Remove the Microswitch

If the micro switch doesn’t pass the continuity test, you may either have a professional repair it or, if you don’t want to pay the money right away, have it bypassed.

To bypass the microswitch, adopt the following steps:

• Lift the rear wheels of the EZGO golf cart to access the underneath, then switch the golf cart to service mode.
• Connect the little positive connection on the solenoid to the 48V positive terminal using a jumper wire.
• Press the accelerator after turning the cart’s key to the ON position.
• Verify the wheels’ regular rotation.
• If the wheels won’t turn, test the jumper connections once more and repeat steps 3 and 4.
