How To Fix A Blown Fuse On A Golf Cart

The golf cart fuses break to protect its electrical components from excess current, which would otherwise cause damage.

When a fuse blows in your golf cart, you should inspect the electrical components connected to that circuit to identify and resolve the problem before replacing the fuse.

Otherwise, replacing the fuse when you haven’t resolved the primary problem may not help but cause the fuse to burn recurrently.

In this guide, we shall take you through different aspects of the golf cart fuse and how to fix it after it blows up.

Let’s roll.

How a Golf Cart Fuse Works

A golf cart fuse protects the golf cart wiring and other electrical components from excess current.

It features a metal element, which has a low melting point, and has excellent electrical conductivity.

Therefore, when excess current passes through the fuse, its element detects the sudden surge, heats up, and then melts to break the circuit.

That way, it prevents the excess current from burning the other electrical components in your golf cart.

The Types of Fuses You May Find in A Golf Cart

The various types of fuses you may find in a golf cart include:

10 Amp Fuse

The 10 amp fuse in your golf cart is located around the solenoid. It protects the solenoid and its connections from excess current.

If the 10 amp fuse blows up, it can interfere with the golf cart ignition system, making it unable to start.

This fuse is likely to blow if:

  • You installed an intermittent solenoid in your golf cart rather than a continuous one: An intermittent solenoid needs some allowance to cool down before the next ignition. Using it continuously may end up blowing its fuse. You should replace it with a continuous solenoid to make your ride operational and allow for flexibility of use.
  • The wire insulation of the key ignition is pinched or broken: A pinched or broken wire insulation may break or interfere with the continuous flow of current and burn the fuse. 
  • The voltage regulator has a wiring problem: When faulty, the voltage regulator may hit the starting generator, causing the fuse to blow up. The other signs of a defective voltage regulator include flickering in parts of its wiring, dimming of lights, starter problems, dead batteries, etc.
  • There is a short in the wiring harness connecting the starter generator to the battery.
  • The connection to the battery terminals is reversed.
  • The golf cart ignitor is defective.

When the 10 amp fuse blows up, one or several of the above issues is the problem.

To prevent future fuse problems, you should inspect all the possible culprits for correction.

💡 Golfible Tip: For replacements, install the products from original equipment manufacturers (OEM) as they promise more life and quality than ordinary aftermarket products.

50 Amp Fuse

The 50-amp fuse protects the transformer and other charging elements when your golf cart’s diode or several diodes die.

You can find it at different spots on your golf cart.

On the other hand, the diodes may blow if there is miswiring in either the D-plug or the D receptacle.

So, it helps if you inspect the plug and the receptacle for correction before replacing the diodes and the fuse.

That way, you will prevent a 50-amp fuse from blowing up in the future.

60 Amp Fuse

The 60 amp fuse protects the main electrical components from damage during charging.

You can locate it on the battery post and the charger socket on the other side.

The 60 amp fuse may blow up if:

  • There is a miswiring in the charging port
  • The fuse is fixed in the high current circuit of the motor and is too low to match the same
  • The fuse is used in the power circuit instead of the charging circuit
  • The battery terminals are wrongly connected
  • The receptacle terminals are making contacts when the cart is in use 

400 Amp Fuse

The 400 amp fuse is located in the main battery pack’s positive or negative terminal. It secures the golf cart motor against power surges from the batteries.

It is likely to blow up if the power current coming from the battery surges beyond the current rate level.

So, Why Would the Fuse in Your Golf Cart Blow Up?

The fuses in a golf cart may blow up if:

  • There is a grounded or naked wire in part of the wire harnesses
  • There are loose wires in part of your golf cart connections
  • Your golf cart start switch has a dead short connection
  • The battery terminals are wrongly connected
  • The starter relay is defective
  • You had installed a fuse with a low voltage in a high-voltage circuit
  • The voltage regulator is faulty, and it is sending abnormally high voltage to the fuse
  • The solenoid is defective
  • If part of the connection from the key switch becomes too hot and burns the insulating plastic causing a shot
  • The starter generator is faulty.

How To Fix A Blown Fuse On A Golf Cart

When you realize that your golf cart has a broken fuse, you need to identify that fuse for replacement.

Additionally, you need to identify the cause of the problem to prevent the fuse from blowing up in the future.

Below are the steps to follow:

Step 1: Find the Service Panel in Your Golf Cart

In most golf carts, you can locate the fuse box on the rear fender, behind the battery on the driver’s side.

However, the fuse box location may slightly vary across the three main golf cart models, including Yamaha, club car, and Ezgo cart models.

We have discussed the fuse box location in each model to help you locate them with ease.

Locating Fuse Box in Yamaha Golf Cart

One good thing about Yamaha is that they place their fuse boxes in the exact location for each series/model of the golf cart.

For instance, the G2 electric golf cart includes fuses on the rear inner fender in the front section of the driver’s seat.

On the other hand, the 2014 Yamaha golf cart series feature a fusebox on the side of the controller, meaning you have to open up the motor to access the fuses.

In the Yamaha G29 golf cart, you can find its blue fuse block underneath the cup holder, where it’s fixed on a shelf. You must remove the featured cup holder to access the fuse block. The process is hassle-free with an Allen wrench.

Locating Fuse Box in Club Car Golf Cart

The 1986 CC DS gas-powered golf cart features a fuse box behind the dash.

In the 1997 Club Car golf cart, you can find the fuse panel near the battery box in the black electrical component.

In the 2005 Club Car precedent, you can locate the fuse box beneath the driver’s seat. It features a blue wire attachment and is fixed to the light wire connections.

The 15 amp fuse in the 2008 Club Car precedent is present underneath the controller harness on the rear.

Locating The Fuse Box in Ezgo Golf Carts

You can find the fuse box for all 2005 EZ-GO golf carts under the driver’s seat.

The 2008 EZ-GO TXT golf cart, on the other hand, features an inline fuse with a small wire connecting to the key switch.

You don’t have to worry if you can’t find your golf cart in the above examples. Use your golf cart manufacturer manual to learn about the fuse box location in your golf cart.

📋 Keep in mind: Don’t have the manual? Download or request it on your golf cart manufacturer’s website.

Step 2: Open the Panel to Look Out for The Broken Fuse(s)

After locating the fuse box, the next step is to identify the broken fuse.

  • The easiest way to achieve this is to inspect each fuse in the panel to target the one whose metal element has melted or whose glass window has discolored (turned brown or purple).
  • Alternatively, you can locate the non-functional area of your golf cart’s electrical system and then trace the fuse attached to its circuit.

Step 3: Remove the Broken Fuse

Hold the broken fuse with your thumb and index fingers, then pull to remove it.

Some golf carts house plastic pliers inside the fuse box, which you can use to remove the broken fuse.

📢 Need To Know: Ensure that you check the current rating of the broken fuse before disposal.

Step 4: Replace the Broken Fuse

Push the replacement fuse into the empty fuse slot to revert your cart to its operative state.

Ensure that the new fuse is evenly positioned in the correct depth to avoid weak connections, which may further risk the fuse blowing up.

📢 Need To Know: The fuse should have the same current rating as the broken counterpart to avoid further burnout.

Step 5: Close the Panel and Set Out for a Trial Run

You should be safe if the fuse doesn’t burn after the first 20 minutes of the test run.

While replacing the fuse may help restore the operative condition of your golf cart, it may not do away with the burnout problem until you identify the culprits behind it.

That said, you have to do the double task of replacing the fuse and repairing the defects related to electrical components/ connections simultaneously.

Assume that the 10 amp fuse has blown up due to a wiring problem in the voltage regulator. In that case, replacing the fuse may not resolve the blowup problem until you address the wiring problem in the voltage regulator.

Frequently Asked Questions About Golf Cart Fuse

How Can You Tell If A Golf Cart Fuse Is Bad?

Observing the signs can tell if a golf cart fuse is bad. However, the signs will depend on which fuse or part of the electrical fuse has gone wrong.

For instance, if the fuse connected to the starter solenoid has gone bad, the golf cart starter may not click.
On the other hand, the golf cart won’t start if the 400amp fuse connecting the main battery to the motor has blown up.

Further, the battery won’t charge if the 60amp fuse has blown out.

How Do You Check A Fuse On A Golf Cart?

Locate the service panel in your golf cart. The easiest way to achieve this is by using a golf cart manual to learn about the location of the service panel. Open the service panel to find the fuse of your interest.

Can A Blown Fuse Be Fixed?

Yes. You can remove the blown fuse from its slot and then take it to a store to get the exact replacement to fit in the empty fuse slot. However, you cannot repair the blown-out fuse to re-use it.

We advocate carrying several fuses with you to avoid the inconveniences of getting replacements in a physical store when the unexpected happens.

How Do You Fix A Blown-Out Fuse?

– Locate the fuse box in your golf cart
– Open it to locate the broken fuse (has a broken fuse and is brown or purple)
– Remove the burnt fuse and get its current rating
– Get a replacement fuse of the same quality and rating and fit it in the empty fuse slot
– Close the fuse box and set out for a test drive
