Where is the diode on a golf cart solenoid?
This is the small diode that mounts between the two small terminals of the solenoid on electric golf carts and utility vehicles with an electronic speed controller. Note the thin gray band on one end of the diode. The side with the band connects to the micro switch that turns the solenoid on and off (battery side).
What should the voltage be on a 48V golf cart solenoid?
This reading must be less than the above-noted battery voltage by 0.1 volts to 3 volts. If the reading is the same as the battery voltage noted earlier, the solenoid must be replaced. The solenoid wiring for an EZGO 48v golf cart is similar to that of a 36-volt cart.

What is the purpose of a diode on a solenoid?
A diode acts as a one way valve for electricity. In normal operation the electric current can't flow through the diode, so it flows through the solenoid coil.
What is a diode used for in a golf cart?
In the most general terms, a diode, whether in a golf cart charger or any other application, is a one way gate for electricity. It is direction sensitive and only allows power to flow one way through it. They are generally installed as protection against polarity reversal.

What is a solenoid on a golf cart?
A solenoid, for our purposes, is a type of relay. A relay is a type of switch that uses a low power circuit to operate a high power circuit. A solenoid uses a magnetic coil (the actual solenoid) on a low power circuit to push a rod that closes a high power circuit. On your golf cart, this high powered circuit is either your ignition on ...
Why does my golf cart have no solenoid?
Golf cart solenoids are also typically one of the first components to fail in your golf cart, because they work very hard, turning on and off every time you stop and go in your golf cart. If you have an issue with no start or no go then your solenoid should be pretty high on your list of things to check.
What is a golf cart go switch?
On your golf cart, this high powered circuit is either your ignition on a gas golf cart or your electrical motor power circuit for an electric golf cart. Basically it’s your golf cart’s go switch, and it’s absolutely essential to your golf cart’s ability to do its job. Golf cart solenoids are also typically one of the first components ...
What happens if a solenoid reads infinity?
If it reads infinity or open lead, then the solenoid has an internal fault and requires replacement. Your solenoid should also have a range that it operates in, and if the resistance reads outside of that range, you should replace the solenoid even if it works to avoid damaging other components.
What is the most important part of a golf cart?
One of the most important components of your golf cart is the solenoid. It is one of the main components of your golf cart that allows it to move. Whether you have a Yamaha, E-Z-GO, or Club Car golf cart, and no matter if it is an electric or gas golf cart, you need a properly operating solenoid to get anywhere. Contents [ show]
What to do if your solenoid doesn't work?
Before you run out and get a solenoid, you’ll have to test the entire ignition system this way to find out what’s not working, and it is a bit of a pain.
What is a micro switch on a gas pedal?
This switch is what sends the low power to the solenoid. The solenoid uses this to create a circuit between the battery and the starter, thus starting your motor and getting you grooving.
What is the solenoid on a 1997 Ezgo golf cart?
In a 1997 EZGO golf cart, the solenoid present over the speed controller has a red wire connection. The cart can be operated if there is a jumper connection from the B+ post of the connection to the solenoid post that has the red wire connection.
What is the solenoid on a 1986 Ezgo?
If you have a 1986 EZGO golf cart, the solenoid is configured as A, D, C, B. The yellow wire with red stripes is connected to the D small stud that leads to the ignitor. The cable from one large solenoid post leads to the battery while the other large post is connected to the starter/generator. The red wire from the voltage regulator is connected to one of the small solenoid posts.
How to check if a golf cart has a solenoid?
You can check if a solenoid is good or bad in your golf cart by following the steps given below. Raise the rear tires of the golf cart from the ground. Keep jack stands below the axles so that the golf cart doesn’t start moving accidentally. Remove the charger from the golf cart and set the Run/Tow switch to Run mode.
How to wire a cart?
You can do this by following these steps. Connect the main positive battery terminal to one of the two large solenoid terminals. Connect the positive terminal of the cart’s controller to the other large solenoid terminal.
What is the white band on a golf cart?
The white band must be on the positive side of the small solenoid terminals. If you’re using the original controller of your golf cart, it’s worth noting that it comes with the setting for a 36-volt solenoid. You’ll have to get it reconfigured for a 46-volt solenoid.
Where do you connect a voltage reducer to a control switch?
If you plan on using a voltage reducer with a control switch wire, then the reducer must be directly connected to the solenoid bolt that is opposite of where the positive output of the battery pack is connected to the solenoid.
What are the settings on the M3?
The variable settings on the M3 allow a player to adjust the loft, lie, and face angles of the club, as well as create a variable fade or draw bias. Which can correct many swing or hit issues...

What is diode in electric vehicle?
Details. A diode is a protection device across the contactor coil (solenoid relay) and in general, is a one way gate for electricity. The contactor coil is an electromagnetic device in your electric vehicle which controls the flow of power to your electronic speed controller.
How to test a diode?
To test the diode, disconnect one end from the solenoid and connect a ohm meter to each end of the diode. There should be a partial ohm reading in one direction and no reading in the other direction. Any other results indicate a bad diode. Please click on the picture to see the diode mounted on a solenoid used for electronic speed controlled carts.

How does a contactor create a magnetic field?
When the contactor is energized, a magnetic field is created that pulls or pushes a movable bar or plate to make a connections between a fixed set of contacts. To create the magnetic field, a current is passed through a coil of wire. The magnetic field remains as long as there is current present.
What happens when a contactor is turned off?
The magnetic field remains as long as there is current present. When the contactor is turned off, the current stops, an the magnetic field collapses causing a "voltage spike" or " fly-back voltage" that can damage the controller. This voltage can exceed 150V.
Which side of the diode always faces the battery bank?
The diode always goes across your smaller contactor terminals and the striped side always faces the terminal coming form the battery bank. The other post usually leads on to the controller. The type and size of diode is dictated by the size of the contactor.
Why do you need a quenching diode?
Quenching Diodes: Anytime that a relay coil is driven by a circuit that is not specifically designed to drive a relay, you should use a quenching/suppression diode connected in parallel with the relay coil. Initially, you may think the diode serves no purpose because the voltage applied to the relay cannot pass through the diode.
What happens when power is removed from a relay coil?
When power is removed, the magnetic field collapses causing a reverse voltage to be generated (it's called inductive kickback or back EMF).
