Solenoids and Contactors
36V and 48V golf cart solenoids and heavy-duty contactors from White Rodgers and Albright, matched by voltage, terminal count and OEM part number.
pick your voltage, then the type and your cart.
Choosing the right golf cart solenoid
The main solenoid is the heavy switch between your battery pack and the controller. Three things decide which one you need: the voltage that feeds its coil, the number of terminals, and how hard the cart works.
- Voltage. A 36V cart needs a 36V coil and a 48V cart a 48V coil. The coil is voltage specific, so a 36V solenoid on 48V overheats.
- Terminals. Most carts use a 4-terminal solenoid: two large studs for pack current and two small posts for the coil. Some older 36V carts use a 6-terminal SPDT unit with studs on both ends.
- Duty. A stock-style 200A White Rodgers 586 bolts in where the original was. The Albright SW180B heavy-duty contactor suits upgraded controllers and hard use. Navitas recommends a 200A or bigger solenoid when a cart works harder.
Every product page lists the OEM numbers it replaces, the full manufacturer ratings and the data sheet. Not sure? Send us a photo of your old solenoid and we will match it.
Solenoids and Contactors FAQ
How do I know if my golf cart solenoid is bad?
Press the pedal and meter across the two large studs. Near 0V means the contacts are closing properly. Several volts means burnt contacts, and full pack voltage with a click means they are not closing at all. Our solenoid test guide walks through it.
Can I use a 36V solenoid on a 48V golf cart?
No. The coil is wound for 36V and overheats on 48V. Match the coil voltage to the voltage that feeds it, normally your pack voltage.
Do I need a heavy-duty solenoid with an upgraded controller?
Usually yes. Navitas recommends a 200A or bigger solenoid when the cart works harder. A 200A White Rodgers 586 covers most builds; the Albright SW180B adds headroom at high duty.
Does a new solenoid come with the resistor and diode?
No. Move the pre-charge resistor and coil diode over from your old solenoid if your controller uses them. Navitas controllers do not, and their manual says to remove both.
