The EZGO and Yamaha Thirty-Six-Volt Four-Terminal Solenoid is the shot caller of your carriage. This unit sends all of the power to the controller to make the caddie run. If it decides to take a day off, you are not going anywhere. Unlike you, when a golf cart solenoid calls in, it's usually for good. It is very seldom that relays like this give up the ghost intermittently. Once they click off that first time, having it come back is a rare occurrence. If your problem comes and goes, it could be something different, like a micro switch.Speaking of golf cart micro switches, a full activation circuit gets your golf cart solenoid to make that familiar clicking noise. Several relays, including the key, contribute to the positive and negative signal the solenoid needs to activate. If even one of them starts to fail, it can make it seem like the main contactor is to blame when it could actually be something much cheaper. The last thing you want to do is jump the gun and find out that you could have saved a bunch of money. We want you to get it running the first time around.Getting your thirty-six-volt four-terminal solenoid from Buggies Unlimited installed is a simple thing to do.
