Anything on your golf cart that works harder than your solenoid would have to be the EZGO Forward and Reverse Switch for series Marathon carts. This copper contacted switch routes all of the power from the batteries back to the motor. Depending on how it is wired, it may be routing the negative side. If that is the case, the amperage is much higher. That means heat is going to build rapidly. That will heat the contacts to the point of being soft and melting on a factory switch. When this happens, the needed juice cannot make it to the motor, and you are dead in the water. This is the main reason for this heavy-duty unit.This golf cart beefed-up switch is very easy to install; all you need to do is remove the old one and install the new one the exact same way. Even though this is a heavy-duty aftermarket part, it looks just like the OEM EZGO switch. Call Buggies and place your order today.
