Loose Cables
Loose power cable connections are the primary culprit in the failure of traditional mechanical rotary style forward reverse switches. Power cables are the thicker, usually 6-gauge, cables that connect the forward reverse switches to the starter generator, in the case of 2-cycle gas golf carts.
OEM 6 Gauge
For most golfing applications 6-gauge cabling is adequate to the task of carrying two golfers and their two golf bags around the course, stopping every 200 yards or so while they play their next shot.
Upgrades
The larger diameter tires require more current (amps) to simply get the cart rolling. Added passengers mean more pay load demanding still more amps through the electrical system. Add a hilly or mountainous terrain and the amp draw just keeps getting higher.
Sepex Controllers
Many modern golf carts have an electronic speed controller that handles the forward and reverse switching function internally. These carts have a toggle switch of some design to change direction rather than the older mechanical rotary forward reverse switches common to many golf carts.
