If there is a more important part that should be covered, it would be the cells of your batteries, but this is a close second. The Club Car DS V-Glide Switch Case Cover protects the copper contacted throttle sensor. This unit is responsible for sending the signal to the controller that indicates how far you have pushed the throttle pedal. That's on the solid-state caddies only. If you have a vintage resistor coil system, it sends all the power down heavy cables to a large bank of coils. Either way, it's a very crucial player for your golf cart's ability to run. Keeping it free of dust and corrosion helps elongate the amount of time it's usable. Getting the most bang for your buck is what we are all about.This golf cart switch case cover is a great way to keep things clean. If yours is cracked, it's only a matter of time before it's broken and then missing. Act now and call Buggies Unlimited for a replacement cover before contacting us for a replacement throttle.
