Every golf cart has a relay. We don't care if it's gas or electric; each of the units has one. It's like hair color; everyone has it, well, except your dad. He's got a little up there still! That cul-de-sac cut is maintained as neatly as his yard. But just like his queue ball is a little different than everyone else's, so is the Yamaha Solenoid for Gas G1 caddies. Most contractors have four terminals; this one has six. Because this is a two-cycle coach, the voltage must get delivered to more places. You cannot use a basic car solenoid in place. It will not transmit the voltage properly, and it only pulses duty. A golf cart switch is continuous.This golf cart solenoid is identical to the one that was on your buggy. This makes things very easy to install. It is not a Yamaha product as they no longer make it, but it is identical to the OEM relay. Give Buggies Unlimited a call today.
