â€¦.if youâ€™re used to using the safety stop switch (kill switch) up on the handlebars to stop your sled, youâ€™ll want to change your ways if youâ€™re riding a new sled with electric start. This is particularly true on Yamaha models, where if you leave the key on and the kill switch â€œUPâ€ the battery will discharge. Even if left for a period that doesnâ€™t totally drain the battery, this practice will cause premature failure of the battery since current draw occurs when both of these switches are left in the â€œONâ€ position.
On Yamaha models, you wonâ€™t hear anything if the key is on and the kill switch is pulled up, but the electrical system will be ON. On the Arctic Cat models youâ€™ll hear the fuel pump pressurizing the fuel rail for a moment and the dash lights will come on, so youâ€™ve got to be totally ignorant to not realize youâ€™re draining the battery. The Yamaha dash lights donâ€™t come on until the engine fires, making them more prone to accidental discharge.
For these reasons, the key should always be in the â€œOFFâ€ position when the sled is off. This requires a change in what has become a way of practice for many of use, using the kill switch as your on/off switch.
