2001 Waverunner constant battery drain
I have a 2001 Yamaha Wave Runner that has a battery drain problem even when the jet ski is off. If the battery is charged fully and left to sit for a day, the battery doesn't have enough left to start the jet ski the next day. It has a brand new battery that was installed to try to fix this problem but it didn't help. Something is draining the battery when it is off and the key is removed.
Ideas on what to check?
