Is this normal?? Or going to kill the battery ??

[Doctors Orders]

I have a 2005 GTX Wake... I just put in a new battery (the old one was dead) ... I noticed when putting it away after using it that it sounds like something is not shutting off after the Sea Doo is shut down and key removed. Every 10-15 seconds there is a buzzing sound and a click. It keeps on repeating.... Is this normal ?? I disconnected the neg. battery cable when I left it cause I was worried it would kill the battery. I've never noticed this sound from the engine compartment before... Is this something to be worried about ?
Thanks

Possibly the fuel pump is cycling on/off?

It kind of does sound like a pump cycling on and off- like maybe fuel pump.. why would it do that?

The power relay (30 amp) is probably stuck in the closed position, pull it out and replace it. The fuel pump is pressurizing

Feel the TOPS valve. This is the most common failure for cycling when the key is off.
