Low Battery light and beep malfunction

[bigflyhitter]

on my 2005 islandia the low battery warning light and beep goes off everytime I leave my radio on for just a few minutes after I turn off the motor. I know the battery is good because it did this after I put a new battery in. Any one have any insight into this problem?

Just because the battery is new, doesn't mean it's good. If the voltage is sagging, then the beeper will sound.

Put a volt meter on the battery, and turn the radio, and see if if stays above 12v.

Maybe a loose battery connector. I have had that before. It can mess with the ground and cause some strange issues.

I would say you are right but it only happens with the radio. I can run lights, run my air pump for 30 mins blowing up tubes and nothing, but 2 mins after I turn on my radio the light and beep start sounding.

My boat and everything ran fine but I had that annoying buzzer going off and that is what it was.
