i have a electrical problem some where electric is not my forta' when i installed the new battery i test it at the battery and have 11 to 13 volts when installed in the jet ski sarts right up i know its charging i was at the lake rode for an hour the lopr was flashing on the display when i shut it off would not even click the starter brought it home charged battery reinstalled it within 40 min. the lopr was flashing it was dead okay where do i begin to find the problem
thank you guys

What's the voltage charging to the battery while you're riding on the water? Sounds like a regulator to me but be sure to check ALL connections.

A healthy, fully charged lead-acid battery should produce at least 12.5 volts.

When the charging system is working, the battery voltage should be about 14 volts.

Put a meter on the battery - verify 12.5 volts or more.
Start engine.
Voltage at the battery should immediately jump to 14.x volts, and stay there.

If the voltage with engine running is below 14 volts, and especially if it is below 13 volts, then there is a problem with the charging system.

Check the wire connections to the stator (Black and Yellow), check the stator charging coil with an ohm-meter, and check the connections to the LR voltage regulator (Yellow, Black, and Red/Purple).

Make sure there is no water or corrosion inside the electrical box, both front and back side of the board.

Is the battery really new, as in less than a year old since manufacture, and the first time it has been installed in anything?

First put a volt meter on the battery when it's running at 3000 RPM, should be around 14 volts.

Other than that, test the stator with an ohmeter to see if that's OK. Specs for it are in the tech section.
