GTX 4tec supercharged limited - 12v indicator

[Jetskichick]

2004 GTX 4Tec supercharged limited and the 12v battery indicator comes on the display.
Changed the battery and the regulator
It was fine for a month and then display is reading 12v low again. Also had a low oil pressure light. Any ideas?

Did you load test the battery,,,did you check that it is charging?,,,check the 3pm statir connector at the rear above the stator case,,,they tend to overheat over time,,,causing resistance,,,reducing the output to the regulator to regulate.
