03 sanger alarm troubleshooting
 

Hey guys. I have an 03 sanger v210 with the 350 mercruiser motor. I've been getting a long constant alarm lately whenever my stereo is on and I take off. Looked in my manual and it says low oil. Oil levels are perfect and pressure is always good and so is engine temp. Heard it could have to do with my voltage I do have alot of wattage it's pulling for my system. Figured I'd ask on here before I took it to the shop! Any ideas!?
