This weekend I run the boat all day Saturday with no problems. Sunday morning I get up to go to breakfast fire the boat up idle out and notice the perfect pass display is blank. I hit the on off button, it beeps and locks on a speed like its suppose to but the display is still blank. I know perfect pass is very voltage sincetive so I start looking at my volt gauge and it shows while idling about 13.8 which seems high (not sure). Once I get up to about 30 mph the voltage meter drops just below 12 volts. Then after riding across the whole lake 20 min drive the belts starts squeaking just above idle. So I go back home watching the volt meter do the same thing on the way back. Any idea what could be wrong.
Just low battery from a late night ride with all the lights and radio going the night before and an old belt that isn't letting the alternater catch up.
Or is the alternater trying to lock up and getting ready to go out.
Just not sure where to go first.
