@weron021 thank you, where did you buy the stator, what did it cost, brand? Yamaha wants close to $300 for theirs, I've found them on amazon and ebay for around $50 -$100...
There are 3 things you need to check 1. Battery 2. Rectifier 3.Stator. You may have a bad battery cell. In this case it was the Stator and we had to replace it.
