BMS over temperature circuit tripping

Our 100A fuse has been tripping recently and we believe it only occurs when the alternator is charging. The BMS is showing the over temperature LED. I have disabled the alternator for the time being but what could be causing this trip/over temperature? The writing diagram shows it is a 160A breaker but it is 100A.


The BMV showed a peak current of 60A coming from alternator.

Hello,
I dont see the over-temperature LED on in your pictures. The orange and yellow one are on.

Do you have another picture with the LED on maybe or is the orange one you are talking about?
