Around August/September of 2023, there was a batch of B213 chargers manufactured with fuse caps where the spring was sitting too low, thus causing the fuse to malfunction.
If the cart has a serial number with a ship date between August 2o23-Jan 2024, have the user check the fuse to see how it is sitting in the cap compared to the image above. Also, if the charger LED lights only stay at RED+GREEN not RED+YELLOW when the cart is being charged.
