Recharging regulator

Hi, I have a problem with the recharge controller. When running the engine, I found that the connector and wires from the alternator get extremely hot. So is the charge controller. It sends almost 15V to the battery. Do you know what the problem is? If the regulator is faulty? Thank you for the series.

It’s a well documented problem with the connectors overheating,either strip and clean or replace them.
The regulator does get hot during normal operation,it dissipates excess electrical energy as heat but if it is pushing 15v to the battery I would be looking to replace it
