I have a Mercury 50hp 3 cylinder 2 stroke that recently caught fire under the motor cowl. It appears the wiring coming from the voltage regulator rectifier overheated and resulted in a smoldering fire. I have read where others have seen these bullet connectors or terminals getting hot and melting the plastic. Does anyone know what is causing this? I have replaced all the burnt wiring except for the two yellow wires coming from the rectifier to the wiring harness. Unfortunately, these all burned completely in two and I have no idea which yellow goes where or if there is a difference. I appreciate any help or advice!
