2006 30' MS W/ 315hp Yanmar motor.
While working on removing my raw water pump I noticed a slight melting on the plastic wire covering the terminals to the battery isaloater. I have a picture of the unit attached. I did not upload the pictures of the wire ends. My question is where to start looking for the cause of the problem. I have sent an email to Marinco asking the same question.
have this issue? Everything works fine on the boat.
