In the morning when I cold start my 78 FJ40 (original stock) it takes multiple turns of the key before the engine will start. Periodically I will see a little smoke coming from the the engine compartment so I went to investigate. I noticed that the smoke was coming from the connection of the positive battery cable to the starter....the wire covering was melting due to the multiple engine turn overs before it starts. Why would the wire be melting and smoking. I did replace the wire awhile back. Perhaps I need a different wire that would better handle to voltage push from the battery. Or is there another issue I should look at....am I at risk of fire. When the motor is warm and the temperature is warmer I do not notice this issue. Perhaps tuning in carburetor would help in starting then not putting the stress on the positive battery cable....Thoughts
