wires to stator and rectifier warm to hot

[hagedorn45]

Wires to stator got hot and fried the plastic connectors suggestions had me replace the rectifier and cut out the plastic connectiers and splice wires to stator the wires are still getting warm to hot but can hold on to them and not burn my fingers. Is that normal for wires to rectifier and stator get hot but does not melt the wires. I believe the wires to the stator fried because I used a car to jump the battery and unfortunatley started the car and was told that might have done in the wires.
