please check the ends is bent, broken before connecting the plug.
the ends are over long or fallen off.
The connection plug must be connected tightly.
please check if the lock up is totally fixed because connection plug is with lock up.
please check if the wires are fallen off.
do not nip the wire when installing the part.
Do not fix the wire on the over heat part
Please remove the lock up when disassemble the connection plug with lock up.
Do not bend or over move the tightwire,because the bad tightwire will cause the
