Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
You said the coil was melted? Is that correct? Where did you buy the Crank Sensor you installed? Did you change the Cam Sensors as well?
When the coils burn up, that is due to a broken ground cable. Where the negative battery cable comes off the battery, it then goes to the frame to a 10 mm bolt, then to the transmission to a 14 mm bolt. It breaks or almost breaks at the transmission. When this happens it builds up to much heat in the ground circuit and the first circuit that is affected by this is the ignition circuit ( meaning the coils ).
Now the not so good news.
To resolve this, the negative battery cable needs to be replaced and all 6 coils. Failure to replace all 6 coils will result in this issue to continue to happen..
