please help . i have a 2010 maxima that started losing power then all of sudden my backseat floorboard was on fire . i put it out, cut converter off and tried to start again since it didnt effect the motor. it starts but has to be jumped off with new battery in it and makes a loud rumbling sound and wont stay started for long.and can anyone send me the picture of the wiring cables to the battery terminal because someone who thought they was helping changed up the cables and it doesnt look the same as it did before. how is the fusuble link thing mounted to battery ?

 

"How is the fusible link thing mounted to battery?"

 

Battery wiring aside, i am very suprised you had no check engine lights on as it really sounds like your exhaust is blocked. Possibly the cats just off the exhaust manifold.

I know you were just wanting to know about the wiring, but cats dont get that hot without a lot of raw fuel beimg dumped. I urge you to get this to a mechanic soonest or lacking that, pull the codes and post here for further analysis!
