question is

is the wire always hot ???
my battery is more than two year old, car did not start i start the car from another car

is the battery need to replace???

please advise

 

A wire should never be hot.

Aside from a short, you might have a loose connection or a break in the wire.

If moving the wire helps, then look at both ends of the wire and make sure that the connecting surfaces are clean and that the connection is tight.

If you disconnect the battery, wait one hour, reconnect the battery, wait 15 minutes and check the wire again without doing anything else, and it is again hot, then you have excessive current draw beyond the wire.

It is not a battery problem, it is a wiring problem.

 

thanks for the prompt reply

the wire is only hot when the car engine is running otherwise its normal

 

It should never be hot. You will need to determine the reason why.
