No fissures, breaks, damage, etc. at body and terminal section?
Is the rear of the body coated with silicone grease?
Are there no abnormalities at threaded parts (stripped threads, deformation, damage, etc.) ?

Judge the result of as follows:
Judge the result of as follows:
1~ 2~ 3~
When it is difficult to measure, it is no problem also with the terminal on the same pattern.
For example. Pin 1 ---> TB-L1
Pin 2 ---> TB-L2
Pin 3 ---> TB-L3
Pin 21 ---> Relay(X52A) terminal near the pin 21
Pin 23 ---> TB-N1
