Only check by digital meter, measured resistance each wire, compare with standard - Difficult Difficult to to judgment judgment -Up to many type of Digital meter. -Up to experience each Service man
st
1 check resistance of each wire nd if pass go to check step 2 nd
2 check by dc motor checker. Running test condition. -Easy and fast to judgment. -It can guarantee 100% to separate good dc motor before change.
