A diode is actually a "one way valve" for energy, so Each individual diode should really present some resistance reading through to the meter one way, and no studying, or infinite resistance the opposite way. A bad diode will either have infinite resistance both of those approaches, or will conduct some current (show a looking at about the meter) both of those ways.
Labour instances and portion selling prices range depending on the certain automobile, but to give you an concept here are some illustrations.
