Test 1: Identify wire ends in connector. Using a digital multi-meter set to lowest scale (0-200 ohms) place
probes onto harness making sure of a good connection. Resistance should be between 47.7 and 58.3 ohms.
Refer to page 90.
If either test fails, DLA is no good and should be replaced. If both tests are good, DLA is neither shorted or open,
and should be good. Another component, connection, or input is most likely at fault.
