Basic Electrical Diagram of Electronic Governor System
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 51.
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.
Test 2: 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 51.
Proceed to DLA Circuit Test.
Turn key switch to ON position. Test supply voltage to GCU using volt meter. Refer to page 50 (battery
voltage +/- 1 volt) Note: Prevent Damage to Connector. Do Not Use Oversized Probe Tips.
