Test 11—Testing for Voltage at the Fuse Box
Use a digital multimeter for testing voltage at the fuse
block (1).
To test for volts DC at any given fuse socket, place the
positive lead on any metal fuse contact (2) and the negative
lead on the grounded fuse box chassis (6). Repeat this
procedure using the other fuse contact as a test point. All
fuse sockets except F16 (3A, 10V) should be 12 volts DC.
To determine if the K1 cab power relay (7) is fully functional,
ground the fuse box chassis and check for 12 volts DC at
relay wire 8 when the relay is enabled. Also check for 12
volts constant at relay wire 5A.
