CHECKING ELECTRICAL INPUTS/OUTPUTS
See Figure 3-6 for the following procedure.
Troubleshoot components on main display first. Any further
testing should be completed with in-line test boards at
universal nodes. The in-line test boards can be ordered from
the Manitowoc Crane Care Lattice Team.
The node number and pin numbers for each component to
be checked is contained in node Test Volt tables.
To test a problem component at a universal node with in-line
test board:
1. Shutdown engine and turn engine key switch to run.
2. Determine universal node (3 through 5) and keyed
connector (W3, W4, or W6) where problem component
is located.
3. Remove cable to correct connector and insert the keyed
in-line test board between cable and universal node.
4. At least one cable to node computer must remain
connected when testing.
5. Determine the wire number(s) of item to be checked.
6. To test for voltage:
a. Close knife switch across test terminal on board.
b. Select voltage on meter.
c. Connect meter negative lead to problem component
ground terminal on test board.
d. Connect meter positive lead to problem component
signal terminal on test board.
e. Enable test component and check voltage reading
on meter.
NOTE: A meter reading of 9 volts can indicate an output is
turned on and is an open circuit. A meter reading of
3 volts can indicate that a circuit is turned off and is
an open circuit.
7. To test for amperes:
a. Open knife switch across test terminal.
b. Select amperes on meter.
c. Connect meter leads across test board problem
component terminal.
d. Enable test component and check ampere reading
on meter.
8. To test for a communication problem:
a. Engine must be off and engine key switch in run
position, with all brakes and locks engaged.
b. Access desired node to install communication in-
line test board.
c. Remove cable from node at W1 or W7 connector.
d. Connect communication in-line test board between
cable and universal node connector.
e. Check between terminals C (CAN high) to D
(ground) or F (CAN low) to D (ground).
f. A reading of 1 to 3 volts indicates normal
communication between nodes.
A steady reading of 0 or 2.5 volts can indicate no
communication on CAN-Bus.
