CHECKING ELECTRICAL INPUTS/OUTPUTS
See Figure 3-4 for the following procedure.
Troubleshoot components on main display, system
diagnostic screen first. Any further testing could be
performed with in-line test boards at universal nodes or
Manitowoc Unit Tester at all nodes. The in-line test boards or
Manitowoc Unit Tester can be ordered from your Manitowoc
dealer.
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 the engine and turn engine key switch to
stop.
2. Determine universal node 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 a voltage:
• Close knife switch across test terminal on board.
• Select voltage on meter.
• Connect meter negative lead to problem component
ground terminal on test board.
• Connect meter positive lead to problem component
signal terminal on test board.
• 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:
• Open knife switch across test terminal.
• Select amperes on meter.
• Connect meter leads across test board problem
component terminal.
• Enable test component and check ampere reading
on meter.
Test for a communication problem on a universal node with
communication in-line test board:
1. Engine must be off and engine key switch in run
position, with all brakes and locks engaged.
2. Access desired node to install communication in-line
test board.
3. Remove cable from node at W1 or W7 connector.
4. Connect the communication in-line test board between
cable and universal node connector.
5. Check between terminals C (CAN high) to D (ground) or
F (CAN low) to D (ground).
6. A reading of 1 to 3 volts indicates normal communication
between nodes.
7. A reading of a steady 0 or 2.5 volts can indicate no
communication on CAN-Bus.
