Wiring Reference Data
NOTE:
When troubleshooting the electrical wir-
ing harness for your lift truck, the wire connectors
may be different but the pin numbers for the con-
nectors are the same between the different con-
nectors.
Function/Circuit Identification
— A standard num-
bering and color-coding system is used in the lift truck
wiring. This system will simplify repairs. The Electrical
Circuit Identification Specification is ES-1359. The ID
data is described in Table 9030-03-1.
Each circuit Function ID has a number from 1 through
999, as indicated in the Table 9030-03-1.
•
A circuit labeled with a single numerical Func-
tion ID shall be electrically equivalent through-
out the harness (physically connected through
splices or connectors).
•
Wires which are connected only through an in-
ternal connection in a controller shall have sep-
arate Function ID numbers.
•
Wire Function ID numbers will be stamped at
50mm intervals along the wire length.
•
The Function IDs are assigned into groups as
shown in the table. Unless noted otherwise,
specific functions are to be preassigned to
unique Function IDs.
If a circuit function does not meet one of the preas-
signed numbers, and its function is unique within the
truck series and option, then a number from the “Non-
Standard Functions” range may be used.
