Control Module Power - JLG 1250AJP Troubleshooting Manual

INTRODUCTION
A.6 CONTROL MODULE POWER
Always make sure that all of the control models are properly powered. See Figure A-3. Basic Electronic Module Connections
on Pg. 6
1. For Ground Module operation, Terminals [X001.24], and [X008.2] should have a voltage of Vbatt. Terminal [X008.1]
should be grounded.
2. CAN communication wires should have 60Ω resistance between CAN HI and CAN LO whenever both the Platform
Module and Chassis Module are connected or 120Ω when one of them are disconnected. Both CAN HI and CAN LO
should be isolated (show very high resistance or overload, OL) from the shield and ground. A CAN termination 120Ω
resistor is located at both ends of the CAN bus. One is embedded in the platform module. The other terminator is jum-
pered in the chassis module.
