Check System Voltage Measurements and Grounding Best Practices
2-4 MAY CONTAIN U.S. AND INTERNATIONAL EXPORT CONTROLLED INFORMATION 80-JB423-1 Rev. F
Check System Voltage Measurements and Grounding
Use the same ground reference that a particular circuit uses.
• Check the MAS110 light indicators.
• Verify that vehicle battery and cables are in good condition.
• Check voltages (see Appendix A for more information):
- Power cable: you must use pin 8, 14, or 15 as the ground reference.
- Display cable: you must use pin 1 or 8 as the ground reference.
• Verify grounds:
- Run a jumper lead between the power cable ground connection and the battery
negative (-) terminal.
- Make sure the fastener is tight and the metal is free of paint or corrosion.
- Make sure the grounding point is well-connected to the vehicle chassis ground or to the
negative terminal of the battery.
Replace Only Faulty Parts
Typically, only one part is bad. Once the system is operating, you can substitute suspect
parts back into the system to verify which part is bad, or use a test cart equipped with known
good spare parts to retest suspect parts.
Install Parts Correctly
Refer to the MCP110 Installation Guide.
Determine If the Problem Is Intermittent
Check for:
• Bad or loose electrical connections including cable connectors, ring terminals, butt splices,
