Electrical Pretest

Overview

The pretest verifi es the basic electrical inputs before testing
individual circuits.

Detection

There is no detection process specifi cally for the basic electrical
supply. However, failures of this type are generally detected by the
Bendix

™

VORAD

system or the driver as some other type of fault

code or symptom.

Fallback

There is no fallback for the electrical pretest, however, it may affect
other systems.

Required Tools

•

Basic Hand Tools

•

Digital Volt/Ohm Meter
