Antilock Breakout Box Electrical Quick Check Sheet

This sheet is used as a reference and is meant to be used in conjunction with the Rotunda EEC IV Breakout Box 007-000033 or equivalent, and jumper connector.

Many of the values given for various components depend on the presence of a good ground at pin 1.


The pin 1 chassis ground must be verified as sound before any quick electrical check involving pin 1 may be used. At any time, any known good chassis ground may be substituted for a pin 1 designation.

Connections between components must be verified as sound before replacement of affected components. Failure to observe above will often lead to improper replacement of components and incorrect resolution of concern. Replacement of good components will not resolve a vehicle wiring concern.

Keep in mind that a measurement falling outside the specification can mean one of two things:
1. The wiring between two components is worn or damaged, or
2. The component is not electrically correct.

Quick Check:

NOTES:
- Perform the measurements on the above chart with Rotunda 105-00053 Digital/Analog Volt Ohmmeter or equivalent.
- Overlay 007-00103 must be installed.
- Check for continuity between pin 1 and chassis ground or invalid results may be obtained. Results not matching specification indicate either a wiring or component concern. further analysis is needed before any component is replaced.
