Antilock Breakout Box Electrical Quick Check Sheet

This chart is used as a reference and is meant to be used in conjunction with the Rotunda(r) Breakout Box 014-00322 or equivalent, and Anti-Lock Brake Adapter T93T-50-ALA. Many of the values given for various components depend on the presence of a good ground at Pin 1.

NOTES:
- 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.

1. Keep in mind that a measurement falling outside the specification can mean one of two things:
a. The wiring between two components is worn or damaged, or
b. The component is not electrically correct.
2. Perform the following measurements with Rotunda(r) Digital/Analog Volt-Ohmmeter 105-00053 or equivalent. Check DVOM accuracy.
3. The correct overlay must be installed before making electrical checks.
