- Connect the break-out box 981 3190 Replaced by 9511428 981 3190 Replaced by 951 1428 using adapter 981 3194 Replaced by 9511495 981 3194 Replaced by 951 1495 on the 16-pin green connector (terminals 31-46).
Connect an ohmmeter between battery negative terminal and:
- terminal 36 on break-out box
- terminal 37 on break-out box









In both cases the ohmmeter should read 0 ohms.

OK - Calibrating ground terminals, continued

Not OK - Checking for an open-circuit
