Continue - Checking ground terminals

-------------------------------------------------

Checking ground terminals








- Ignition off.
- Switch off all equipment that takes power from the battery (courtesy lighting, radio etc).
Connect an ohmmeter between the battery negative terminal and
#15 (#A15)
#17 (#A17) on the breakout box.









The ohmmeter should read approximately 0 ohms for all readings

OK - Return to the fault-tracing procedure where it was interrupted.
No Fault Found

Not OK - Checking for an open-circuit

-------------------------------------------------

Checking for an open-circuit
Check ground terminals 31/50 and 31/51 in the central electrical unit and their cables for an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault and contact resistance and oxidation according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
