ELECTRIC SYSTEM - DIAGNOSIS AND TROUBLESHOOTING
● GROUND TEST
The ground connection is critical for the electric and
electronic circuits' operation. It is often exposed to sev-
eral factors for corrosion such as humidity and dust.
Corrosion produces unnecessary resistance and this re-
sistance can affect the circuit operation. Also, electrically
controlled circuit is very sensitive to ground.
If the ground wiring is loose or corroded, it can greatly af-
fect the electrically controlled circuit.
Even though the ground connection seems to be clean,
there might be a thin corroded layer on the surface.
Perform the following steps for inspecting the ground
connection.
Remove any ground bolt and clip.
Check if there is dirt or corroded layer on the surface.
Clean the surface completely for proper connection.
Tighten bolts and screws fi rmly.
Check parts related to the ground circuit.
If several wirings are connected to one ground termi-
nal, check for proper connection.
All wirings should be clean, securely tightened and
properly grounded. Even the wirings connected to the
one ground point should be cleaned before they are
reinstalled.
