7.4 Grounding Test
The engine body and the vehicle chassis are always connected to the battery
negative terminal to provide the electrical return path (grounding) for all the
electrical components. Due to the surrounding environmental effect, the surface
contacts of these joints or connections of these circuits will subject to oxidation
and corrosion in a matter of time rendering them to have high resistance in it.
One typical example is the connection at the battery terminals where oxidation
and corrosion takes place very often. If these contacts were no good then it will
pose a lot of electrical problems to the vehicle.
To check the grounding condition, this Analyser will measure the resistance from
the engine body contact to the battery terminal then it will display the results and
the recommendations.
Start Testing
1. With engine OFF, place
PARK for Automatic and apply the parking brake.
2. Attach the Analyser clips onto the battery terminal posts and it will power up
and lights up the LCD display screen as shown (Fig.64). Press
the display will show as Fig. 65 below.
