8.0 – 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.
8.1 – Start Testing
1. Make sure that the engine is switched OFF. Attach the clips onto the
battery terminal posts and the analyzer will power up and lights up the
LCD display screen as shown (Fig.29).
2. It will run through a self-test and when completed it displays the Main
Menu as shown: (Fig. 30)
