8.4 Rough CCA Guide
Given below is a rough CCA ratings guide for any unknown battery model basing
on the capacity of the vehicle:
Vehicle Capacity Approximate Battery CCA Rating
1200 ~ 1600 cc 350 CCA
1600 ~ 2000 cc 500 CCA
2000 ~ 3000 cc 650 CCA
3000 cc and above 750 CCA
M. Benz over 3000 cc 760 CCA
9.0 – 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 be subjected 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 Analyzer will measure the resistance from
the engine body contact to the battery terminal then it will display the results and
the recommendations.
9.1 – 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.35).
