ERROR RELATED TO THE BATTERY VOLTAGE
For vehicles provided with injection, it is recom-
mended to check if there are any errors related to
the battery voltage.
The errors can be detected during the "Actual"
state but, more likely, they will be in the "Memo-
rised" state and thus with the warning lamp off.
If the error is "Battery voltage higher than the
specified value", replace the voltage regulator.
If following the static checks no anomaly is detec-
ted, it is recommended to proceed with the dy-
namic checks.
PRELIMINARY CHECK OF THE RECHARGE SYSTEM
A summary check of the recharge performance
can be performed by connecting the multimeter
with voltmeter function to the battery poles.
Observe the battery voltage during standby and
then start the engine and progressively accelerate
until 3000 rpm.
If the recharge system is efficient, the battery volt-
age increases progressively until 13.5-14.5V.
Connect an induction ammeter clamp to the posi-
tive (or negative) cables at the regulator's output.
Prepare an additional load of 140W (e.g. 4 12V
35W bulbs in parallel).
Start the engine and then connect the additional
load to the battery.
