Check the battery voltage after it has not been
used for a few hours.
Voltage < or equal to 12.5 V.
Check the density of the electrolyte of each ele-
ment.
Bé = 30 ÷ 32
Specific weight: 1.25 ÷ 1.26
Make sure the negative terminals (battery nega-
tive and starter negative) are correctly connected
to each other and to the frame.

- Disconnect the fuel injection connector.
- Turn to «ON».
- Select the «PARAMETERS» function.
- Start the engine (making sure the vehicle cannot
move) long enough to measure the rpm and starter
absorption.
- Absorption at drag rpm: from 15 to 25A.
- Drag rpm: from 500 to 550 rpm
N.B.
THE VALUE OF DECLARED RPM IS THAT IN-
DICATED BY THE DIAGNOSTIC TESTER
