BATTERY WARNING LIGHT
NOTESCheck that the status is OUT with the engine running and LIT with the engine stopped
and the ignition on.
Check consistency with the instrument panel warning light.
With the engine running, check that the battery voltage is much higher than +12 V.
Perform a fault finding procedure on the charge circuit if necessary.

Repair if necessary.
Turn off the ignition and ensure that there is insulation against +12 V and continuity in the connection:
UPC connector PEM track 8 Track 1 of the alternator 2-track connector
Repair if necessary.
With the ignition on, ensure that there is insulation against earth and the continuity in the connection:
UPC connector PEM track 8 Track 1 of the alternator 2-track connector
Repair if necessary.
AFTER REPAIRDeal with any other possible faults.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
