RECHARGING SYSTEM
•
Disconnect the six-way connector (1)
(black colour) located behind the left
side cover.
NOTE
THE ENGINE SIDE IS IDENTIFIED WITH THE LETTER "A"
Measurement of resistance (with engine off)
•
For a correct detection of the alternator
resistance, an ambient temperature
measurement must be carried out and
afterwards a heat stabilisation (after
turning fan on) by using a tester, using
alternatively 3 of the 5 connector pins
(no. 2, 4, 6): stage "1" (pin 2-4), stage
"2" (pin 2-6), stage "3" (pin 4-6).
•
Take the measurement; The correct value is determined by the value measured for each
stage in which from time to time the resistance of the tester wires is subtracted, obtained by
touching the two lugs.
Example:
•
Resistance of stage 1 read on the display = 0.67 Ohm
