age regulator (with connector disconnected); the
measurement must be ~8 M/Ohm. If the value
measured is far from that indicated, replace the
regulator because it is in short circuit.
b) Battery fails to recharge (regulator interrupted).
To check if there is any failure in the voltage reg-
ulator recharge section, first connect 2 testers to
the battery (one to detect voltage and the other to
detect current) as indicated in the second figure
and follow the procedure below:
Start the engine (temporarily connect the red cable
to the battery positive terminal in order to avoid
damaging the device that measures current).
Check there is at least 13V (charged battery) and
a recharge current of 1.5 ÷ 2A with the vehicle
lights off.
As the engine rpm increases, so do the current and
the recharge voltage; with rpm over 4000 there
must be a recharge current of about 4.5A; when
the vehicle lights and the stop light are switched
on and the horn is powered, current values below
or equal to 5A and a voltage value of 14 ÷ 14.5V
( regulator threshold voltage) can be registered. If
values other than those above are detected, re-
place the regulator; contrariwise, check the cable
harness and the connections.
Starter motor
Test to be carried out to check the electrical starter motor
1) Check the battery charging conditions.
2) - Check the remote control and the system. The check can be carried out by replacing a 12V-35W
bulb of the starter.
- If the bulb turns on, replace the starter motor.
- If the bulb does not turn on, check the system and the remote control.
