SCARABEO 500
1) Remove the central cover.
2) Disconnect the connector between the stator and the regulator located near the fuel pump.
3) Measure the resistance between each yellow terminal and the other two.
Electric characteristic
Resistance:
0.2 ÷ 1
4) Check that there is insulation between each yel-
low cable and the ground lead.
5) If incorrect values are detected, replace the sta-
tor.
Recharge system voltage check
Maximum generated current check
•
With the engine off and the panel set to «ON» turn on the vehicle lights and let the battery
voltage reach up to 12V.
•
Connect an ammeter clamp to the 2 charging positives in the regulator output.
•
Keep lights on, start the engine, take it to a high running speed and, at the same time, read
the values on the ammeter.
With an efficient battery the following value must be detected: > 20A

WARNING
BEFORE CHECKING, MAKE SURE THAT THE BATTERY IS IN GOOD WORKING ORDER.
1) Rest the vehicle on its centre stand.
2) With the battery properly connected to the circuit, place the multimeter probes between the battery
poles.
3) Start the engine, making sure that lights are off, increase the engine revs and, at the same time,
measure the voltage.
