Checking The Alternator Continuity; Voltage Regulator - APRILIA Atlantic 500 Workshop Manual

Electrical system

CHECKING THE ALTERNATOR CONTINUITY

With the engine off:
• Remove the right side panel, see (REMOVING
THE SIDE PANELS).
• Disconnect the regulator wires connector (1).
• Using a portable tester, test the continuity be-
tween the yellow wires (G) of the stator.
• Also, check the isolation of the stator support.
Standard resistance: 0.1 - 1 Ω
Standard resistance between wires and stator
support: ∞ (infinity)

VOLTAGE REGULATOR

• Remove the rear part of the fairing, see (REMOV-
ING THE REAR PART OF THE FAIRING).
• Remove the right side panel, see (REMOVING
THE SIDE PANELS).
• Disconnect the connectors (1) and (2).
• Using a portable tester (scale x 1 kΩ), test (from
the regulator side) the resistance between the
wires indicated in the table below.
• If the resistance reading is incorrect, change the
regulator.

CAUTION
This inspection method is only approximate.
If possible, substitute a voltage regulator that you
know works, to check the charging circuit.
