Checking The Starter Relay; Checking The Stop Lights Relay - APRILIA Atlantic 500 Workshop Manual

Electrical system

CHECKING THE STARTER RELAY

• Disconnect the two-way connector (1) (white).
CAUTION
On reassembly, make sure that the electrical
connector (1) is correctly coupled.
• Slide the relay (2) from its hooks.
• Slide out the two rubber protections (3-4).
• Disconnect the cables from the relevant relay (2)
terminals.
• Energize (12 V) the two terminals inside the
connector (1) from the relay side.
• Use a tester (set as an ohmmeter) to check the
continuity between the two screw contacts on the
relay (2).
Correct value with relay energized: 0 Ω Ω Ω Ω Ω
Correct value with relay not energized: ∞ Ω Ω Ω Ω Ω
If the resulting values do not correspond to those
given, replace the relay (2).

CHECKING THE STOP LIGHTS RELAY

To check the working state of the relay, proceed as
follows:
• To access the relay, lift the saddle and remove the
left rear light, see (REPLACING THE REAR
LIGHT BULBS).
• Energize (12 V) the two male terminals (85-86);
• Use a tester (set as an ohmmeter) to check the
continuity between the other two terminals (87-
30).
Correct value with relay energized: 0 Ω Ω Ω Ω Ω
Correct value with relay not energized: ∞ Ω Ω Ω Ω Ω
If the resulting values do not correspond to those
given, replace the relevant relay.
