CHECKING THE FUEL INJECTION RELAY

To check the working state of the relay switch, pro-
ceed as follows:
• Remove the rider's saddle, see (REMOVING THE
RIDER'S SADDLE).
• Energize (12V) the two male terminals (85-86).
• Use a tester (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 values do not correspond to those given above,
replace the relevant relay switch.
CAUTION
For main fuel injection relay only:
Respect polarity, energizing the terminal (86) with
"+" and the terminal (85) with "-"; a diode is
present on the inside.
