Tachometer; System Inspection - Honda Transalp XL700V Manual

Check that there is iron or other magnetic deposits
between the pulser ring and VS sensor.
Remove any deposits.
Check the sensor tip for deformation or damage
Route the sensor
(e.g., chipped pulser ring teeth).

Installation is in the reverse order of removal.
After installing the VS sensor, Measure the clear-

TACHOMETER

SYSTEM INSPECTION

• Check for loose or poor contact terminals at the
combination meter 20P (Gray) connector.
Turn the ignition switch ON, check that the tachom-
eter needle move to full scale and then returns to
zero.
If the needle does not show initial function, check
the combination meter power input line (page 20-9).
Remove the front center cowl (page 2-12).
Connect the peak voltage adaptor to the combina-
tion meter terminal and ground.
TOOL:
Imrie diagnostic tester (model 625) or
Peak voltage adaptor
with commercially available digital multimeter
(impedance 10 MΩ/DCV minimum)
Connection: Yellow/green (+) and Ground (–)
Start the engine and measure the tachometer input
peak voltage.
PEAK VOLTAGE: 10.5 V minimum
If the peak voltage is normal, replace the combina-
tion meter assembly (page 20-10).
If the measured value is below 10.5 V, replace the
ECM (page 5-77).
