Flywheel Magneto Inspection; Rectifier Regulator Inspection; Rectifier Checkpoint Table - TOHATSU TLDI 40 Service Manual

4. Inspection
Flywheel Magneto
The flywheel magneto itself does not require inspection, however, the following precautions are
necessary when operating in the flywheel area during servicing operations. The magnets is attached to
the flywheel using adhesive glue, so it will be necessary to observe the following precautions.
Precautions
• Avoid applying shock or impact to the flywheel, such as that from the tapping of a hammer.
• Be sure to use the recommended tool rather than selecting from any standard tools that happen to be
available.
• Always replace the flywheel if it has been dropped on the floor or any other hard surface.
Resistance Values for Coils
These include values for the ignition coil, alternator coil, exciting coil, lighting coil and pickup coil.
•
Refer to the section "Specifications and Standards Used in Servicing" in Chapter 2.
Rectifier Regulator
Inspect
• For faulty connections or severed lines in the wire harness.
• Measure conductivity and resistance values by referring to the check sheet table below. (Values listed are
standard values.)
• Disconnect wiring and measure with regulator isolated from electrical system.

Note:
q
Measure using the Hioki HiTester model 3030 or equivalent product. Do not use an insulation tester.
w
The tester needle moving represents an On reading and not moving represents an Off reading. The

condition (internal power supply), testing range and the individual model.
e
Be sure to disconnect any wiring connections in order to isolate each component before measuring.
r
The readings obtained using this testing procedure are not absolute values and are intended for use
only as reference.
