1982-on Honda Cub/Passport with CDI Ignition: Tests in the Honda Manual - a How To by Jon Pardue Sarasota, Florida USA Here's the page from the factory Honda manual that explains how to test the CDI components. It instructs the reader to use either a Sanwa or Kowa electrical tester, which virtually no one has. The various tests are described in "truth tables". These can be hard to interpret. This How-To illustrates making each test using a commonly available electrical multitester. if its this good its from the labs and workshop of jon pardue 1982-on Honda Cub/Passport with CDI Ignition: The Tester by Jon Pardue Sarasota, Florida USA The multimeter illustrated is available at Harbor Freight. Radio Shack, Wal Mart and auto parts stores also have inexpensive multimeters. 002 OHMS Here we are setting up the meter according to the tests Honda expects us to run. The meter's internal battery sends power through the probes and measures the resistance of the probes, wires, and the circuit being tested. This basic test verifies the meter is working properly. This simple test shows the meter probes and wires have 2 Ohms of resistance. Your meter may read Zero Ohms or a few Ohms. These low cost meters may display varying readings during this test.

A solid wire measures close to Zero Ohms. Insulation is an open circuit. An open circuit = INFINITY on a meter Meter set to check resistance. The maximum resistance reading possible at this setting is 2,000 Ohms. Honda's tests for the CDI and Ignition Coil range from almost Zero Ohms to 800 Ohms. if its this good its from the labs and workshop of jon pardue 1982-on Honda Cub/Passport with CDI Ignition: the Tests by Jon Pardue Sarasota, Florida USA The yellow box explains what the CDI unit is connected to on your bike.
