For those who have unfortunately read the Clymer manual you will note it purposely omits the CDI test saying it was unreliable and that Honda even disowned the test. This is partially true, but the main reason the test was unreliable is that people were using analog meters back then and those meters were very sensitive to the battery voltage remaining so you'd get a fair amount of false readings.
The following tests assume you have a fresh battery. CDI and meter should be about room temperature or the readings may change a little bit. You will likely have variations in numbers. About 10-20% variation should be OK. If in doubt, ask.
Here is the official FSM test with an Analog Meter. Make sure the scale is zeroed. You will want to use Kohms setting on your meter. Polarity of the probes matter.
Here is my test for use with a Digital Meter. You may have to set the "range" manually or you will get strange results. Polarity of the probes matter.
