2001 cr80 No Spark

[mgautreau]

I'm trying to diagnose a CR80 with no spark. So far I've:

1. Unplugged the kill switch.
2. Tried a new plug.
3. Put an ohm meter across the trigger and observed it make/break as I crank.
4. Put a volt meter across the stator and observed 10-12vac from the stator.
5. Used a 12v battery directly to the coil and made the plug fire.
6. Installed a used module from ebay (supposedly good).

So now I'm wondering if I've got a bad module or the stator output is too low. Does anyone know what the stator output should be or is there another way to check it? Any other suggestions?

Thanks in advance for your help.

You need to check the stator on AC voltage. You should have about 120-160 volts coming out of it.

Get a shop manual or ask your local honda dealer if they can look up the specs on that stator output for you.

There are resistance (ohms) specs. for the generator coil(s), the trigger coil, and the main ignition coil. Check all of these first. These specs. will be in a good service manual (ex. clymer, or haynes). If all of these check out good, be sure that there are no shorts in the wireing harness. Check the coil grounds for good contact. It is possible that the CDI maybe bad, but there is no way to test it. It can be assumed that if all other components check out good, then the fault is the CDI modual.
