Bob, Jeremy is talking about the ign. modules shipped with the earliest generation 20's. It drove many nuts. Could go into detail regarding them, but there's not many around still making owners crazy.

You can tell if you have one easily by looking at the max input voltage for the module. If it's 8.4v, you have the newer one that does not have the issue Jeremy describes.

If you have an older one, be happy to go into it. -Al
