Jim, I forgot to add in my previous note what Jerry reminded me about:
Be absolutely sure that you connect the Astron to the battery through an
adequate fuse. If the Astron should fault and crowbar, you will not be
able to find enough smoke to replace what will leak out! The battery will
in all likelihood simply explode and start a fire. Bad Karma . . .
