Sincerely, There could be something in the base, but it's hard to open. It does look like the power cord goes all the way to the top so I assumed there was nothing in line. Alternatively, can you add a starter that allows use of a plain switch? |

Glowstarters are widely available, perform poorly but work. The glowswitch is far smaller than the plastic container. A relay with brief time delay makes a much better starter. NT |

Just ordered them, thank you. Can you recommend a circuit, for 2 AA batteries? I found several with a quick search, if you have one that has a very efficient use of current I would like to see it. |
