Terry,
Instead of a bypass fuse to keep your clock, etc maintained when you have
the battery disconnected, try a resistor. It will have to be low enough in
resistance to allow the clock (or radio presets) to maintain power, but
not low enough to run anything else. It has to have a high enough wattage
that hitting the key, or turning on the lights won't burn it out.
I'll be happy to work up the specs on the resistor soon, but not this
week.
Peace,
Pat
