Actually, it will handle the load of up to 3 gauges.  But since it's
operation is independant of load, it will continue to work correctly with
only one gauge (or none).

Might be a good time to point out that it doesn't really "stabilize" the
voltage ... it's output swings between 0 volts and full battery voltage such
that the _average_ is 10 volts.  It actually works rather like a "heavy
duty" turn signal flasher, with a resistance heater and a bimetal strip that
runs a pair of contacts.  If you hook a test lamp or meter up to it, you can
see it "flash".

Or, you could always pick up one of the solid-state replacements on eBay,
which do hold a constant 10.0 volts output (and probably will handle more
gauges to boot).
