Does anybody know the resistance and ohmage of these things?
Resistance and "ohmage" are the same thing. The current rating
(amperage)
would be nice to know, however. The resistors should be rated to handle
at least the same current as the fan motor fuse (not sure what that is
offhand).
Seems you could replace them with several 3-terminal regulators of
selected
voltages which wouldnt get hot, waste amps or burn out
3-terminal regulators will put out as much heat as an equivalent
resistor,
and they'll waste just as much power. Their advantage would be that
they'd
supply a more constant voltage, which isn't so critical for this
application.
A switching regulator would be efficient and cool, but expensive and
complex
overkill.
But I'm with you, these resistors are obviously underrated, because
they
so often fail. A beefier power resistor, rated to handle more current,
would be a useful upgrade.
