Its odd, again, I fired it up, and the fuse immediatly blew (after the
variac hummmed for a second), but once the fuse was gone, the variac worked
again. The cap seems to be acting as a short to the variac.

I'm not very familiar with the variac: it was the numbers on it (1-5) for
leads, how can I tell which ones are hot, neutral, etc? I was just asuming
they were standard....

any other suggestions on to why the fuse is blowing?



I suspect some mistake in the wiring assuming there are no
defective components in the system, and assuming the
capacitor is near the correct value.  The capacitor should
not be a motor start type.    If you tell the variac
brand; General Radio, Powerstat, Ohmite, etc, and also
the model; V10, 1156, etc.,  I may be
able to give you the information for the lead connections.
But you may also may be able to do a google search for
that information and get it a lot faster.  It would also be
helpful to know the amperage, or HP of the motor, and the
capacitor value.
