A spark, well that is easy.  I have a new 1000 W Zantrex inverter and every
time I replace a blown fuse for it (30Amp I know it should be more but
that's what I use and it works) it sparks a little bit.  I figured that was
normal.  And no, I don't leave the switch in the on position on the
inverter.  But odd that a good quality inverter would be causing a problem.
Maybe something is touching something it shouldn't.

Thanks,
Dave
