Hi Eric,

This is only a guess, but as an old electronics tech, I have seen things
like this quite often. I suspect that when you turn the washroom fan off,
the collapsing magnetic field in the fan motor is generating a voltage spike
on that circuit. The spike may be affecting your input power on your Pismo.
I would strongly suggest you keep your Pismo off that circuit, voltage
spikes strong enough to get by your adaptor's voltage regulator and filters
have a potential to cause problems.
