Default Lights dim with swamp cooler.

Thanks Guys,

The power drop sometimes scrambled the tiny-brain of an Arduino
temp-sensor I have running from the same outlet. It still does the
same to the Temp sensor if I plug it into another outlet. I have some
10K-electro-caps coming for the Arduino 5vdc line, so that should stop
that.

Other than that, the dimming is annoying to some members of the
household.

==================

Do you have large resistive loads like space heaters, toasters or
coffee pots that you could use to trace the steady-state drop? The
problem might be the cable connections in the panel or the meter box.

I had a problem with a poor connection to neutral, which caused the
two 'phases' to unbalance when a motor started. Some lights dimmed,
others flashed brighter. The power company cured it by replacing the
meter box and weatherhead cable. They knew the old aluminum splices
tended to corrode.
