[DeTomaso] Fw: NPC - electric motors

[Will Kooiman]

Thanks.

I don't remember plugging in the chiller.  We didn't need to run it.  Even
if we plugged it in, it probably wouldn't have come on.  It was pretty cool
the week after the hurricane.

The pump ran for several hours, though.  If I can find the meters locally
(and not for $100+), I'll check the motor.  Otherwise, I'll just replace it
and keep the other as a spare.

Hey Will.
You might have fed the chiller from your neighbours with a long extention 
cord that might have caused a heavy voltage drop (ie: ~ 90vac instead of 
120vac). This may have damaged the motor slightly.
You need an ammeter to check the current and use a voltmeter to check the 
voltage that you have now. Compare these 2 readings to nameplate ratings on 
the chiller. If they don't match, then there is an issue.
