Hi, I have a 400W motor controller that is in a metal box and it is=20
potted.  I'm curious if there are techniques to remove the potting.  The=20
box is approx 2"x2.5"x1".  The 2"x2.5" dimension is open and the potting=20
is (up to) 1" deep.
Background: This is for a 24V 400W DC brushed motor on a ThinkMobility=20
Funbike.  I've found little documentation on the bike.  The controller=20
has input lines from pedelec and speed sensor, as well as a cable from=20
the handlebar mounted "brain".  Wiring everything to the battery results=20
in no lights on brain and no power to the motor.  I'm looking at generic=20
controllers on eBay ranging from $32 to $60.  I don't currently have the=20
tech shop or junkbox to just wire something up.
