Details:

This was purchased along with all the parts to convert a Ford Escort into electric vehicle. I have the throttle pot box also / condition unknown that will include. I do have the receipts from purchase in 2004. The DC motor is gone.

This Curtis controller 1221C-7401 72-120 VDC / 400AMP with manual was bought in the year of 2004 by a friend mine. Very few miles maybe a hundred at most put on the car. The car was built tested and certified full electric in 2005 then taken apart never to be put back together. This controller has been sitting in the house since then.
