[ausev] question about Geo Metro conversion

[Aaron Choate]

Hi Lisa,

Welcome to the list.

Is this person using the same kit/manufacturer as you mentioned to me in
your email the other day?  I think you had mentioned that your Civic was
being done by Winderness Electric Vehicles.  I found this link that seems to
revolve around a shunt motor.
