they got fried when the high voltage
from the traction batteries came in
contact with the meter's power supply.

Conversion Cost$6000 so far.
Additional FeaturesOriginal Delco stereo. In the absence of engine noise, the
interior sounds like a concert
hall while driving down the road!

Brakes are stock. Power assist comes from a Thomas vacuum
pump purchased off Ebay.

August, 2009: The bottom is now covered with Corplast. The
improvement in the car's aerodynamics is startling. Revised
consumption numbers are posted above.
Update October 10, 2009: The motor-transmission coupling
stripped out. The spline on the transmission is damaged. The
tow bill was $90.

Update April 25, 2010: I had a new coupler engineered which
has springs in it to absorb some of the shock. The car was
reassembled today and took it's first self-powered ride
since last October. The 16 deep cycle batteries are gone and
in their place are 100 BB600 nicads. The car is presently
very light, but the weight will increase again soon as I
plan to add 200 more to the back end of the car.

Update May 15, 2010: The cell count is now 200. Took the car for a two mile spin yesterday. Flawless. Hopefully some long distance testing will take place next week.

Update May 27, 2010: The car did 24.8 miles on 200 cells. No sagging at the end either!
