would a guy buy a perfectly clean classic truck, then gut out the gas
motor, fuel tank, radiator, exhaust
and all that cool polluting stuff and throw it in a big pile for the scrap yard? Beats the hell out of me.
Must be one of those eccentric green tree-huggers you hear about who can't stand dirty air or high gas prices.
Or maybe there's more...
about innovation, using your skills to make something better? A
performance boost, no more tune-ups,
and the thrill of thumbing your nose at the gas stations when you stop in only for coffee and cigars?
Well it works for me. Could have bought a new car for the cost of the conversion, need to recharge every couple hundred miles
(see the solar barn link), and called in a few favors from the local experts on metals and machining.
Was it worth it? Hell, YES !

about a ride to wherever you want to go without depending on oil
companies, even the power grid to make it happen?
Home-grown electricity right from the sun powers this sweet ride.
Pretty soon, you may have one too. We can help.
Ain't she pretty? The eBay photo that won me over
from the beginning. Buy a solid car or truck with a stick shift
and without a lot of rust. She can have a tired motor.
That's OK. Light weight is good, also reasonable coefficient of drag (wind resistance) and easy-rolling tires help a lot.
We'll do some math later on, but it helps to know a little up front. A gallon of gas produces about 125,000 BTU/hr when burned.
That's about 33 KwH (33,000 watt-hours) of electricity as an equivalent measure. The best gas engine with computers,
tuned-up and at operating temperature gets about 16% of that energy to the drive train. Maybe 15% of your gas
is used for propulsion. How about 90% efficiency? That's more like it.
Gas vs Electric Car (May 2009)
||Cost per mile
||.10 / KWh
conversion, 33 KwH
of electricity ($3.30) takes us almost the same distance at about a
sixteenth the fuel cost
and without making any air pollution. The solar and wind electric here comes from Nature and
the fuel is not transported halfway across the world. Also, no tune-ups, oil or antifreeze, exhaust repairs.
Add to that no warm-up time or tune-ups, the quiet purr of an electric motor and the cool factor
(everyone wants to see under the hood), and she's a winner all around.
The BEFORE picture
kind of a project is not for the squeamish. If you are good with
power tools and unafraid to modify
(chop, bend metal, cut big holes and make replacements for supporting members you removed, and you are comfortable
working around high voltage, sharp metal and many other hazards, you are the guy for the job. Not everyone is an expert
in many disciplines. Our specialty is electronic controls, so much of this was not new but offered some
challenges to be innovative. For the major mechanical systems we asked for help. Rite Engineering in Franksville
answered the call to couple the electric motor to the transmission, mount the motor to the frame, and contracted
out the battery box sheet metal works to Jensen Metals, also in Franksville. T'NS Machining in Muskego, WI
loaned us one of the owners, Scott for a couple long evening sessions to make the boxes fit and securely mount them.
was no small feat, as we put 900 pounds of
batteries in two boxes UNDER THE HOOD, along with the motor,
speed controller, wiring and safety add-ons. Power steering remains the same, belt-driven from the motor (tail shaft),
and power brakes use vacuum from a new electric pump since there is no engine vacuum any more.
(The power steering now has it's own DC motor, and twenty of the 46 batteries moved to the rear August 2009.)
up-to-180 volts DC from the batteries is
stepped down to 13-14 volts by a DC-DC converter to run the headlights,
wipers, radio, and all the usual 12 volt conveniences. Under the flap where the gas filler was, we added a recessed plug
for 220 volts in to a charger. 'Fill her up' turns into 'Plug her in'. Much of this will become clearer through the photographs.
The point is, this is not a plug-and play kit type of conversion. We plan to engineer for each vehicle and its owner the best solution,
without making trade-offs, meeting the goals we set 100% from the beginning. (A Corvette is next!)

OK, here is the motor:

Man, that's a big battery box - firewall to

On June 23
with only 500 miles on the elecrtic conversion, our motor failed : an
armature to frame short circuit.
Oddly enough, this was on the return trip from the scrap yard where we got all of $8 for the old metal...
Motors told me this is a rare occurrence, only the fourth
one they know of. We hope they're right !
It took us 8 hours to unpopulate the battery trays, wiring and remove the motor from the transmission and many mounts.
A truck to New Hampshire picked up the motor; We will post updates as we use the time to make other improvements.
The front batery box (under the bumper) will disappear, power steering will be made electric, and a new bed liner too.
EV America is where we
bought the motor and controller, and many other components.
Bob Batson and Bryan provide great technical assistance, customer service,
and the best documentation we have ever seen ! Contact them and you will be pleased too.
NEWS FLASH 2:

we were able to cruise around the neighborhood and shake the dust off of her from a month in the garage.
had to gut the engine compartment - batteries, battery box,
wiring, motor , mounts ,
transmission alike to send the motor in for repair.
Advanced DC Motors cooperated and not only fixed it under
warranty, but paid shipping both ways.
The motor was made in March 2009, the month we bought it. Works OK now. Thanks for the warranty.
beast was gutted, we moved some of the batteries (20 cells) to the rear
where the gas tank used to be.
Seems only appropriate. Since that is 13 feet away, we had to extend the 500 amp runs of wire. Not easy.
Quick Cable of Franksville came to the rescue with enough 4/0 wire for double runs (4 conductors),
and the appropriate connector lugs to make elegant connections at each end.
