Conversion TimeApproximately 80 hours labor over the past 6
years. The majority of that, probably 60
hours, in the first quarter of 2014.
Additional FeaturesClutchless

Volvo brake booster vacuum pump. No vacuum reservoir.
A micro-switch on the brake pedal turns the pump on
only when needed. Works great.

DC power module: EUMFD60Y28A
Panasonic FD series full brick DC/DC power module
set at 11V. Used to provide the supply voltage
(8 to 30 volts) for the Kelly motor controller.

AutoCraft Automotive Battery
Group Size 75/86, 650 CCA
to run the chassis electrical.
Many hours of labor and consultation invested by Joshua
English of J&E Performance Motors formerly of Stillwater OK.

1/14/2014: Batteries ordered from Hybrid Auto Center.

1/16/2014: Trial fit motor and trans-axle in the car.

1/21/2014: Received batteries from Hybrid Auto Center and
ordered Elcon charger from EVolve Electrics.

1/23/2014: Ordered SOC bar graph meter off eBay.

1/28/2014: Front mount finished and installed.

2/19/2014: Received charger.

2/22/2014: Removed all ICE associated wiring.

2/23/2014: Installed component board, mounted charger,
batteries, controller and fan.

3/09/2014: Wiring done, turned on the power to test.
Controller shows fault code 24 - �Throttle signal is higher
than the preset dead zone at power on.� Curtis PB6 pot-box
is reverse of what Kelly controller is expecting to see.

3/10/2014: Reworked PB6 pot-box to work with Kelly

3/11/2014: Installed axles, filled transaxle and topped off

3/12/2014: First drive. Ran out of juice 1/2 mile away from
home and had to be towed in, establishing the range at 20
miles. The Kelly controller has the low voltage cut off
preset at 50V, just about right for these batteries. Any
voltage level under 50v was having trouble making speed

3/14/2014: Removed fuel tank.

3/23/2014: Ebay (rcfuther) 84v bar graph "fuel gauge"
worked for one round and quit. Further communication with
the vender yields a chart that details the useful range of
the bar graph. It is actually an 86v gauge that has a 14v
range, pretty useless in my application. This explains why
the bar moved so quickly to the left. However they could not
explain why the bars would not come back to the right after the
pack was depleted and recharged.

4/26/014: Ordered Volvo 12V vacuum pump for power brakes.

5/10/14: Volvo vacuum pump installed, power brakes

5/28/14: 1000 miles

7/20/2014: Ordered DC to DC converter from Kelly Controller
