Electric Vehicle ( EV ) Conversion 11-19-2007

Lloyd helped me load 800 pounds of batteries onto the rear battery packs.
OK, he did most the heavy lifting, but I'm more of a management/supervisor type anyway.

Later, Paul couldn't wait another day for me to wire all of the battery management boards and resistors, so helped me cut, lug, and crimp cables on the condition we would make the wheels spin.

Bob, did the honors after spending ten minutes testing my batteries, checking my connections, and letting me know I connected the front pack to the rear pack wrong.

What happened was that I had labeled the 2 cables (1 red and 1 white) and forgot that the red was to go from Positive in the front pack to Negative in the rear, and the white from the negative connection in the front to positive in the rear. Well it took just 2 days for me to forget and I hooked up the red labeled cable in the rear to the positive and the white to negative. No sparks, but I wasn't getting the expected voltage.

Once we switched the cables around in the Anderson connector, we were good to go.

Bob did the honors of spin testing the motor and wheels. 1st with 4 of the batteries from the rear pack.




We weren't expecting that big of a spark, and didn't want to burn the motor out, so decided to lessen the voltage before connecting the jumper cables again.
Next we tried it with 24 Volts.

I'm pretty stoked, as before today I had not tested the motor. I had seen the rear shaft spin while rolling the car, but not via electrical power.
