A Very Productive Day

Yesterday I started by battening down the crossmember which supports the front of the batt boxes. The I had to figure out a way to get five wires from the engine comaprtment to the center console. I did this by pushing the wire loom wrap over the two wires I had already fished through, then I pushed a wire through. It was somewhat difficult but it went through. A brilliant Idea occured to me that I could tie a string on the next wire I fished through and use it to pull the rest through. Uhhhh… so I already had one in there, now I was going to fish another through with a string… OK it was early, I was still working on my coffee, long story short I did tie a string to the wire that was already fished and pull it back out. Tied all of the wires i needed in the console and pulled them through the loom wrap. Worked like a charm. Then I hooked up the brake transducer… let me explain… An AC setup has built in regenerative braking ie: when you take your foot off the accellerator pedal the controller tells the motor it is now a genarator and pushes some current back into the pack, sounds great except I found while driving EV1E that I did not use Regen most of the time (EV1E has a switch to shut it off) because it slowed me down instead of allowing me to coast and regen really didnt give that much back to the batteries compared to the amount of inertia I was losing. So through trial and error I discovered that I had more range if I could allow the car to coast when I took my foot off the pedal. I still see the value in regen but only when your applying the brake. Solution: use a brake transducer so that when you press the brake pedal it activates regen, that is when you actually want to slow down anyway. Then by programming the Curtis1238 controller I can adjust the amount of regen I use. So that being the principle I set to work. I’ve installed a brake transducer in the brake line right before the proportioning valve. All I had left to do was connect the three wires coming off of the transducer. Since I am not the first to come up with this idea, I only had to look at the schematic to see how to accomplish this. So now I just have to Install the DC/DC converter when it arrives (hopefully tomorrow) and the beast will come to life and breath electrons. That and adjust and bleed the brakes, so when I drive her off of the blocks I hopefully will not wipe out a 59 T-Bird, 95 Jaguar XJS, and a 73 Porsche 914 all in one whack!
