As I drive every day in this 100% electric vehicle I ponder questions bigger then me and my grasp of the world. It don’t take much to overload my circuits. What about the future of the automobile in the western world? How much are Americans ready to give up, to save energy? How will we…
Checking the efficiency of the SS Saturn EV is one of the goals I have been working on lately. BTW ……. have over 2,000 EV miles on her. Review some things I have 2 chargers for the pack. One is an on board 115ac volt unit that I now use only to opportunity charge while…
Here I video the Saturn accelerating from a stop, shifting through the gears observing the 4 gauges, from the left are the voltmeter, speedometer, tachometer and amp meter. My wife videoed this after church with me driving. The battery pack had been driven about 9 miles since the last charge. I am not trying to…
Here is the simple wiring diagram for the tach. Seems easy once it’s all over. I guess like after the invention of the wheel or the screw. Make sure, 6 teeth evenly spaced and a sensor like this Cherry that generates what I call a square wave not a analog wave.
Using the Thomas Edison saying again “I have not failed. I’ve just found 10,000 ways that won’t work. ” See : http://www.saturn.lynnautorepair.com/node/210 http://www.saturn.lynnautorepair.com/node/249 http://www.saturn.lynnautorepair.com/node/285 http://www.saturn.lynnautorepair.com/node/304 Well almost 10,000 ways, but now the tachometer is recording the exact revolutions per minute of the DC electric motor. In the other three posts on this issue I…
It is cold you know, especially you Yankees and Canadians know, so I bought one of the oil filled heaters. I plug it in at night, in the back floorboard, turn it on low. When I get up in the morning the insides of the Saturn are nice and warm and stay that way until…
It has been cold like it always does this time of year but more so it seems ( especially with the economy and all). I drive the SS Saturn everyday to work and on weekends. Five degrees f in the morning has not stopped her. Snow, slush and rain either. Maybe lots of snow might…
Dave Koller is another EVer I have been in contact through email about using the original tachometer on the electric conversion job. He assembled an adjustable pulse generator board for me to try out and mailed it. Tonight I tried it out with much success! Next will be to build another board that accepts an…
I Borrowed The Dirt Track Scales from Richard Holmes, one of my mechanics. These are the same scales I weighed the Saturn before the conversion. See Measure Ride Height and Vehicle Weight . I had planned and even told people The Similarly Stimulated Saturn probably weights about 3000 pounds. I was wrong. The scales showed…
I gathered some input about this ‘factory tachometer’ issue today. From last weekend’s journal entry, email response, searching on the internet and a couple of phone conversations I have some info to add. I was able to access another Saturn with factory ICE and get reference tach signals. Dave Koller, who is working on a…
