Original tachometer in Saturn cluster was made to work with the electric motor conversion.
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…
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…
First let me say that the following discussion is what I have tried to do to make the original tachometer work in the SS Saturn EV. Up to this point it still does not work. But as Thomas Edison said “I have not failed. I’ve just found 10,000 ways that won’t work. ” Original Crank…
