In response to the above:
I can confirm the Pinout. Car logic seems to be a bit more demanding, than its conventional counterpart. Applying 5V between Pins 1 and 4 for me lowered the Coil resistance read between 2 and 3 from about 16.000 to 8.000 Ohm with a second external transistor in Darlington Configuration. I used a TIP122 which can drive up to 4 A. I was limited by my usb powersupply though. I assume you would have a larger voltage drop, when applying more current. With a 250 Ohm resistor you will protect your circuit, through limiting the current to about 20mA. If you dont use it, you might burn your logic. I did the same when driving the sparkplug with an Arduino. Driving it directly gave me a Resistance drop to 13.000 and a super tiny spark after switching off the arduino. Works well in Darlington Conf with TIP122. Thanks so much for the Pinout!! |
