ECU input to Igniter (ICM) on 1993 Honda Civic DPFI
How do you measure the input from the ECU to the ignitor (ICM) (YEL/GRN wire)??
This input tells the ignitor when to ground the -ve side of the primary coil. My multimeter registers a non zero small voltage when cranking, but since the response is very low on my meter, I don't think I'm picking up the correct voltage. Should I be using a PC oscilloscope? If so so what voltage should I see |
