A small set of needle nose pliers put the needles in very easily. Then I used a DVOM to make sure they had contact (measured from pin to needle) and plugged it back on the IACV. One needle on each coil "hot" lead (sorry, can't remember the colors right now and the book is at home).
Thing I connected a scope probe to each needle. Then connected the probe grounds together and connected them the negative battery terminal as Max suggested. All was well. Nice 12v pulses.
Speed will post up the videos when he gets them. I sent him 2, but one may have gotten lost in the ether. I may have to resend.
Yes, I received only the 10 seconds video which is very good, nice video of the start up signal. Nice work, I also like the video that Max made (if I am right) with the leds connected. If I connect the probes ythe same way as you did I have the same signal from 0 to 12V, but if I connect the probe to each end of the coil (Bl/Y to Bl/O) I get a signal from -12V to 12V. I am wondering why. By the way, which is the hot lead of the coil? I get 12V pulses coming from both leads of each Coil (Bl/Y to chassis or Bl/O to chassis). Does not matter I disconnect the IACV or not, each lead in reference to chassis ground is getting a 12 V pulse when setting ignition to ON.
