i have a obd0 ls dizzy, and i'm not getting spark. i had a pretty good lesson on the internal workings of one since i took 2 apart to make one. anyway, on the coil there is the positive terminal and a negative one. I'm not getting any kind of reading on my multimeter. there is a 4 prong/post thing that have 4 wires going to it. my question is what is the order in which those wires go? i know one of the 4 wires is from the crank position sensor but not sure which post/prong it goes on. please help me
