[300zx1990ttjdm]

Could some one explain to me how to test ptu i tryed following what the diagram say to do for the S2 ptu but i only get a reading from one side i did one terminal on G pin the other on any of the I1-I6 get 0.63 but from G pin to E1-E6 on other side nothing just says 1 with either red or black terminals on either sides. same goes with E1 to I1 all the way up to E6-I6 just a 1 on multireader i just ordered this from z1 motorsports they say garuntee to be working so im confused am i doing something wrong ive never actually tested electronics before new at using multimeter thanks for any help

I did read that didnt really tell me how to test new style ptu i wasnt getting spark to any cylinders except #1 so i checked my ptu with multi tester from one side of it to the other to see if power was going thru but nothing showed up on tester so i order a used one from Z1 motorsports but same thing i havent tryed putting it in yet just wanna know if its working before i put it on so if no sparks still i know its not ptu am i testing it properly
