Thats very helpful, what would you consider an acceptable ohm reading for a power and ground wire. i did check voltage at the box and its the same as battery voltage but i didn't ohm the power wire or the ground. however i will say we've had 2 other motors in this car before and this one was in in september of last year but couldn't keep head gaskets in. but the half pass and couple hub dyno pulls it made didn't display this issue which really makes me think the box took a hit and or there is a fuel issue but our 7al2 is 22 years old so we decided to go ahead and upgrade and its getting a grid system this weekend with a new hvh 2 coil and we will go from that point.
