Hi Grumpy, its getting a bit confusing i know. Have done as you suggest and diconnected kill wire from ignition module. With the ignition off the tester showed 0.00, with the ignition on the tester shower 0.44. As far as i can figure out i shouldnt have power going to that wire but coming that wire once motor has started, is that right.
To answer a quick question, this Tecumseh motor was originally on this base MTD Yardmachine, the one it is on again.
