I am hoping someone has a suggestion that I haven't thought of. I test drove my 88 around the pasture, the transmission was slipping, I shut it off to check out the vital fluids, and the transmission fluid was low. The next day I bought fluid, and added it. It has no spark now. I have checked, and it has power on the yellow wire, and the black wire is grounded. Nothing makes sense to have gone out with no warning. I hope some one has an idea I haven't thought of.
