Hi I have a Txt Pro 2004 with no spark issue and would really appreciate your help/info PLEASE!!! Here is what I have tested so far with the results:- * Plug = 4.03K (BPR5ES NGK). * All Earth Connectors & Coil cleaned plus Frame Bracket. * Coil Primary Circuit (both wires on unit) = 0.90 ohms. * Coil Secondary Circuit (spark plug cap) = 5.04k. * Disconnected Kill Switch wire from Earth/frame/Coil (the white from CDI to black/white on kill switch still connected)
