after looking at the diagnostic procedures in this forum, I am finding my Gunner 250 does not have an engine warning light on the dash. i have tried to see if any other symbols flash, but nothing seems to project an error code. i have not engine spark. I do not get a start of the fuel pump. I have replaced the ignition coil, the ECU (MT05) and the voltage regulator. I could really use a diagram for the 250 model. i need a place to start checking the electrical system.
