FixYa: We understand that your problem is: I have a model 4390 ng, 13k it stalls after 10 sec restarts stalls 4 sec after that. I have unplugged both low oil pressure and high temp.no differnce.I am losing power to both ingnition contol moduals 1 & 2 and also power to natural gas valve.It looks like the control board is bad .Can I run 12volts too the ignition coil and ng valve to run the motor.?????
