Service manual for trailblazer 302 - Miller Trailblazer 302 Welder Generator 907217 907216

the Trailblazer 302 diesel, has a fuel level sensor that tells Control PCB2 if there is fuel in the tank. PCB2 sends a signal to CR1, which lets voltage go to the Fuel Solenoid. If the sensor is bad, PCB2, CR1, or the fuel solenoid, fuel will not get to the engine. I am including the manual for the Trailblazer. Now keep in mind, the circuit may be a little bit different based on serial number. In the center of page 46 will be the fuel circuitry. Good luck https://www.millerwelds.com/files/owners-manuals/O217454U_MIL.pdf

FUEL PUMP ? FUEL FILTER, GAS CAP NOT VENTING, ENURCHIA VALVE.

Both sets of the 120? If both of those are there (all 4 outlets), then the machine is producing 220v. So get a flashlight and look into the holes on the 220 receptacle, or check the wires on the backside of the receptacle. All that 220 is, is two 120 volts out of phase.

www.millerwelds.com have the serial number handy. Click on service, then owners manuals and follow the directions.

Check your machines fuses. For location of fuses look into your owner's manual.

If this was useful to you please vote. Thank you!

If you have owners manual I would locate the low oil safety switch and replace it. You can temporarily bypass the switch to verify that is the problem before buying new parts but I would not leave it that way. Use for diagnostic only. Thank you
