  If your Champion Portable Generator cranks but doesn't start, consider these possibilities: there may be an active fault code (identify and correct the fault code, then reset); the fuel valve is turned off (turn on the fuel supply); there is insufficient fuel pressure (perform a manometer check to confirm fuel pressure to the fuel regulator); the battery is weak (recharge or replace the battery); the oil level is low (check for oil leaks and add oil if necessary); or the spark plug wire is disconnected (connect the spark plug wire).

Why does my Champion aXis CONTROLLER Portable Generator HSB start and then suddenly stop?

  Your Champion Portable Generator HSB might start and then suddenly stop due to an active fault code (identify the fault code, correct it, and reset); insufficient fuel supply (perform a manometer check to confirm fuel pressure to the fuel regulator); low oil level (check for oil leaks and add oil if necessary); the generator being overloaded (turn off standby circuits for the house, reset the fault, and place the unit back into AUTO and ATS mode, then turn on standby circuits); or the engine experiencing a high/over temperature shutdown (check all intake and exhaust ventilation around the HSB, remove all debris, and let the HSB sit for 30 minutes to cool down).

  If your Champion Portable Generator engine starts but runs rough, consider the following: insufficient fuel pressure (perform a manometer check to confirm fuel pressure to the fuel regulator); wrong fuel jets (check jets for NG or LPG, change to correct Master Mixer fuel jets); a faulty spark plug or loose spark plug wire (change the spark plug, set the gap, and connect the wire); a plugged air cleaner (clean or replace the air cleaner); or the generator being overloaded (remove one or more loads).

Why won't my Champion aXis CONTROLLER Portable Generator engine crank/turn over?

  Eric JohnsonAug 29, 2025
  Your Champion Portable Generator engine might fail to crank or turn over due to several reasons: the HSB is in “OFF” mode (place the HSB controllers in the AUTO position); the battery is not connected, loose, or has corroded posts or wires (connect the batteries according to the owner’s manual, clean and tighten the battery connections); the battery is not charged or has a low charge (recharge or replace the battery); or there is an active fault code (identify the fault code, correct it, and reset).

  If your Champion Portable Generator has no AC output, check if the circuit breaker is in the “OFF” position (turn on the breaker); if the main circuit breaker is in the “OFF” position (turn on the breaker); if the transfer switch breaker is in the “OFF” position (turn on the breaker); and if the standby breakers are set in the “OFF” position (turn on the breaker).
