1101

Overcrank, starter protection

Engine · Alarm

Alarm 1101 is the Evolution overcrank that limits cranking cycles to protect the starter. The diagnostic table says it triggers if the engine has tried to crank 10 times without starting.

Seen on: Air-cooled home standby generators with an Evolution 1.0 or 2.0 controller.

Likely causes

  • The same no-start causes as 1100, repeated until the controller stops to save the starter.
  • A starter that has already been overheated by repeated attempts.

Checks an owner can do

  1. Stop cranking. Let the starter cool before anyone tries again.
  2. Check only that fuel is on and, on LP, that the tank is not empty.

When to call a pro

Ten failed crank cycles means the starter and the reason it will not fire both need a technician. A dealer fault guide adds that 1101 is the 8 kW and 9 kW form of this limit.
