Starter Stall
in 912 / 914 Technical Questions
9 years ago
Gentlemen, I have a 100hp 912 ULS powered RV-12. The engine came with the heavy duty starter, and I added the soft start ignition module. It has been flying for nearly 2 years and I have 120 hours on it. The starter will stall 2 or 3 times on the first morning start, after which everything is normal. I keep a battery maintainer on it when it is in the hangar, and typically see 13.4 volts before starting. The stall is not kick back, as the condition does not change, even when cranking with the ignitions in the off position. I hear what mimics an electrical short at the time of the stall. such as zzzzzt. I have cleaned all connections in the circuit and am ready to start component swapping; master, or start relay, or starter. Any thoughts would be greatly appreciated....Tom
