Nothing special here. The PlanePower 70 amp interally regulated alternator bolted on per the instructions. I set the blet tention to 14lbs using the torque slip method. I did have a quandary on how to safety wore two of the bolts as there was no engine structure or hardware near the bolts to run the safety wire to. A quick post on Van’s returned the simple (and in hindsight obvious) solution. Just drill a small hole in the tension arm near the bolt and tie off the safety wire there.
