KA Q
As an Instructor Pilot and Checkairmen in all KA at some time in my career I have seen the start done both ways. The rule is prior to the Current limiter change to 325amp drop right gen off before start (expecially nicad) and you may never lose the current limiter. Always check after both starts. STC'ed aircraft and those after BB1400 with the newer GCU's very seldome lose CL's, but they do blow from quick starts (high Rt Gen loads) or electrical abuse to the system (inflight engine starts or flight training).
Gen loads for nicads are less than 40 is OK less than 30% on right prefferd.
8000 hours in KA's and counting!
