Trying plugging in a battery cart after landing and before he cycles the BATT switch after shutdown and see if it makes a difference.
This aircraft for the last couple years has had very loud static over ICS during the start sequence up until about 12% N1 then it stops. Static only heard on battery starts. If using Start Stick or APU no static is heard.
Before changing the ST/GEN would recommend opening up the master electrical box in the baggage comp. With this ongoing problem may have a water/corrosion issue with card contacts or relays contacts and its bridging in certain scenarios.
While probably not applicable to this model B3, has the cockpit electrical emergency switch been actuated in recent times?
