How could ASCB wires break at the splices?

 

Here is the one with heatshrink strain relief after the splices.

here is the failure due to rough handling throughout the years. The ASCB buss splices are so strong they do not flex at all.  All flex occurs right at the beginning of the 24 AWG wire after the splice

Here is another example of a environmental splice broken due to hard manipulation of the harness over the years.

 

Cursed Airplane summary

Summary:
RBTC secondary contacts resistance. This solved Gen Split Problem
Hardware, corrosion at Load Meter Caused indication missmatch.
Cut, burned wire at battery contractor caused battery disconnect in flight.Multiple bad Duncan APU controlles did not help the troubleshooting
Detail:
Swapped CT ‘s on ground lugs at Baggage compartment, cleaned all hardware.
Swapped CT’s at gen B lead in Power panels, cleaned hardware.
Loose bolts at left gen RCR c
Found GCU pin K interconnect erratic when RBTC is tapped with a plastic screw driver.
Replaced both BTC’s as a precaution. This appeared to resolve the problem for a number of
flights.
Suspected Gens might be parallel correctly, with bad indication.
Evaluated D lead voltage on both starter generators. Found exact match from right to left D
lead. Under various load conditions.
Voltages roughly matched 1.2 to 1.6 volts per 300 amps expected (Jerry Cable, Duncan)
Swapped meters, split appeared to swap with meters for calibration.

Meters calibrated good, however, still split 25 in the airplane.

Found mixture of brass
and SS hardware at load meters was causing meter split. Replaced all with brass, and
meters now indicate exact gen load share correctly.

Left battery would intermittently disconnect.  found cut wire from the hot side of the Battery contactor touching lower skin.(batteries are relocated between MLG after Duncan APU install)Left contactor had been replaced previously.

 

Squawk: ____________ Left WS heat Fault light on. Verfied complint. research wire diagrams. accessed Sw heat RCB. Attempted to swap RH RCB. Nuts on terminal galled and will not release from stud.

ordered a replacement RCB for the left side.

what are a few thing that should occur on the flight to input into maintenance

I cannot remember if I sent you the details for the crew….

Some time during the final flight before maintenance…..

Before takeoff be sure to set the FDR gmt and trip number.

1.
fly the autopilot on LAFCS master, and some portion of the flight fly on RAFCS master.

2.  Press FDR event at any time while in flight.

During the final 20 minutes of flight, transmit to atc from the pilots side as well as the copilot side.

After landing

1. Pull “CVR” (or “VOICE RECORD”) and FDR (Or “FLIGHT RECORD”) circuit braker when clear of the runway.

2. For a F900 B, try to retrieve the autopilot fault codes from the ID802.
