Bistable relay contacts resistance
The comparitor circuit exists in both DPU and the MPU.
They communicate about errors
In a falcon 50, or 200 used DPU-86C
622-7248-001, or -002 after mod
Manual for EFIS-86(1) is
EFIS-86(3) or (13) usses DPU-86L
EFIS-86 (4) or (14) uses DPU MPU86R
In a low SN 50
622-9009-001 or -002 after mod. Is this what gives names on waypoints on MFD?
Target the gear to get WOW
Disconnect the down brace prox (2 on each) to get GEAR NOT DOWN.
Disconnect RA RECV coax cable to get RA 2500 FT.
observe RA 2500 FT on the ADI
Select FID on TXP

For F50 N98DH, the fwd H-Stab, (Normal) motor is P/N 1234-2, S/N 206, monted on Stab Jack P/N 021121-09. S/N 332.
Normla motor is p/n 1234-2
That means the stab jack is compliant with SB F50-267, and SB F50-247.
So, brake current check and instpect and clean are not due at the 12 month check.
Here is some of the early analysis.
you have Stab Jack P/N 021121-01 or 021121-05 or 021121-05 AND Normal motor P/N 1234.
Brake holding check and Check is due at the 12 month AND check and clean is due at the 12 month.
you have any stab jack with stab normal motor p/n 1234-1.Drop out current check is not required. inspectand clean is due at every 12 month check.
POST S/B F50-267
you have any P/N 021121-09 stab jack, with normal motor 1234-2, Check and cleaning not required, drop out current not required.
