NOTES CONTINUED
NOTE 1: FOR POTENTIAL FUEL QUANTITY RESISTORS P/N REFERENCE SECTION 3.1.2. ALL RESISTORS ARE REQUIRED TO BE THE SAME PART NUMBER.
NOTE 2: SAE AS4461 REVISION C OR A LATER APPROVED VERSION IS TO BE USED IN THIS PROCEDURE.
1. TRIM RESISTOR LEADS TO 0.25±(0.063) INCH.
2. CREATE A HOOK IN THE REMAINING LEAD ON THE RESISTOR. REFERENCE FIGURE 9 IN AS4461 FOR HOOK CREATION.
3. PREPARE RESISTOR LEAD AND STRANDED WIRE IAW AS4461 SECTION 4.8.
4. USE PROCEDURE IN AS4461 SECTION 5.1.6.1 ALONG WITH FIGURE 8 AND 9 GUIDANCE TO SOLDER RESISTOR LEAD TO STRANDED WIRE(S) AS
SHOWN ABOVE. ACCEPTABLE SOLDER TYPES ARE Sn60 OR Sn63.
5. CLEAN FLUX RESIDUES IAW AS4461 SECTION 4.11.2.
6. INSPECT SOLDER JOINT IAW AS4461 SECTION 5.1, JOINT CAN BE REWORKED IAW AS4461 SECTION 4.11.1. IF REWORK IS REQUIRED, INSPECT

NOTE: DURING THE HEAT SHRINKING PROCESS ENSURE THE RESISTOR IS MINIMALLY EXPOSED TO DIRECT HEAT.
7. COVER SOLDER JOINTS IN 0.5(±0.1) INCH STANDARD HEAT SHRINK, REFERENCE SECTION 3.1.2 FOR P/N OF HEAT SHRINK. ENSURE THE HEAT
SHRINK CONSTRICTS AROUND THE SOLDER JOINT AND CONNECTING WIRE.
NOTE: DURING THE HEAT SHRINKING PROCESS ENSURE THE RESISTOR IS MINIMALLY EXPOSED TO DIRECT HEAT.
8. COVER ASSEMBLY IN 1.25(+0.25/-0.00) INCH STANDARD HEAT SHRINK, CENTER HEAT SHRINK ON RESISTOR PRIOR TO SHRINKING. REFERENCE
SECTION 3.1.2 FOR P/N OF STANDARD HEAT SHRINK. ENSURE THE HEAT SHRINK CONSTRICTS AROUND THE HEAT SHRINK INSTALLED ON THE
SOLDER JOINTS.
