NOTES ON CRIMPING - AH00.19-P-1000-09A
Model 124, 126, 129, 140, 163, 164, 168, 169, 170, 171, 199, 202, 203, 208, 209, 210, 211, 215, 216, 219, 220,

1. Check crimped connection for deformation and ensure that the wires fill the crimp tab correctly (cross-
section of enclosed wires).
Correct crimped connection (A):
The strands of the cable are evenly enclosed.
The crimp tab is evenly shaped.
Incorrect crimped connection (B):
The crimp tab has an incorrect cross-section and is not full enough.
Incorrect crimped connection (C):
Individual wire strands are outside the crimp shackle.
The crimp tab is too full.
Incorrect crimped connection (D):
The crimp claws touch the bottom of the crimped fitting.
The crimp tab is too full.
The crimp tab is deformed and therefore damaged.

2. Check crimped connection (ensure all wires are enclosed correctly).
Correct crimped connection (A):
Leads (3) enclosed correctly by the tab (2).
Insulation is enclosed correctly by the tab (1).
Incorrect crimped connection (B, C):
Leads (3) are damaged due to deformed tab (2).
Insulation is pinched by deformed tab (1) and damaged.

3. Check crimped connection (ensure that wires and insulation are correct length).
Correct crimped connection (A):
Correct length of insulation is enclosed by the shackle (1).
Wires (3) are the correct length in the tab (2).
Incorrect crimped connection (B):
Insulation is too short and is not correctly enclosed by the tab (1).
Therefore insulation cannot withstand the required tensile load.
Incorrect crimped connection (C, D):
Wire strands (3) are too long.
Leads (3) are too short.

NOTES ON SOLDERING - AH00.19-P-1000-10A
Model 124, 126, 129, 140, 163, 164, 168, 169, 170, 171, 199, 202, 203, 208, 209, 210, 211, 215, 216, 219, 220,
221, 230, 240, 245, 251, 414, 461, 463
Evenly heat parts to be joined and solder. Avoid heat-dissipating mounts and brackets. The soldering process
lasts between 2 and 4 seconds for the joining of wires and component connections, depending on the cross-
section.
The same time must be fixed up to hardening.
Unnecessarily high heating and associated damage to components must be avoided.
During pauses in soldering, it must be ensured that the soldering tip remains adequately tin-plated.
Surface of the soldering join
Correct soldering join (A):
The solder surface (4) is smooth, shiny, no sharp edges, no interruptions, fluid and free of residues and
oxidation.
Incorrect soldering join (B):
The surface of the solder (4) is matt and uneven, it has sharp-edged ends, interruptions, has not flown, covered
with residue.

Fig. 15: Identifying Surface Of Soldering Join - Correct And Incorrect
Wire position and contour of soldering join
Correct soldering join (A):
The distance (a) between the solder connector (2) and the line insulation is about 1 mm. The soldered area does
not extend beyond the collar of the solder connector (2). Solder flows in a radius in the direction of the line
insulation and surrounds at least 2/3 of the lead outside the solder connector (2). There are no bare copper wires
visible in the soldering area.
Incorrect soldering joint (B):
If the distance (a) between the solder connector (2) and the line insulation (a) is greater than 2 mm, the line is
incorrectly inserted. The solder protrudes beyond the extension line from the collar of the solder connector (b).
The solder flows in the wrong direction, the transition from solder to lead is jagged, the solder surface (3) has
not flown and is thus a dr
y solder joint.

Solder covering and solder quantity for the soldering join
Correct soldering join (A):
The quantity of solder (4) is adequate. Lead of wire (1) is completely surrounded. Solder connector (2) is not
covered with solder (4) around the collar.
Incorrect soldering join (B):
The quantity of solder (4) is inadequate. Lead of wi re (1) is not completely surrounded. Single wires are not
incorporated by the solder (4).

General
An attempt should be made to restor e the cable protection to its original condition after all repairs to wiring
harnesses.

In areas exposed to particularly high stresses (dampness, scouring), additional safety precautions may however
be required.
The following measures are recommended depending on the application.
Protect repair area using:
Heat-shrinkable tube
Corrugated tube
Wrapping with fabric tape
Spaghetti insulation
