6-6. ALTERNATOR INTERCHANGEABILITY
General Information:
Alternator failure will degrade the vehicle’s combat operations. Emergency usage on
battery power is only operation possible, but will require frequent recharging from
another vehicle or an outside power source. The alternator should be replaced.
Limitations:
None
Personnel/Time Required:
2 soldiers
4 hours
Materials/Tools:
Cannibalized alternator
Corresponding regulator
Other Options:
Vehicle can be driven without alternator
Procedural Steps:
1. Remove power pack.
2. Obtain alternator from another vehicle or unserviceable engine.
3. Examine the replacement alternator to determine if it is an exact replacement. If
the exact replacement cannot be found, the AVDS 1790-2D alternator can be
interchanged with the AVDS 1790-2C alternator.
NOTE
Interchanging alternators requires the exchange of engine wiring harnesses 7722353 and
1165541 (AVDS 1790-2C) with 11682724 and 11672723 (AVDS 1790-2D). The voltage
regulator must also be changed if changing the wiring harnesses and alternator (See
figure 3- 1).
Interchanging alternators also requires the installation or removal of oil cooled
alternator cooler hoses or air cooling ductwork.
Utilize as many parts as possible from
the same source.
