Field Trial Alternator Installation Instructions for Trailer/Rail Units These Instructions are for the Following Kits
NOTE: It is important to identify the appropriate alternator/pulley for the application. If the -01(Frame Mount) or -05 (Frame Mount) alternator is installed onto a unit that requires -00 or -03 (Engine Mount) alternator, the alternator may not charge properly. The pulley is 25% larger, resulting in it turning slower, which can delay the D+ signal and give a false Alt Aux Alarm or cause the starter to stay engaged longer than required or some other false alarm.

1 22-01327-00 1 ½” Shrink Tube 1 30-01114-50 Service Kit A (includes the following:)
2 – M5 Nuts 1 – M6 Nut 1 – B+ Post Cap 1 – Ring Terminal (for M5 Post)
1 62-SKA-10163 Follow The Fleet Orange Tag 1 N/A 1/4” Ring Terminal 1 N/A Cable Tie 1 98-50261-00 Instructions
INSTRUCTIONS NOTE: These instructions are to aid in the removal & installation of trailer/rail unit alternator. 1. Turn OFF RS/SROS Switch. 2. Disconnect and isolate the negative battery cable
from the battery. 3. Loosen adjustment slide bolt and pivot bolt to relieve
belt tension. Remove and save slide bolt for alternator reassembly.
4. Inspect alternator belt. Replace if belt is worn or
damaged.
5. Remove alternator mounting/pivot bolt from unit & remove alternator. Save bolt for alternator reassembly.
6. UNITS WITH ADVANCE MICRO ONLY: Before
installing the new alternator, remove the orange D+ wire from the alternator. The D+ is not used on Advance Micro controlled units. See figure 1.

7. Using the supplied cable tie, attach the ¼” ring
terminal and Follow the Fleet tag to the alternator. (This step 7 may have already been done for you) Slide the cable tie through one of the openings in the black plastic cover, 180° from the D+ terminal. Make sure the Follow the Fleet tag is pointing away from the alternator. This will ensure the tag is not interfering with the cooling of the alternator. Cut off excess cable tie end. See Figure 2.
NOTE: The extra ¼” ring terminal is provided in case the field trial alternator fails & the current production alternator needs to be re-installed.
Figure 2
8. Install new alternator in unit by reusing previously
removed bolts. Tighten bolts finger tight. 9. Install belt on alternator and tighten belt to the
Lbs 10. Tighten the adjustment slide bolt (5/16” -18) to 15-16
Ft-Lbs & the pivot bolt (1/2”) to 80 Ft-Lbs. 11. Cut the B- terminal off of the harness. See figure 3. 12. Remove and discard the boot from the B- wire by
cutting the cable tie and sliding the boot off. See figure 3.
Remove D+ wire if installing on Advance Micro units only.
D+ Terminal
Attach ring terminal & tag with cable tie here.
Cut off excess cable tie end.

13. Install shrink tube & M5 (#10) ring terminal included
in Service Kit A on the B- wire (previous ring terminal is too large to fit between the anti-rotation tabs on the cover). See figure 4 for proper crimp.
Figure 4
14. Attach the B- ring to the B- alternator post and
torque the M5 nut to 40-50 In-Lbs. 15. Remove the B+ boot from the B+ wire by cutting the
cable tie and sliding the boot off. DO NOT CUT OFF THE B+ TERMINAL.
16. Cable tie the boot to the B+ lead. Should the current
production alternator need to be installed again on
the unit, the boot will need to be installed over the B+ terminal again.
17. Install the red B+ post cap loop over the B+ wire with
the “cup” or open end pointed toward the end of the wire.
18. Attach the B+ ring to the B+ alternator post and
torque the M6 nut to 62-80 In-Lbs. 19. Put red glyptol on B+, B- & D+ (L) posts and nuts.
Glyptol insulates & prevents corrosion of the exposed terminals. See figure 5.
20. Press the B+ cap onto the B+ post while the glyptol
is wet. 21. UNITS WITH SUMMIT MICRO ONLY: Connect the
D+ connector (orange wire) to the mating connector on the engine harness.
22. Reconnect the negative battery cable. 23. Start unit and verify alternator is charging battery.
