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.

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.

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

following specifications:

Engine mounted NDL alternator: 45-55 Ft-Lbs Frame mounted NDA, NDM alternator: 40-50 Ft-

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.

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.
