2/21/2020 Campaign #4035: Fix for C100D2RE Generator Set Paralleling Control Wiring Issue Technical Service Bulletin Technical Service Bulletin: TSB190225 Released Date: 19-Feb-2020 Campaign #4035: Fix for C100D2RE Generator Set Paralleling Control Wiring Issue Campaign #4035: Fix for C100D2RE Generator Set Paralleling Control Wiring Issue Warranty Statement The information in this document authorizes specific changes to the repair practice for failures covered under product warranty coverages. Contents Product Affected C100D2RE Issue When a C100D2RE generator set is attempted to parallel with a C150, C200 or C275 generator set, the B+ (24 VDC) on the two units short with each other, as a result of which the units cannot be paralleled, and temperature of the paralleling cable rises. Root Cause: Due to a design error in C100D2RE generator set harness, paralleling C100 with any other models causes the B+ (24 VDC) from one unit to be shorted to B+ on the other unit Verification/Confirmation Confirm if the unit has this issue by checking in the list of affected generator set serial numbers. See Table 2. Resolution On the harness of C100D2RE (PN: A054R546) shown in Figure 1 below: 1. Swap P70-A and P70-B 2. Swap J40-1 and J40-2 Service Instructions Follow all the necessary safety procedures along with Lock Out Tag Out. On the harness of C100D2RE (PN: A054R546) shown in Figure 1 below: https://quickserve.cummins.com/qs3/pubsys2/xml/en/tsb/2019/tsb190225.html 1/10 2/21/2020 Campaign #4035: Fix for C100D2RE Generator Set Paralleling Control Wiring Issue 1. Swap P70-A and P70-B 2. Swap J40-1 and J40-2 The harness is in the front panel inside the top rack of generator set. To locate connectors P70 and J40 with respect to the harness, refer to Figure 2. Figure 1, Harness A054R546 with P70 and J40 highlighted https://quickserve.cummins.com/qs3/pubsys2/xml/en/tsb/2019/tsb190225.html 2/10 2/21/2020 Campaign #4035: Fix for C100D2RE Generator Set Paralleling Control Wiring Issue Figure 2, Location of connectors P70 and J40 on harness 1. Swapping connections of P70 connector (PN: 0323-1637) requires a Terminal Remover tool (refer to Figure 4 for examples) to remove the wires and reconnect them in the right location. Unplug the side clip on P70 connector as shown in Figure 3, before inserting the tool to remove wire connectors. https://quickserve.cummins.com/qs3/pubsys2/xml/en/tsb/2019/tsb190225.html 3/10 2/21/2020 Campaign #4035: Fix for C100D2RE Generator Set Paralleling Control Wiring Issue Figure 3, P70 Connector Figure 4, Terminal Remover Tools https://quickserve.cummins.com/qs3/pubsys2/xml/en/tsb/2019/tsb190225.html 4/10 2/21/2020 Campaign #4035: Fix for C100D2RE Generator Set Paralleling Control Wiring Issue 2. J40 connector is a Deutsch connector (PN: 0323-2334) and the wires (size: 16 AWG) can be removed by removing the wedge (PN: 0323-2333) with a picker (refer to figure 5) and repositioning the wires in the right location. Figure 5, Picker to Remove Wedge Confirm the fix performed above by checking for continuity on the terminals between harnesses A054R544 (Figure 6) and A054R546 (Figure 1) indicated in Table 1, by using a multimeter. Note : The reworked connectors should be plugged back and battery switch should be in the OFF position to check for continuity.

No. Terminals Resistance value required to indicate continuity 1 From J66A-12 to K23A-1 0 -1 ohm 2 From J66A-13 to K23A-2 0 -1 ohm 3 From TB3-5 to K20A-2 0 -1 ohm 4 From TB3-11 to K20-14 10k ohm https://quickserve.cummins.com/qs3/pubsys2/xml/en/tsb/2019/tsb190225.html 5/10 2/21/2020 Campaign #4035: Fix for C100D2RE Generator Set Paralleling Control Wiring Issue Figure 6, Harness A054R544 showing location of connectors J66A and TB3 After the resolution is applied, put a green dot on J40 and P70 connectors as well as on the master label for A054R546 with a permanent marker. If the fix is done in-house, add an extra green dot on the shipping box. This will help identify repaired units and avoid misconnecting in future.
