FUSE BLOCK DEFORMS
Model and Year:
1988-90 SI (LLV) POSTAL VEHICLES
Some 1988 to 1990 LLV postal vehicles built prior to August 3, 1990, may exhibit a condtion where the fuse block is partially deformed due to heat
generated by continuous operation of the hazard flasher. This condition may be corrected by the repositioning of the hazard flasher to a remote location.
SERVICE PROCEDURE:
1.
Disconnect positive battery cable.
2. Remove old flasher.
3. Back out terminals for circuit 140A (orange wire) and circuit 27 (brown wire) using a small flat screwdriver or pick. Using the same tool, raise the
locking tang on the back of the terminal.
4. Cut electrical tape used to wrap main wiring harness a sufficient amount to provide 2 to 3 inches of flasher wiring for relocation.
5. Insert terminals of circuits 140A and 27 into new connector (P/N 2973385).
6. Install electronic flasher (P/N 15504673) into the new connector.
7. Using nylon ties, strap the connector and flasher assembly to the wiring harness that runs above the fuse block. Verify that the relocated flasher and
all wiring is secured so it does not cause interference with the throttle linkage.
8. Reconnect battery cable.
9. Test operation of hazard flasher system.
