TVS2 Removal
1. Remove the ring terminal from ground as shown in Figure 6-10.
2. Carefully remove heat shrink from the TVS assembly, ensuring not to cut the insulation on the
wire under the heat shrink.
3. If replacing the entire TVS assembly, unplug the 4-pin connector, remove the ground ring terminal
and proceed to step (1) of the replacement. If it is not necessary to replace all of the TVSs,
carefully unpin the failed TVS(s).
4. Apply heat with a soldering iron to opposite end of the TVS assembly so that the bad TVSs can be
removed. Use caution when applying heat to the solder joint to ensure that the remaining TVSs
aren’t damaged.
