Disassembly / Reassembly Procedures
Disassembly Procedure 
Disassemble the Power Sensor by performing the following steps: 
CAUTION Disassembly must be performed in sequence described in the following procedure, 
otherwise damage may be caused to the two gold wires between the bulkhead 
assembly and the Power Sensor Board Assembly. If these wires are damaged, the 
A1 Bulkhead Assembly must be replaced. 
NOTE Every Power Sensor has an individually prepared label on the housing. If more than 
one power sensor is disassembled at a time, be sure to mate the correct Power 
Sensor and housing when reassembling.
Step 1. Insert the blade of a large screwdriver between the two-piece plastic shell at the rear 
of the Power Sensor. Gently pry the sections apart. (See Figure 3-4.)
