(g) Connect the bonding jumper [2] to the overtemperature shutoff valve [1] with the
screw [12], the two washers [13], and the nut [14].
(h) Connect the electrical connector [3] to the overtemperature shutoff valve [1].
SUBTASK 47-11-04-765-002
(2) Use the intrinsically safe approved bonding meter, COM-1550, to measure the electrical
resistance between the overtemperature shutoff valve [1] and the airplane structure (SWPM
20-20-10).
(a) Make sure that the electrical resistance between the overtemperature shutoff valve [1]
and the airplane structure is 0.008 ohm (8 milliohms) or less.
(b) Apply a cap seal of P/S 890 Class B sealant, A50051, to the terminal, fasteners, and bare
conversion coated areas.
H. Operational Test for the Overtemperature Shutoff Valve
SUBTASK 47-11-04-865-002
