(a) Disconnect connector.
(9) Test the control box as shown in figure
(b) Using an ohmmeter, set scale to Rl
and read across the circuit breaker. With the cir-
cuit breaker in the closed position (ON), the reading
should be zero(0) ohm.
(c) Open the circuit breaker (OFF), set
the scale to R100, the reading should be infinity.
(d) Connect to a circuit which will drive
23.0 amps at 28 Vdc.
Circuit breaker should not
trip. If it trips, replace per paragraph 17-5.

(a) Disconnect connector.
(b) Using an ohmmeter set the scale to
RI. Check for continuity between terminals, 1-2,
17-5 and table 17-5. If control box fails test check
wiring. (Problem must be in wiring since the com-
ponents have been qualified in paragraph 17-18b(l)
thru (8)).
c. Heater Test.
(1) With the control box energized, check for
230 Vac across the terminals on heaters number 1
and 2.
(2) With the control box deenergized, check
for continuity in each of the heating elements. Re-
place if defective.
