Transformer and Resistor

Figure 4-20.

(a) Testing.

(1) Refer to wiring diagram (FO-1) and use a multimeter to test the

transformer for continuity through both the primary winding and the secondary winding. If

no continuity exists through either winding, replace the transformer.

(2) Use the multimeter to verify the resistor ohms. If measurement shows

other than 10 1 ohm, replace the resistor.

(b) Removal.

(1) Refer to paragraph 4-29 and remove the junction box.

(2) Refer to figure 4-20 and remove the transformer and resistor. Remove

resistor from transformer if either is faulty when tested.

(1) Refer to figure 4-17 and install the transformer and resistor.

(2) Refer to paragraph 4-29 and install the junction box.
