TESTING 1. Use multi-meter (Figure 2, Item 16). Check resistance from circuit 7 terminal end (Figure 2, Item 17) to strap end (Figure 2, Item 18) of fixed resistor. 2. Multi-meter should read 1.6 to 1.7 ohms. If reading is not in range, replace fixed resistor. Figure 2. Fixed Resistor – Testing. END OF TASK INSTALLATION 1. If fixed resistor (Figure 3, Item 9) is to be replaced, grind or cut sleeve (Figure 3, Item 1) off of fuel tube (Figure 3, Item 4). Discard sleeve. 2. Install fixed resistor (Figure 3, Item 9) and new sleeve (Figure 3, Item 1) on fuel tube (Figure 3, Item 4). 3. Secure electrical lead (Figure 3, Item 8) to fixed resistor (Figure 3, Item 9) with screw (Figure 3, Item 5) and nut (Figure 3, Item 10). 4. Secure fixed resistor (Figure 3, Item 9) to heater (Figure 3, Item 13) with nut (Figure 3, Item 7). 5. Secure fuel tube (Figure 3, Item 4), flange (Figure 3, Item 3), and tapping plate (Figure 3, Item 11) to heater (Figure 3, Item 13) with two screws (Figure 3, Item 2). 6. Install end cover (Figure 3, Item 6) on heater (Figure 3, Item 13). Tighten four nuts (Figure 3, Item 12). 7. Secure fuel control valve bracket (Figure 3, Item 14) to heater (Figure 3, Item 13) with two screws (Figure 3, Item 15). TM 9-2350-277-40&P 0029 0029‐2
