(Continued)Step 13.a .b .Step 14.a.b.Step 15.c .Disconnect wire, connecting starter motor relay to starter solenoid.Using multimeter, set to 200 ohm scale, check for continuity in wirebetween start motor relay and starter solenoid.(Model 609-A)If reading is 1 ohm or less, go to step 12.If reading is more than 1 ohm,replace wire (paragraph 2.17).Disconnect cable connecting starter motor to battery.Using a 12 voltpower source, energize connection.Put the engine switch in startmode.Using multimeter, set to 20 vdc, measure voltage of start alarmrelay outlet.(Model 609-A)If 12 vdc or more is measured, replace starter (paragraph 2.21.18).If measurement is less than 12 vdc, replace start alarm relay(paragraph 2.15.10).Hold start switch to start position and check for 24 vdc at starterpower input terminal.(Model 609-C)If 24 vdc is measured, replace starter (paragraph 2.21.18).If 24 vdc is not measured, replace start pilot relay (paragraph2 .15 . 1 0 ).Notify direct support maintenance.2. ENGINE CRANKS, BUT WILL NOT START.Step 1.a .b.Step 2.Step 3.Step 4.Check battery voltage for Model 609-C at control panel.Using multimeter, set to 20 vdc, check battery voltage.If 12 vdc (24 vdc on Model 609-C) or more is measured, notify directsupport maintenance.If less than 12 vdc (24 vdc on Model 609-C) is measured, recharge orreplace battery (paragraph 2.15.3).Check air filter for cleanliness or air inlet for obstructions.Clean or replace air filter (paragraph 2.14.1/2.14.2/2.14.3).Remove obstructions from air inlet.Visually inspect fuel lines for damage or leakage.Tighten loose fuel line connections.Replace damaged fuel lines (paragraph 2.21.2).Visually inspect to see if drain plug on primary fuel filter isleaking, clean, or missing.Replace primary fuel filter (paragraph 2.21.4/2.21.5).2-31a .b .a .b .a .b .
