Troubleshooting
12Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Engine governing system does not function (system inoperative) — Step 1: terminals E(+) & F(-), normal reading battery supply voltage (12 VDC) | DC battery power not connected; blown fuse; low battery voltage; wiring error | |
| Engine governing system does not function (system inoperative) — Step 2: terminals A(+) & B(-), normal reading 0-3.9 with speed trim, 7.1-7.9 without speed trim | Speed trim shorted or miswired; defective unit | |
| Engine governing system does not function (system inoperative) — Step 3: terminals C(+) & D(-), normal reading 1.0 VAC RMS min. while cranking | Gap between speed sensor and gear teeth too great; improper or defective wiring to the speed sensor; defective speed sensor | Check gap; resistance between D & C should be 30 to 1200 Ω |
| Engine governing system does not function (system inoperative) — Step 4: terminals E(+) & H(-), normal reading 0.8-1.5 V while cranking | Wiring error to actuator; defective speed control unit; defective actuator | |
| Engine overspeed — Test 1: Do not crank, apply DC power to the governor system | Actuator goes to full fuel | Then disconnect speed sensor terminals C and D; if actuator still at full fuel — speed control unit defective; if actuator at minimum fuel position — erroneous speed signal, check speed sensor cable |
| Engine overspeed — Test 2: Manually hold the engine at the desired running speed, measure the DC voltage between terminals E(+) and H(-) on the speed control unit | If the voltage reading is 1.0 to 1.5 VDC: speed adjustment set above desired speed; defective speed control unit | Turn counterclockwise |
| Engine overspeed — Test 2: Manually hold the engine at the desired running speed, measure the DC voltage between terminals E(+) and H(-) on the speed control unit | If the voltage reading is above 1.5 VDC: actuator or linkage binding | Replace actuator |
| Engine overspeed — Test 2: Manually hold the engine at the desired running speed, measure the DC voltage between terminals E(+) and H(-) on the speed control unit | Set point of over speed shutdown device set too low | |
| Engine overspeed — Test 2: Manually hold the engine at the desired running speed, measure the DC voltage between terminals E(+) and H(-) on the speed control unit | If the voltage reading is below 0.8 VDC: defective speed control unit | |
| Actuator does not energize fully while cranking — Test 1: measure the DC voltage between terminals E(+) and H(-) on the speed control unit; should be 0.8 to 1.5 volts, if not | Weak or undersized battery; actuator wiring incorrect; if voltage is greater than 1.5V, speed set too low | Replace the battery if weak or undersized |
| Actuator does not energize fully while cranking — Test 2: momentarily connect terminal E to H; the actuator should move to the full fuel position | Actuator or battery wiring in error; actuator or linkage binding; defective actuator | Replace actuator |
| Engine remains below desired speed — Test 1: measure the actuator output, terminals G & H, while running | If voltage measurement is within 1.5 volts or more |
