Troubleshooting
6Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Low AC Voltage at Startup | Loss of residual magnetism in the exciter stator lamination | Restore magnetism: attach leads to a 12VDC battery with a diode in one lead; run the generator at rated speed, no load; briefly (maximum one second) connect positive lead to control board terminal F1: P17-1 and negative lead to control board terminal F2: P17-2 |
| Unstable Voltage (No Load) | Engine governing unstable | Check for engine governor hunting with a frequency meter or tachometer, or cyclic irregularities in the engine with InPower; if any engine DTC fault codes are present, troubleshoot them using the E-Controls manual; check fuel supply pressure to ensure that it is consistent; ensure that the throttle assembly moves freely, clean it if necessary; check the spark plugs for buildup, ensure that a spark is present at each cylinder, repair or replace them if necessary; check for any exhaust restriction, clean or replace components as necessary; check for an intake leak, repair or replace components as necessary; check for proper function of the crankshaft and camshaft position sensors, and the wiring to the ECM from the sensors, repair or replace components as necessary; check the fuel mix control valve for proper operation, such that it can move freely and easily, clean or replace the valve if necessary |
| Unstable Voltage (No Load) | Loose or corroded connections | Check electrical connectors on terminals on the control board; check auxiliary terminals for loose connections; repair or replace as necessary |
| Unstable Voltage (No Load) | Intermittent ground on machine | Megger test all the windings, including the exciter stator; low insulation resistance can affect the PCC (disconnect the PCC before megger test) |
| Unbalanced Voltage (With Load) | Alternator loads unbalanced | Check that loads are balanced on each leg of alternator output (L1, L2, L3) |
| Unbalanced Voltage (With Load) | Engine governing unstable | Check for engine governor hunting with a frequency meter or tachometer, or cyclic irregularities in the engine with InPower; if any engine DTC fault codes are present, troubleshoot them using the E-Controls manual; check fuel supply pressure to ensure that it is consistent; ensure that the throttle assembly moves freely, clean it if necessary; check the spark plugs for buildup, ensure that a spark is present at each cylinder, repair or replace components as necessary; check for any exhaust restriction, clean or replace components as necessary; check for an intake leak, repair or replace components as necessary; check for proper function of the crankshaft and camshaft position sensors, and the wiring to the ECM from the sensors, repair or replace components as necessary; check the fuel mix control valve for proper operation, such that it can move freely and easily, clean or replace the valve if necessary |
