Diagnosis and Repair:
1. Loose or damaged battery cable connections.
a. Inspect the battery cable connections.
i. Inspect connections for corrosion.
ii. Inspect connections for loose connections.
2. Battery charger not connected (if equipped)
a. Make sure that the battery charger is connected to the AC power supply.
b. Make sure that the battery charger is connected correctly to the battery.
3. Battery needs recharging
a. Using a voltmeter or multimeter, determine if the voltage is below 11 V. If
so, recharge the battery.
6.9 Code 488 - Intake Manifold Temperature High
(Warning)
Logic:
Engine intake manifold temperature has exceeded 185 °F (85 °C) for more than 90
seconds.
Possible Cause:
1. High ambient temperature
2. Enclosure air intake blocked
3. Coolant level is below specification
4. Radiator blocked
5. Enclosure air discharge blocked
6. Fan belt is broken or loose
Diagnosis and Repair:
1. High ambient temperature
a. Reduce loads or recirculation of discharge air to generator in elevated
ambient.
2. Enclosure air intake blocked
a. Inspect for dirt, debris, or obstructions.
b. Remove blockage or snow/ice buildup as applicable.
3. Coolant level is below specification
a. Check coolant level.
b. Add coolant as necessary.
