Fault 52: Charging System High Voltage

InfoCenter Display:
Fault Description
The 12 V alternator is producing a voltage above 16.3 V.
Charging system (alternator) is producing a voltage that the TEC has determined to be out-of-range on the
high side.
Circuit Description
The 12 V DC alternator is designed to be integrated with the engine. It provides energy to run the engine and
maintain 12 V battery charge.
Recommended Service Actions
Step 1: Verify that the fault repeats.
1. Clear the system faults from the InfoCenter. Refer to
2. Operate the machine.
Pass
The fault did not repeat. Go to
Note:
If the fault does not repeat, an isolated event has occurred.
Fail
The fault repeated. Go to Step 2.
Step 2: Check the voltage of the 12 V battery with the engine running.
1. Start the engine
2. Monitor the 12 V battery voltage using a multimeter.
Pass The battery voltage is between 11.5 V to 14.5 V. Go to Step 3.
Fail The battery voltage is not between 11.5 V and 14.5 V. Replace the alternator as shown in the Engine
chapter of the Greensmaster TriFlex 3320/3420 Service Manual, then go to
Service (page 21)
Step 3: Check the continuity of the alternator wire feeding back into
the TEC controller.
1. Disconnect connector P1 at the primary TEC controller.
2. Locate the white wire at input 12.
3. Unplug the alternator.
4. Locate the white wire in the alternator harness plug connector.
5. Using a digital volt/ohm meter, test for continuity between both ends of the white wire.
