7.03.001 Low Skid Voltage (Trouble Shooting Guide)

This Policy is Under Development. If questions please contact Area Manger.

Purpose

The purpose of this trouble-shooting guide is to assist you in diagnosing a Low Skid Voltage fault.

Procedure

This procedure applies to all units that are currently in service in the field, at a repair shop, and in storage yards.

Before any work is performed a JSA must be completed according to Flogistix procedure along with any customer requirements before any work is started.

Help guide to trouble shooting a Low Skid Voltage fault.

Step 1: Start by checking your battery voltage. Battery voltage needs to be around 12 V on both batteries. If batteries are below that charge them until they are back to normal operating voltage. While charging check the serpentine belt and alternator pulley condition. If the belt is frayed or cracked it could cause you to have a slipping belt, not allowing the alternator to charge sufficiently. Also ensure the tension of the belt is set correctly, too much slack in the belt will cause the same issue. Replace if needed.

Step 2: Next you will test the battery. Using a load tester, apply it to your battery and test the battery. If the battery fails the load test it needs to be replaced due to not having enough capacity to operate under a load. If the battery is faulty then it most likely overloaded the alternator causing it to not charge sufficiently. The alternator output should be above 13 V while running without any charging cables applied. Follow the procedure below.

1.2. 3 Gas Engine Alternator/Charging System

Step 3: If battery needs to be replaced due to a failed load test, replace battery. After replacing or charging battery back to sufficient charge start the engine and begin the alternator test by using your digital multi-meter. Set the meter to measure in DC Voltage. After setting your meter apply the positive lead to the output wire of the alternator, then apply your negative lead to the frame of the alternator. If the reading is below 13 V the alternator will need to be replaced.

Did this correct your issue? If not, continue to step four.

Step 4: Next, if you are still getting a low voltage alarm verify the output wire from the alternator is not cut or burned and not allowing voltage through it. Also verify the nut is tight holding the wire in its termination.

If issues continue after using this diagnostic sheet, contact your area lead for further instruction.
