Precor Error 46, Low Battery Voltage (AMT12 Only)

Probable Cause

1. Blown fuse in the positive battery wire of the AMT12 2. Faulty or poor connection on the battery or LPCA 3. Low or no output voltage from battery

Corrective Action

  1. Remove the power from the unit and move the lift fuse from the in line fuse holder on the positive battery cable
    • Measure the fuse with an ohm meter (multi meter), the fuse should read approximately 1 ohm or less
      • If the reading is significantly high, replace the fuse
      • If the fuse is open, refer to next solution before you continue
  2. Check connector of the battery cable for shorts or poor connections
  3. Enter the diagnostic program per procedure, P80 Settings or Accessing the P30 Diagnostic Software
    • Using the diagnostic program allows you to test the incline system without continuously pedaling the unit if you have an external power supply
      • Otherwise, you will need to continue to pedal the unit
    • Connect a DC voltmeter to the J3 connector on the lower PCA as follows:voltmeter common lead to terminal 3 (black wire) and voltmeter "hot" lead to terminal 2 (red wire)
    • Using the STRIDE HEIGHT Up and Down keys, operate the incline
      • The voltmeter should read about +12VDC when the incline is instructed to move upward and about -12VDC when incline is instructed to move downward
    • If either voltage measurement is significantly low, replace the battery
