Step 4

  • Without removing any electrical connections, open the left side of the column as wide as practical.
  • This exposes: GALILEO’s internal power supply, The battery fuse, The diagnostic LEDs on the power supply’s main circuit board, and the back up batteries.

Make sure the security clamp (shown in picture) is tight before reinstalling power supply.

Step 11

  • Perform the internal voltage test linked here: page 7-5 of Section 7.3, Checking voltages.
  • If this test is not successful, it is likely that there is a loose connection somewhere between the internal power supply and the printed circuit boards. Check the wires to make sure they are securely fastened.
  • When the above test is successful, continue with the tests in the following sections:
    1. Section7, Checking hardware, voltages, and interface
    1. Either: Section 9, Running Original Upgrade 1 test software OR Section 10, Running Upgrade 2 test software
