+5VDC Testhead Power Supply
The Testhead cooling fan assembly contains the main +5VDC Power Supply
for the Testhead. If it is determined that the supply is faulty, the recommended
procedure would be replacement of the entire assembly as described below:
1) Remove the four screws on the sides of the Testhead cooling fan assembly,
and draw the assembly towards you 2 to 3 inches.
2) Remove the five fasteners for the filter housing plate as shown above, and
remove the plate from the cooling fan assembly.
3) Loosen the two Testhead retaining screws located along the back of the
black Testhead cover, by turning them 1/4 turn counterclockwise. Using the
handle, lift the Testhead into the position shown on the next page.
4) Remove the hazard cover from the Testhead by removing the mounting
screw from each end of the cover.
5) Disconnect the supply wiring harness from connector J13 on the Testhead
Power Supply Controller board.
