26 Revision 4 – 1-7-2008 FTB 312-4
Removal
1. Disconnect the wires leading to
capacitors.
2. Remove the hold-down screws.
3. Lift the capacitors from their receiving
holes.
Replacement
1. Reverse the removal procedure.
2. Verify that wiring is in accordance
with the wiring diagram in Figure 2-7.
Wires must be replaced exactly as
removed. In some instances, a quick-
connect wire terminal does not seat
properly if it is not placed on the
terminal cluster exactly as it was
before removal. This occurs by
interference between the insulation on
the wire terminal and the insulation
surrounding their terminal cluster on
the capacitor. Flash Technology
recommends that you lightly squeeze
the quick-connect wire terminals with
pliers before reinstalling them over the
capacitor terminal blades.
Timing and Trigger Board Assembly
(PCB1)
PCB1 is mounted on the left side of the
component bracket.
Removal
1. Remove all green connector plugs
from PCB1 headers.
2. Loosen (but do not remove) the four
screws located near the corners of the
board.
3. Lift the board from the bracket.
Replacement
1. Cut the appropriate program jumpers
according the board just removed.
2. Reverse the removal procedure.
Input Power Module
Removal
1. Remove all accessible wires and cable
connectors attached to the module and
to T1 located under the module.
2. Loosen the truss-head screws in the
base that fasten the module to the base.
3. Remove the screw under the ground
terminal to the left of TB4. This screw
fastens the module to the component
bracket.
4. Carefully slide the module to the right
and lift it out. Ensure that connectors
are not bent while doing so.
5. Remove any additional connections
necessary to remove the module.
Replacement
1. Reverse the removal procedure.
2. Verify that wiring agrees with Figure
2-7 and restore the wire routing to its
original state.
Power Transformer (T1)
Removal
1. Remove the Input Power Module.
2. Remove the four screws holding the
transformer to the base plate and
remove the transformer.
Replacement
1. Reverse the removal procedure.
2. Verify that wiring agrees with Figure
2-7 and restore the wire routing to its
original position.
Component Bracket
The Component Bracket supports the
capacitors, terminal blocks, PCB1, PCB2,
and other components.
