Locate the new resistor with the wire designations:
Red Wire = "Resistor Top Right" (P/N 306237-Q01)
Black Wire = "Resistor Top Left" (P/N306237-Q02)
Apply a thin layer of thermal grease from the supplied blister pack
to the back side of the resistor mounting bracket to aid in heat
conduction when the resistor is dissipating heat into the drive sheet
metal.

2. Attach this resistor to the top of the half bridge assembly (red wire

on right) using two new screws supplied in the kit (Figure 4).

Figure 4. Resistor Mounting Locations.

3. Attach the wires as indicated at their terminated ends:

Red wire = J1 (+) INV using pliers
Black Wire = NEG CAP BUS using the Phillips screwdiver and
one of the screws you previously saved.
Refer to Figure 5.

Figure 5. Resistor Mounting Terminations.

4. Locate the new resistor with the wire designations:

Red Wire = "Resistor Bottom Left" (P/N 306237-Q03)
