3. Look into the component box to determine a
convenient back side location near the existing Zettler
light relays (C, Figure 3a) to install the three 725 light
relays (D, Figure 2, Ref. 1) from the kit contents or
use the suggested layout for installing the relays as
shown in Figure 3a. Using the slots as guides on
the 725 relays, drill 1/8" holes into the back side of
the component box. Install the new relays in the box
by securing them with the #8 x 5/8 hex washer head
screws (Ref. 9). Add RTV sealant (Not Included) to
the screws if necessary. Install the relays with the
DC posts facing up and the AC posts down for more
accessible wire connections.
4. The DC and AC detail configurations of the new 725
light relays and the existing Zettler light relays are
shown in Figures 3b and 3c. Refer to these figures for
relay disconnection and connection points.

5. Note: The 725 light relays shown in these installation
instruction figures are for replacing damaged Zettler
light relay 2. Zettler light relay 1 replacement will
be similar; the differences will be mentioned in the
instructions and not shown.
6. On Zettler light relay 2 disconnect the existing 12 AWG
wire (E, Figure 4a-b) from the AC distribution block
spade. This wire should be leading from distribution
block 2. On Zettler relay 1 disconnect the wire leading
distribution block 1 from the same spade.
