load (Common or C terminal) of the compressor.
Note: Some models have a cold control switch installed in
this lead.
7. Cut the compressor AC power wire in half inside the elec-
trical box.
8. Cut the piggy back terminal off the end of the Black wire
supplied with kit. Strip insulation back 1/2" on all three
wires and connect together with the wire nut. Using elec-
trical tape, secure with wire nut.
9. Connect the remaining end of the Black wire to the #5
terminal on the new start relay.
10. Connect the first yellow wire from the kit and connect
the insulated flag terminal to terminal #2 on the new start
relay. Connect the other end to the fan run capacitor
terminal marked HERM.
11. Connect the insulated flag of the second yellow wire to
the #1 terminal on the new start relay. Connect the other
end of the second yellow wire to one terminal of the new
start capacitor.
12. Connect the third yellow wire (non-insulated terminal) to
the C (common) terminal of the fan/run capacitor. Place
the other end of the third yellow wire on the remaining
terminal on the new start capacitor.
