Mount The Chassis Relay; Connecting The Battery Cable; System Check - Intellitec Battery Disconnect BD0 Installation Manual

MOUNT THE CHASSIS RELAY

While holding the relay in place near the chassis battery, mark the location of the two holes for the relay mounting bolts.
Set the relay aside, and drill two mounting holes. Before bolting the relay in place, route the Control Cable near the
mounting place, locate the two wires with the fuse connectors (orange and yellow) and insert the connectors in the relay
(see the wiring diagram on the next page). Follow the color code on the relay label using the wire colors printed in red for
the chassis. Install the 5 Amp fuses in the relay.
The wires connecting to the "S" and"I" terminals on the relay (purple and grey) should also be connected at this time, again
following the color code. The relay can now be bolted into place.

CONNECTING THE BATTERY CABLE

Locate the positive battery cable for the chassis battery and if possible route it across the relay. If it is not long enough you
will need to purchase a piece of cable of the same size and type to lengthen it. Carefully cut the cable near the relay. Strip
the cable insulation back about 1/2" on each end and crimp on the battery cable terminals. Connect the terminals to the
copper studs on the relay according to the label. It is important that the cable going to the battery be connected to the side
of the relay indicated on the label as "BATTERY" and the cable going to the electrical circuits be connected to the side
labeled "LOAD".
You must use two wrenches to tighten the nuts on the stud, one to turn the outside nut and one to hold the nut
on the inside from turning. The copper stud must not turn or relay operation may be affected.
If your BATTERY DISCONNECT is for a two battery system repeat the relay mounting and battery cable instructions for the
coach (auxiliary) battery. If the relays cannot be mounted close enough together for the Control Cable to reach, an 18
gage wire may be spliced into the cable to lengthen it. This time use the wire colors printed on the label in black.
Connect the black wire from the Control Cable to a good chassis ground. Connect the blue wire from the control cable to a
fused 12 Volt source that is only hot when the ignition is on such as the power lead for the radio.
The installation is now complete. Reconnect the negative cable(s) to the battery(s).

SYSTEM CHECK

Press the CHASSIS USE/STORE switch on the control panel to the "USE" position. The chassis indicating LED should
glow to indicate the battery is connected to the system. Turn on something connected to the chassis battery such as the
headlamps to verify the connection. Press the switch to the STORE position. The headlamps as well as the LED should
go out. Turn the headlamp switch off. Repeat with an interior light and the COACH battery switch.
NOTE: If there is another 12 Volt source on the coach other than the battery (some coaches have built in charger), the
COACH LED may
