Roadmaster AddaBRAKE 8800 - Connect The Motorhome Monitor Patch Cord; Test The Braking System

DAY-TO-DAY OPERATION
Connect the wiring harness;
test the break away system
continued from preceding page
3. Periodically,testthebreakawaysystem—pullthe
breakawaypinoutofthebreakawayswitch.TheAdd-
aBRAKEpedalclampwillextendwhenthepinispulled.
Insert the pin back into the switch. The AddaBRAKE
pedalclampwillretract.
When connecting the break away system, always
check the following:
• Connectthecableattherearofthemotorhome,
close to the center. Connecting the cable toward
either side of the motorhome may cause the break
away pin to be pulled when the motorhome turns,
activating the break away system.
• Becertaintherearenoobstructionswhichwould
prevent the cable from pulling freely away from the
break away switch. Do not wrap the cable around
anything — doing so could keep the cable from pull-
ing the break away pin, preventing the system from
activating in a break away.
• Makesurethecableisthecorrectlength…
 • The cable must be long enough to prevent
the break away pin from being pulled out
during normal towing — make certain there
is enough slack to allow for sharp turns. If
the cable is not long enough, the break away
system will activate even though the towed
vehicle has not detached.
 • Thebreakawaycablemustbelongerthanthe
safety cables. This will prevent the break away
system from activating if a component of the
towing system has separated, but the towed
vehicle is still held by the safety cables.
 • Make certain that the cable is not too long —
it should not hang down to the extent that it
may catch on obstructions, or drag on the
ground. This much slack could allow the cable
to be pulled inadvertently, activating the break
away system.
 • Ifyouhaveatelescopingtowbar,allowenough
slack for the tow bar arms to be fully extend-
ed.
• Leave the break away pin in place, even when
the vehicle is not being towed. If the pin is not in
place when AddaBRAKE is connected, the break
away system will be activated — the air cylinder will
extend and will not retract.
Failure to follow these instructions may cause
property damage, personal injury or even death.
Step G
Connect the motorhome
monitor patch cord
Note: if both ends of the monitor wiring harness were
connected to open terminals on the electrical sockets,
the motorhome monitor patch cord is unnecessary. Re-
fer to Steps C and F under “Initial Installation.”
1. Atthetowedvehicle,connectamalebulletconnec-
toronthepatchcordtothefemalebulletconnectoron
themotorhomemonitorwiringharness.
  Attheback ofthemotorhome,connecttheother
malebulletconnectoronthepatchcordtothefemale
connectoronthemotorhomemonitorwiringharness.
  Allowenoughslacktopreventthepatchcordfrom
being pulled loose when the motorhome turns. If the
cordis toolong,wrapitaround thetowed vehicle-to-
motorhomeelectricalcord.
Step H
Test the braking system
Note: the motorhome and towed vehicle must be
stationary for the system test, and ready for towing —
all components of the braking system must be properly
connected and receiving power. Then, according to the
manufacturer, make all adjustments necessary to pre-
pare the vehicle for towing. These adjustments may
include: turning the ignition key to the “tow” position;
pulling fuses; disconnecting the battery; and setting
the transmission to a particular gear or in a particular
sequence.
Refer to the owner’s manual, or call the dealership
or the manufacturer for vehicle-specific information.
1.Confirmtheproperoperationofthesupplemental
braking system: depress and hold the motorhome’s
brakepedaldown.TheAddaBRAKEaircylindershaft
and pedal clamp will extend (after approximately two
seconds).Then,releasethebrakepedal.Atthetowed
vehicle, the AddaBRAKE air cylinder shaft and pedal
clampwillretract.
2. Confirmthatthemotorhomemonitorisfunctioning:
theLEDwillilluminateafterthemotorhome’sbrakeped-
alisdepressed(afterapproximatelytwoseconds),and
stopilluminatingwhenthebrakepedalisreleased.
If the LED does not illuminate…
…at any time when the motorhome brake pedal
is depressed, it may indicate that AddaBRAKE is
not functioning. If AddaBRAKE is not functioning,
