Roadmaster 751428 - Manual (Page 3)

continued from preceding page
(Figure A).
For all ROADMASTER braking systems except Even
Brake — using a butt connector, connect the green wire
to the motorhome monitor wire.
Wire the switch to power
8. Power for the switch can come from either the battery
or the fuse block. The fuse block is typically an easier
connection; however, it cannot be used if the vehicle has
retained accessory power (see page one).
Option 1 — Power from the fuse block
Identify a circuit in the fuse block that is constantly
powered when the ignition key is in the “tow” position
(Figure B). Use the included fuse tap to attach the red wire
to the “cold” side of the fuse socket, as shown in Figure
B.
Note: the fuse tap cannot be attached to a low-profile
mini fuse. If necessary, replace a low-profile mini fuse with
a standard mini fuse of the same amperage.
Be certain to install the included 10-amp inline fuse
as shown.
Option 2 — Power from the battery
Using the provided 10 amp fuse (Figure A), connect the
red wire to the positive terminal on the vehicle’s battery.
Note: if the vehicle’s battery must be disconnected
for towing and a battery disconnect device has been in-
stalled, make certain that the red wire is connected to
the positive side of the battery disconnect device. In this
manner, 12VDC+ will be present when the battery is dis-
connected.
Test for proper function
After the stop light switch has been installed, test for
proper function…
1. With a circuit tester, verify 12VDC+ on both stop light
spade connectors with the brake pedal depressed.
2. With a circuit tester, verify 12VDC+ on only one spade
connector with the brake pedal released.
3. With the vehicle’s engine on, verify that the brake lights
illuminate only when the brake pedal is depressed.
4. With the engine still on, depress the brake pedal to its
farthest extent, then allow it to fully return. Make certain
that the stop light switch bracket or other kit components
do not impede the full and complete movement of the
brake pedal.
When the installation is complete, verify that the
brake pedal retracts fully.
Unless they are installed correctly, the bracket and/
or other kit components may impede the movement
of the brake pedal.
If the brake pedal does not retract fully, the brakes
will be applied continuously, which may cause severe
tire and/or brake system damage, as well as other
consequential, non-warranty damage.
Failure to follow these instructions may cause prop-
erty damage, personal injury or even death.
