DESCRIPTION

BE SURE TO OBSERVE PROPER
POLARITY WHEN EXTENDING
THE FLASHER WIRE.

The wire lead marked with a
gray stripe is positive (+); the
unmarked lead is negative (-).

3. Test for shorts and

interference.

A) Reconnect the power supply. If the Power LED lights and the

IR Test LED stays off, unplug the connector from the power
socket and proceed to Step 4. The following LED conditions
show a fault:

• If Power LED is off there is a short between +12V and GND.

• If IR Test LED is on or flickers blue there is a short between

DATA and GND or interference is present.

Before you proceed to Step 4 consult the Troubleshooting
Section beginning on page 14.

4. Plug the flashers into the

flasher outputs. If you need
to extend the wire, use
a 2-conductor 16 gauge
or larger (See “Tech Tip”
on page 6).

Route the connecting wire to the IR Main System Unit. Connect
the 3.5mm plug into the jack labeled “Flasher Output” on the
MSU250 (Figure 7).

“TECH TIP”

Make all final connections

to the MSU before

connecting the power

supply. This will avoid

potential damage

to components.
