TROUBLESHOOTING GUIDE
If a problem exists in only one head, a strobe tube may have burned out, or there
may be an open electrical connection in the wiring harness or strobe head. Check
connections at and between the strobe pack and the strobe head, including all
wiring. Replace the malfunctioning heads and/or wiring harnesses if necessary.
If none of your heads are flashing, follow these steps to determine the problem:
1. Check all fuses, including those at the battery, at the switch panel, in the
dash, and on the pack (if applicable). The RP242 and RP244 have
automotive “blade” type fuses. Remove these fuses, and check them to
confirm they have not blown. Replace any blown fuses with only fuses of
identical values. Replacing the fuse with the wrong rating may damage your
pack and/or vehicle, and will void your warranty.
2. Check the power and ground wires to your pack. With the vehicle turned
off and while the pack is running, measure the voltage across the red wire
(pin 1) and the black wire (pin 2) of the PWR connector on the power pack.
Push the probes of the test meter down into the connector at the wire entry
points to contact the terminals for the measurement. A nominal 12.5 volts
should be present. Low voltage to the pack can cause erratic flashing or
even complete failure of the heads. A minimum of 9.5 volts should be
present for the pack to operate properly.
If you do not have proper voltage present your power or ground is bad. Skip
to the section on Checking a Bad Power or Ground Connection.
If your pack is receiving sufficient voltage then continue to step 3.
3. Check the red wire on the CTRL connector to be sure that +12VDC is
not applied to it. The red CTRL wire is used for pattern select. Touching
AND RELEASING this wire to +12VDC changes the flash patterns. A
constant voltage applied to the red wire on the CTRL connector will prevent
the strobe pack from flashing.
4. Check that the proper voltage is reaching the necessary CTRL inputs.
The black and white wires on the CTRL plug should have +12VDC. With
the vehicle turned off and while the pack is running, measure the voltage on
the black and white wires of the CTRL connector. Push the probes of the
test meter down into the connector at the wire entry points to contact the
terminals for the measurement. A nominal 12.5 volts should be present. A
minimum of 9.5 volts should be present for the pack to operate properly.
