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 RP966 and RP996 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 POWER connector on the strobe
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 13.8
volts should be present. Low voltage to the pack can cause erratic flashing
or even complete failure of the heads. A minimum of 11.0 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 Power connector to be sure that +12VDC is not applied to
the white wire. The white wire is used for pattern select. The patterns are
changed by touching AND RELEASING this wire to +12VDC. A constant
voltage applied to the white wire on the Power connector will prevent the
strobe pack from flashing.
4. Check that the proper voltage is reaching the necessary ENABLE
inputs.
The black and red wires on the ENABLE plug should have +12VDC. The
white wire should also have +12VDC if the jumper is set for 3-Pair Head
Select (see pages 4 and 9).
