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 pak 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
pak (if applicable). The RP242, RP244, RP320, RP330, and RP330Q paks all have
automotive “blade” type fuses. Remove these fuses, and check them to confirm they have
not blown. The RP906 has a fuse located inside the cover. There is an access panel in
the upper left hand corner of the cover, which can be opened by removing the two screws
holding it in place. Using long needle nose pliers, grasp the fuse and remove it for
inspection. Replace any blown fuses with only fuses of identical values. Replacing the
fuse with the wrong rating may damage your pak and/or vehicle, and will void your
warranty .
2.
Check that the proper voltage is reaching the pak. With the vehicle turned off and while
the pak is running, measure the voltage across the red wire (pin 1) and the black or blue
wire (pin 2) of the PWR connector on the power pak. Push the probes of the test meter
down into the connector at the wire entry points to contact the terminals for the
measurement. Note this reading. A nominal 12.5 volts should be present. Low voltage to
the pak can cause erratic flashing in the heads or even complete failure of the heads. A
minimum of 9.5 volts s hould be present for the pak to operate properly. If you do not have
proper voltage present skip to step 5. If your pak is receiving sufficient voltage then
continue to step 3.
3.
For Optimax paks: Check that the proper voltage is reaching the necessary CTRL inputs.
Using the correct chart from Table 1 in this manual which corresponds to your Optimax
power pak, select your desired flash pattern and note which wires are necessary to
connect to +12VDC. With the vehicle turned off and while the pak is running, measure the
voltage across the black wire (pin 3) of the PWR and any of the wires of the CTRL
connector which need to have power applied to them for your desired flash pattern. Push
the probes of the test meter down into the connector at the wire entry points to contact the
terminals for the measurement. Note this reading. A nominal 12.5 volts should be
present. A minimum of 9.5 volts should be present for the pak to operate properly. If you
do not have proper voltage present skip to step 5. If your pak is receiving sufficient
voltage then continue to step 4.
