TROUBLESHOOTING GUIDE
One Side Not Flashing
1. If a problem exists in only one head, you need to determine where the problem lies:
•
The strobe tube may have burned out
•
There may be an open electrical connection in the wiring harness or strobe head
•
The circuit may have failed.
2. First determine whether the failure is in the strobe tube. Unplug the two strobe head
cables and flip-flop them, plugging them into the opposite connector they were just
plugged into. If the same head still doesn’t flash, you can assume the pack is probably
functioning properly and you should skip to Step 3. If the original failed head is now
flashing, and the other head has stopped working, then you can assume the problem is
in the circuit. It will have to be replaced or repaired at the factory.
3.
If one of the heads will not flash when plugged into either of the outlets on the pack, you
will need to determine whether the problem is in the cabling or the head itself. This can
be done by disconnecting both heads from their respective cables and plugging them
into the opposite cables. If the same head fails to flash on both cables, and the other
head works on both cables, then you can assume the head is bad and will need to be
replaced. If both heads flash on one cable and fail on the other cable, then you can
assume the cable is faulty (as long as you followed step 2 to verify the problem was not
in the pack itself) and you will need to replace the cable or connectors.
Both Sides Not Flashing
1. Check all fuses, including those at the battery, at the switch panel, or in the dash (if
applicable). 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 your pack is receiving sufficient voltage then you can skip to Step 3.
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.
3. Check each head. If the leads in one of the heads have shorted out, the output
voltage of the other heads may be held down as well. To test for this, unplug all of the
heads and plug them in individually. If your problem is a result of a shorted head, then
the other heads should function properly if the faulty head is no longer connected.
Note: A burned out strobe tube does not cause a short and will not affect the
operation of the remaining heads. If the problem is not with a shorted head and if
proper voltage is reaching the pack, the problem is most likely internal to the pack.
