    several different things. Grounds for your strobe heads, You didn't seal your connections and they've got junk in them or... Your plugs going into your pwr supply aren't tight!

    How do I ground the heads? I thought the black center wire was the ground? and yeah I think it might be the plugs because I used a 5ft extentions on the back by the taillights on all 4 wires so thats prob it. should I take em off and put dilectrical grease in them?

    Die Electric Grease on the contacts, but put some silcone sealer or something that won't let water/junk into the connection.

    Grounding should take place when you wire up to your pwr supply but with you stating that you put a 4' extention on... Your problem might be with the wires in the extention. Put an OHM meter on each wire to see if you get the pwr completely. Some after market wires have really super cheap wires and plugs.

    Oh you didn't mention that... You need to check the pwr out from the pwr unit. You may have a bad one. Couple of things you can do...Unhook all but one of the strobe wires at the pwr unit. Turn it on. Do same with all the outlets. If nothing you may have a bad supply or just the ground or even the fuse that's on the top of the strobe pack.

    I'm about 70% sure that you may have a bad supply at this point. Where do you have the supply mounted? If it's exposed to weather or has no air flow that could be your problem.

    Good luck with it.

    Just a thought but when 1 of my heads wire goes bad the whole system is out. Try unpluggin all 4 heads at the power supply. Then try plugging them in 1 at a time. You may be able to find which wire/head is bad if as stated above the power pack is not bad.

    I doubt its bad it workerd perfect last night, it mounted high and dry under my drivers seat very low hours on it. I bet what you said about the cables connections being bad is right. whats the point of the wire thats just sticks out of the cable thats uncoated.

    If it's like a metal wire its to make it easier to open up more of the outer jacket so you can spread the red, white, black wires further apart. Not sure why you would want to.

    Have you tried what I suggested about pulling all 4 stobe head cables out? Once you do this you can figure out which cable has the bad connection.

    this may sound like a pain but take out your strobe heads and plug the strobe heads directly in the the power pack and do all the heads in all the outlets

    I had the same issue, you can hear the power supply try but no flash. the plugs going to the heads are NOT WATERROOF. I found this out the hard way. All external connections must be thoroughly be wrapped in electrical tape or something of the like. Whelen does offer waterproof plugs but this works just fine. I wrapped mine 3 years ago and have had no problems since. good luck!

    not sure if you fixed yours yet or not
    but i found mine had got some water inside the connections and shorted it out causing the system to fail
    the connectors were all brown like it had been sparking lucky i didnt have a fire

    I took one of the plugs out and just butt connected the wires and shrink wraped them and I used silicon on the plugs at the bulbs
