So I got a strobe problem

    This is what I've got, 90watt 6 head whelen supply. I use 4 heads on two switches. I was out and had the strobes on and the unit just quit. It was not hot, had only been on a couple of minutes. It just quit flashing the strobes and was humming. I have checked through all the connections and neither switch works, just makes the power supply hum. Would this indicate anything specific? Maybe I should send the unit in for warranty.

    After seeing the pics of a members install in the chevy section, I think that I am going to reinstall mine and re wire just to make sure that is not the problem.

    Any ideas??

    When I first started using mine (Whelen), they worked fine until I started plowing. Somehow the strobe heads got a bit wet and only worked intermittently. I sealed off all the connections with silicon caulk and now everything works fine.

    If you unplug all the strobe heads and turn it on does it still hum ? Plug them back in one by one and see which one makes it stop working.You may be able to figure out which cable or bulb it is,or if it's they unit.I would assume from the humming noise,thats it may be a bad unit.

    If it's a cable or bulb problem,you may have water in the connections,or a shorted cable.Follow the cable to the bulb and see if it's pinched or grounded anywhere.I hope you used water proof connectors.

    Thanks for the speedy replies. I will look over connections and try the process of elimination.

    Strobe problems

    It is very important to add dielectric grease to the connections for strobes if used in salt/snow conditions. They don't say this in the manual but the Molex connectors are NOT waterproof. I sell CODE 3 products and have seen this problem MANY times with my customers. Add a squirt of dielectric grease to each of the 3 female 'prongs' on the wiring harness and that should take care of your problem!

    A little off the subject

    When installing strobes it is preferable to mount them in the bottom of the housing and at least 3/4 of inch away from the outside lens.

    Maximum wattage per strobe should be 22.5 watts ( or less ) to prevent melting of the housing.

    10 watts per strobe is acceptable for night use only...day use at least 15 watts should work out well.

    Some 6 head power units need to have 4 on the first switch to operate properly. check your install inst.

    Agree on the H20 problem or loose wires. Have had loose conn's cause this problem on other units. Use the Deutch conn's to eliminate alot of problems.

    well i have a nova 606 and i was runing four heads off of one switch.well it lasted about 3 hours and it cooked the switch.i now run a 3 switch setup on all my trucks the switches and the nova 606 are double fused.one fuse at the battery and one at the switches and power supply.once i did get water in my beacon so it started cutting in and out.plus it was making a funny noise.i also had a bad connection to the power supply.that stumped me for days.
