Whelen CSP690 erratic operation

    A couple years ago myself and a buddy installed a Whelen CSP690 kit in my 04 GMC 2500 HD. I have all 2 hideaways in the front and 2 in each of the rear tails. Sometimes when I'm out plowing especially if its real cold I'll notice that the strobes won't work. I will leave the switch on and they may start back up. I was out earlier making sure all my plow stuff was functioning correctly, flipped the switch and they worked fine. Wondering if anyone else had had the same problem? The control unit is mounted under the rear seat so cold I wouldn't think should bother it. Thanks for the input.

    Sounds like you haven't got the backs of the connectors sealed up. Did you fill the backs of the connectors with silicone to keep the water out?

    yep,what he said.Make sure your connections out at the strobes have plenty of dielectric grease in them.Keeps the moisture out.

    Thanks guys. I went out and took the tail lights apart and covered everything in dielectric grease. We had done that when we installed them but it had disappeared. All the connections were still in good shape with no corrosion. It is quite amazing how much junk and dirt gets in those tail lights. Hopefully that takes care of the problem.

    You have to silicone the backs though, thats where the water gets in. The silicone doesn't get washed away like the di-electric grease does.
