    So due to things i couldnt control this year, I am not using my new Superduty for plowing. I have an issue with my current plow truck. It is a Chevy, and has hideaway strobes, as well as a roof mounted LED strobe light. The LED strobe works fine. The hideaways however are acting very strange. When i flip the switch they come on for anywhere from 2- 30 seconds. Then they stop. Sometimes they come on while driving. or when i drop the blade or close a door. Or when the truck is sitting they start flashing. Any ideas?

    Sounds like a short. Check ground at brain box and all connections. Make sure they do Not have power when checking. I've learned the hard way.

    Sounds like bad ground. That does many strange things.

    this is going to sound very stupid, but where would the ground likely be?

    Do you know where the brain box is?

    I would follow the wire from the Hideaways. Most times they may only be grounded to the cab or the truck bed. That may be okay in ideal situations. When you add the cold, road salt and jarring around, it may have created a bad ground. Try to at least ground them to the frame. or run a ground from the point they are at to the frame. Make sure to scrap any paint of to help ground better.

    Whelen states to run a ground directly to the battery. They even tell you the gauge to lengthen in their PDFs.

    Okay, thanks. I am still waiting for my flashers. The Atomic cab lights are back ordered. And they are waiting to send the Feniex cannons until then. I will have no problem running everything to battery from cannons.

    30 years ago I used to rebuild rewire the old style flasher arrows the state uses during road work. I have several rolls of about 30 feet of loom with ten different color 14 gauge wire inside. I am just going to keep them all inside for spares or if I need them for anything else.

    For the two color Cannons I am guessing one hot for each color and a hot to change flash pattern and ground. Although I will pick up hot for Back ups at the light itself.
