Good grief, what's all this talk about a "generator" and "if" it works. :h
To the OP - in your original post you said your employer has a 24' travel trailer you'd like to use for a trade show and have the exterior lights on it flash to attract attention to your display. The solution is simple - if the trailer isn't already equipped with a battery (which it should be in order to tow it anywhere anyway) install a basic Group 24 deep cycle battery on the trailer tongue, connecting it properly so the positive cable is connected to the battery positive terminal and the negative cable to the negative ... now Pin 4 on the trailer's Bargman connector will have + 12.6 vdc, Pin 1 will be negative. The negative side of this 12 vdc system is already hard wired to the trailer's lights so in order to have the exterior lights come on all you have to do is connect Pin 4 on the Bargman connector (your + 12 volt source) to Pin 3 on the connector which is the positive side of the trailer's exterior lights.
If you use a short length of wire or a flat fuse to do this then the lights will simply come on and remain on but if you instead use a flasher the lights will flash on and off, just as you had asked in your original post. Just go to any automotive supply store and ask for a heavy duty flasher ... if you'd rather not install it in a box with a fuse and switch as I did then just bend the pins so you can simply plug the flasher directly into Pins 3 & 4 of the Bargman connector and as long as it's inserted the lights will flash. To stop the lights flashing just remove the flasher.
Thanks for the explanation. So in essence I need to get:
1) Deep cycle battery
2) "Jumper" to connect pin #4 to pin #3
3) EL12 Flasher (if I want them to flash)
That sounds simple enough, thank you. So based on your diagram, all I really need to figure out now is how to get power from my battery to the #4 and #1 pins, correct?
