wiring issue

Everyone,

This isn't a Farmall issue exactly, but I'll take whatever info you can provide.

I have a 1947 Farmall H, 6V setup. I also have a hay wagon I use for Halloween rides, etc.

Last year, the local police asked that I add a flasher system to my wagon for safety reasons. My neighbor had an old flasher set (the type you use when towing a car) that hooks into a truck receiver that he wired up for his new John Deere. It is a 7 way pin connection. I used his tractor and everything worked wonderfully. This year, I plan on using my tractor. Since I have a 6V system on my Farmall, I wired up the system shown using a standalone small 12V battery. It doesn't work. I don't know if the existing wiring on the hay wagon is messed up (its been sitting out in the elements for a year), or if the issue is with my circuit. So, can anyone tell me if what I put together is correct? In the meantime, I'll troubleshoot the wagon's electrical components.

The negative post on the 12 volt battery needs a connection to the ground side of the lights

Make sure on the wagon side the #1 pin has a connection to ground (to the frame),or, all the way to the lights.There should be 2 wires at the lights,1 positive,from your flasher,1 negative-ground. Mark.

The flasher is hooked in series with the lights (which reduces the voltage to each) and the lights as shown do not have a ground. There should be a ground wire from the flasher to the negative terminal of the battery and two wires from the lights to the negative of the battery to complete their ground.
The lights and flasher must be hooked up in parallel, which needs the flasher and each light must have a wire from the positive of the battery to each one and a ground wire from each to the negative of the battery. One wire could be brought from the battery to a position and then 3 wires (like a Y) going to the flasher and the lights. The same would be done for the grounds.

?The flasher is hooked in series with the lights (which reduces the voltage to each)?

The diagram shows the flasher hooked up correctly. The Flasher is merely a pulsating on-off switch controlling power to the lights. When the flasher is on it is basically a dead short so there is no reduction in voltage to the lights.

?The lights and flasher must be hooked up in parallel, which needs the flasher and each light must have a wire from the positive of the battery to each one and a ground wire from each to the negative of the battery.?

NO! With the flasher in parallel to the lights, it would be a dead short across the battery when on and would quickly let the smoke out and make toast of the flasher.

I am sorry,the flasher I thought was a flashing light like on the cab of a tractor. This flasher I understand now is the flasher for the lights, like a turn signal. So it needs to be connected to the lights in series as shown. Just be sure the lights have a good ground. That is what makes the flasher work. If they are not grounded correctly, then there is not enough amperage to make the flasher operate.
