I got this one I have plenty of hammers. I just don't know how to use them I wound up going to pneumatic nail guns. Maybe I could just pull the safety and shoot the **** out of it!!!!!!
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
I used a 24 to 12 volt power converter. The power runs to the back of the truck and through three relays (2 for turn signals and one for the running lights) individually and out to the civy plug. I then ran spliced in wires from the nato plug to relay that basically power the relay and allows the 12 volts through to the plug
Nice looking unit!Here's a link to the ones I've been building, they are very similar to the one Sierra117 made:
Civi Trailer Lights
Humm... didn't know about the surge current. Doesn't sound like the controller I found will work then, as it is only 20 amps total, which is only 8 amps more than required power.The problem with running trailer brakes off a voltage converter isn't the power required to fully engage them, about 6 or so amps per axle, but the surge current when they are first engaged which can be many times the operating current.
Yes, 24v stuff seems to be $$$! The converter that I was looking at was just under $150 bucks! And it was from australia too!You might be able to get a proportional controller to work because it should control the surge current, but I'd talk to the manufacturer to confirm the peak current requirements. There is an outfit in Australia that has a 24v brake controller, but it's pricey!

Now that I have heard it explained, seen how it is installed, and know what I am looking for, I think this is the way to go after all. It is less cost, seems easier to do, and if a relay ever goes bad, easy to fix. Thanks for the Help Guys!Yep, three relays with 24v coils, like Sierra117 (do an E-Bay search for "24v relay", look for something like this: GPS GSM GPRS car tracker car alarm accessory Relay 24V | eBay A little searching will find you ones in the USA).
Trigger the relays with the 24v left and right stop/turn plus the tail signals going to the composite lights. Connect relays to your 12v source and use their outputs to drive the trailer lights. The 12v brake light circuit will connect to your brake controller to trigger it.
Yep, get sockets for them too. Although 1/4" spade connectors will work also.
I've been reading this thread and maybe I missed it but, why must it be a 5 pin relay? As long as you get a normally open 4 pin relay it will work fine. I used 5 pin relays on mine just because that is what I had. On my 5 pin relay, I have a terminal I didn't use, pin 87 is normally closed and not used. Pin 87a is normally open.
