Answers and questions
"It is not so necessary any more that I know the answers, but now I desire
more to understand the questions." Went out and pulled the wire harness loose from my trailer wheels. Blocked it up. Took off the wheels and hubs. All looked good. Hooked up juice to it, but nothing moved. Did find out how hot shorted 12v. wires get, and how fast. Aha, thinks I. Maybe the hub needs to be on there. So, I put the hub back on, spun the wheel, hit the jumper, and it works like a charm. I guess the activation of these brakes isn't really a many parts moving at a time thing. Looks like they probably move 1/8" or so. So, it looks like I need to just chase down the bad connection/ground. Which brings us to the next question. It is said these need to be hooked up parallel, not series. There are two greens coming out of the magnet. How would I find the hot and the ground? Can I just run two lines, and jump them at the first wheel, then run the wires to dead end at the second wheel? The other wires to the bulbs are all in another housing, so it is only two wires. And do I bring it back and cut the ground near the tongue, and put on two eye connectors, and screw them to the frame? Looks like all is good, just have a break somewhere in the wiring, or it got smashed somewhere. Looked formidable at first, but chasing it down one component at a time, eliminating this, and that, and gaining another level of understanding in the process is nice. Trailer lights have never been a good thing for me. I thought brakes would be similar, but since there are only two wires, not as much as lighting. There is more to the controller, and the different things different controllers do. Now that I'm going to be doing more heavy duty towing, it is nice to get an introduction to these systems, wiring them from the start, and troubleshooting them after install. Thanks for the help.

And do I bring it back and cut the ground near the tongue, and put on two eye connectors, and screw them to the frame? As far as I remember the Aus design rules forbid using the coupling as the only ground. The ground must be a wire in the harness between the two vehicles.

Thanks for the help. Steve Be ever so nice if you kept the thread together and even modify the title if that is really necessary. Electrics 101 would be a good subject to study then you could save a lot of angst. -- John G |

The other wires to the bulbs are all in another housing, so it is only two wires. full marks. It's a coil, Steve. The hot side is the side connected to the positive battery terminal. Brake and ground each fan out to each of the brake assemblies. Hot side to the green wire, ground side to the other green wire. (as you described) Now that I'm going to be doing more heavy duty towing, it is nice to get an introduction to these systems, wiring them from the start, and troubleshooting them after install.

Looks like they probably move 1/8" or so. Correct - the magnet is attracted to the turning drum, which drags the lever forward, applying the brake. So, it looks like I need to just chase down the bad connection/ground. Which brings us to the next question. It is said these need to be hooked up parallel, not series. There are two greens coming out of the magnet. How would I find the hot and the ground? Doesn't matter - they are not polarity sensitive Can I just run two lines, and jump them at the first wheel, then run the wires to dead end at the second wheel? The other wires to the bulbs are all in another housing, so it is only two wires. And do I bring it back and cut the ground near the tongue, and put on two eye connectors, and screw them to the frame? GENERALLY one green wire from each magnet is joined together and brought forward to the trailer connector, and the other green wire from each magnet is connected to the trailer frame with an eye connector and screw. 2 brakes on each side? you can connect the two together and ground them on one screw. The ground from the trailer connector gets fastened to the frame at the hitch - often using one of the hitch (ball connector) bolts. Run all the wires in as protected a location as possible - no good if they get torn off. Looks like all is good, just have a break somewhere in the wiring, or it got smashed somewhere. Looked formidable at first, but chasing it down one component at a time, eliminating this, and that, and gaining another level of understanding in the process is nice.

Now that I'm going to be doing more heavy duty towing, it is nice to get an introduction to these systems, wiring them from the start, and troubleshooting them after install. I generally run the wires through a peice of garden hose down the tongue and frame and strap the hose solidly to the frame with conduit straps. Thanks for the help. Steve |

"Richard" wrote I didn't have any scrap hose... I buy them at yard sales, particularly the very good ones for a buck or so for just such things. And some of them, the good ones with the heavy brass fittings, are worth the cost of fixing them. Right now, I just bought two trees, and they will need guy ropes for a couple of years. Got lots of hose to make protectors for the bark. I get stuff from the trash, too. I found a 50' electrical cord in the trash curbside the other day. It was cut about a foot from one of the connectors. Really heavy copper extension cord. I'd say it was a solid $25 retail. Fixit plug, $4. My truck has this auto pilot thing, and headed straight for it. One day, got two graphite rods, one with an Ambassadeur reel on it. Guess someone had parted company, and the other was disposing of unwanted items. I pile stuff up, and twice a year, have a big gar(b)age sale, most of which is profit. Steve |

Steve Here is an idea that has worked well for me on my 1/2 dozen trailers. The part that usually gets damaged, shorted, ripped, or whatever is the relatively short piece of wire between the truck and the trailer. I mounted an electricians 4square box on the trailer and ran conduit (I've used both plastic and EMT - the EMT needs a lot fewer clamps and fasteners) back to the axles and other pieces on to the lights. Use a heavy multistrand lead from trailer connector to 4square and stranded copper wires in the conduits. Put a blank plate on the 4square with the colors marked with a Sharpie. Make all the connections with twist locks so they can be changed or checked easily. Chasing down problems is sure a lot more simple with this set up. I've not needed to change out any of the stranded, but it would be really easy. -- ___________________________________ Keep the whole world singing . . . Dan G remove the seven |

Clare does indeed use the proper stuff for his. The current trailer I did with EMT. Simply because I planned on high winter elevations. Wiring the trailer in conduit down the chassis is a good thing - But there's a much better way to handle the connector whip. I put a 6-pin Round Commercial socket connector on the tongue of the trailer, and wire up a Male-Male cable for between the tow vehicle and the trailer, just like the Nose-Box on Commercial trailers. This allows for different wiring between the two - My cars are all wired with the 6-Pin Round but I have cables that go 4-Flat or 7-Round Commercial to 6-Round Commercial also. Keep an extra chunk of the proper 14-5/12-1 PVC Jacket Trailer Lead Cable on hand with one 6-Pin Round end already attached, and you can always make what you need given a few minutes time. Or just Hotwire it to the car harness with Bullet Connectors and quick-taps... Ugly, but effective. All trailers get wired Commercial style too - 2 sets of red taillights. Two for Stop/tail, and two for Turn/Tail. If you hook up to an American car it just uses the two Turn lights for Stop/Turn, and if you hook up to a Japanese/European car with a separate Stop circuit you do not need a light converter, it just plugs in. -- Bruce -- |
